Need instructions for T.R.A.C. dial hot water heater timer - not sure whether pins pushed in = off and out = on or vica versa

Posted by on

1 Answer

I thought I knew every water heater timer possible.

Never heard of T.R.A.C.
Is that a European timer?

Here's what to do. Set the pins one direction or the other. Start with cool water in tank, so it will turn on for sure when power is applied. Turn on power. Put your ear against water heater. Listen for bubbly-fizzing sound that tells you water heater is on.

Check label on side of tank to see voltage & wattage of tank. Watt rating for dual element tanks is same as element wattage, since only one element is ON at a time. Generally, 240V electric tanks are 3500, 4500, and 5500 watts. That is 16 amps, 21 amps and 23 amps. Make sure your timer has amp rating to match water heater.

    I'm the same, I dont know if when the pins are In = On and Out = Off or vice versa. As my boiler only heats the hot water and not my room heaters it's difficult to tell. So at present I either have the boiler on for a sensible amount of time, a couple of hours a day twice a day OR I have got it on for 20 hours a day!! Does anyone know? The solution answer above didn't answer it. Thanks

I have a wh21 Intermatic water heater timer. I installed the shut off and on switches. They are not working. I opened a manual and it stated to make sure the dial is pushed all the way in. I spun the dial...


You might have your Line and Load wires reversed.
Line wires come from circuit breaker.
Load wires go to water heater.
http://waterheatertimer.org/B220C.html

WH21 wiring: There are 2 Hot Line wires coming from breaker box that connect to terminals 1 and 2.
WH21 is SPST and turns off one Hot wire going to Load. So Load wires connect to terminals 2 and 3. Terminal 2 has 2 wires: 1 Line wire and 1 Load wire.
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/wh21%20-%20english.ashx

Keep in mind that WH21 is 25 amp, 2Hp 240Volt timer that will work on water heaters up to 4500 watts. Look at label on side of tank to see wattage. All appliances and motors have labels.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

Larger wattage water heaters require 30 amp water heater timers as shown following page:

I want to reset the timer for hours of on-off for out water heater but can't figure out how to push the little white teeth in or out. Model is 265-1.


1) Open following link to read about re-circulation systems:
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) Image below show typical FM1 analog timer dial with pins:
Move pins with fingernail or small tool.
To test if pins need to be moved in or out, set pins each direction and manually rotate dial clockwise and listen when pump turns on-off.
How timer operates: clock motor rotates dial continually, pins on dial move lever that turns circuit on-off.
To set current time, manually rotate dial clockwise until current time lines up with arrowhead located on inner dial.
Some timers have a selector switch: move switch to Auto, or Timer, or Timer ON. Again you can manually rotate dial and check which setting is correct.

I have this timer hooked up onto my water heater in the garage . I have instant hot water at all times . My gas bill is 5 times higher than my neighbors . Is this what is causing it ? If I unplug it where...


I think you have a grundfos recirculation pump.
This is not a water heater timer.
For illustration of grundfos system, open link below.
http://waterheatertimer.org/Water-heater-recirculation-system.html
Recirculation system is electric, but it also causes gas water heater to run more.
Unplug grundfos for a couple months to see if gas bill goes down. Your system will revert to regular water heater.

Many things can cause high gas bill. Make inventory of gas-consuming appliances: dryer, oven, stove, heater, water heater. Then inventory how often these appliances are used. Each appliance has a label with BTU listed. Add up BTUs of all appliances and compare with BTUs shown on gas bill. Call gas company about how to cut back.
Gas water heaters can become inefficient. So can any gas appliance. Look at flame inside water heater when it turns on. If flame is yellow instead of clear blue, that indicates the water heater is inefficient, and burner needs to be cleaned, or heater needs replacement or maintenance.
Call plumber for assessment and then post a question on the Tank to double check anything plumber says:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

More information about circulation system:
Notice that illustrations show a pump located under the sink.
It sounds like you have same pump located at water heater.
Both types are same thing.
The purpose is to circulate hot water to your faucet so you don't have to wait for hot water when turning faucet ON. Instead, you have to wait for cold water.

The timer located on grundfos dial determines when pump turns ON.
Link above has illustration showing how to set timer pins using your thumb or ink pin or nail file (women know nail files, so I'm relating here).
To set timer, rotate dial until current time lines up with mark. The dial rotates as time passes and has to be reset after power outage.
If dial does not rotate, then timer is broken, but it sounds like pump is still working, and running full time which is wasteful.
Next, move the pins to set on-off times. Move pins inward, the pump is ON. Pins outward, pump is off.

The hot water recirc pump in my new house was equippped w/ this timer. There was no user manual, but it was set by the installer to run the pump during awake hours and shut it off during sleep hours. ...


1) Open link below so we are talking about same type of household system
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) 15 minute interval is misleading.
Pins located on timer dial divide 24-hour day into 15 minute intervals.
You set timer pins and decide which 15 minute intervals you want ON-or-OFF. Do this by moving pins inward or outward with your thumb or ink pen. To check settings, manually rotate timer dial clockwise and listen for pump turning on-off..
Set timer pins for 4 consecutive 15 minute intervals, then timer runs for 1 hour.
After pins are set, then manually rotate dial to set current time.
Dial rotates as time passes, and pins click a lever that turns pump on-off.

3) 5-year Life span. Like all things plumbing, if you have hard water or sand-n-dirt in water lines, then pipes clog. And pumps clog.
Once motor begins to slow down, it overheats and burns out.
Water softener can keep sediment out of lines, but shortens life of water heater.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

4) Real question: do you need a circulation pump? Do you need hot water at your faucet? Can you schedule hot water use, or does recirculation pump have to run several hours per day?
Recirculation pumps causes water heater to run more, the pump consumes 25+ watts depending on pump, and water savings claims of 15,000 gallons per year are fabrication.
Realistic water savings is 700-2000 gallons per year, assuming several folks in the home use water sporadically across a full day, and each time water is used people are waiting for hot water. It also assumes that you never want cold water at the tap and that refrigeration ice maker line prefers hot water to cold.

Timer will not turn water heater ON at set time, has to be done manually. However, it will turn water heater OFF at set time.


If this is new installation, check wiring. Hot and Load wires might be reversed.
Check that ON OFF trippers are both attached to yellow dial.
http://waterheatertimer.org/How-to-wire-WH40.html

If timer worked fine before, and started missing recently, then tripper pins probably worn out.
Trippers contact mechanical lever, and push lever on-and-off.
Trippers are softer metal and designed to wear out before lever.
If lever is worn out, timer needs to be replaced, but try new trippers first.
Buy trippers at Grainger
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

How WH40 timer works:
Clock motor rotates dial.
ON-OFF trippers on dial contact lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever other direction.
Lever moves electrical contacts together, or pulls contacts apart.
When lever moves on-and-off, manual override lever also snaps back and forth with audible clicking sound.

Using q-tip, add touch of white grease to lever where trippers contact.

Grundfos is a sealed unit and not a repairable item.
The timer dial should turn.
And pins located around dial control ON-OFF functions as timer dial rotates.
geno_3245_93.jpg

Does the receptacle have power?
If receptacle has power, and Grundfos is not working, then it is broken.
Grundfos manuals for UP series pumps do not show breakdown or parts list of any kind.
http://www.us.grundfos.com/web/download.nsf/Pages

Bigger question:
Why don't you have hot water?
Is water heater functioning?
Water heater is a separate appliance from Grundfos pump.
Grundfos pump circulates hot water from tank into the lines so there is no waiting for hot water ... but hot water heater should still make hot water.
http://waterheatertimer.org/Water-heater-recirculation-system.html

Add a comment about water heater if that is also a problem.
You could have 2 problems, and water heater is main issue.

The timer is used on an Electric Point of Use 2.5 water heater. Currently I get hot water only about two hours in the evening. Before it was --on demand. I opened the timer box and one of the timer box"...


No overcharges here Ms bernarda

If I understand correctly you have Intermatic timer with a yellow dial
You have the Intermatic timer hooked to a small 2-1/2 gallon point-of-use water heater
Your point-of-use water heater is working fine
The timer turns on the water heater once a day instead of twice a day

And it seems like one of the tripper pins has fallen off the yellow dial
The tripper pin is missing and you can't find it or put it back.
You can turn off the electricity and poke around the bottom of the timer box and see if tripper pin can be pulled out using tweezers
Do you know Grainger sells Intermatic tripper pins for $1.67 plus shipping?

Do you have the auto-circ recirculation pump with timer?
If so, here is manual for that specific product:
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}

http://waterheatertimer.org/Auto-circ-manual.pdf
Manual gives instructions for a different timer dial than timer than shows on unit, so they must come with different dials.

Instructions say pegs pulled out = timer on
Conversely, pegs pushed in = timer off
You might be able to hear the pump operating to see if these instructions are correct for your recirculation timer. The kids would love a listening assignment under the sink.

To see images showing how recirculation system operates:
http://waterheatertimer.org/Water-heater-recirculation-system.html

Setting times:
Try 1/2 hour ON in morning and 1/2 hour ON in evening. Warm water will stay in pipe for a while.

Recirculation system with timer costs $10-17 per year to operate, assuming timer runs 1 hour per day with electric prices at 10 cents per kilowatt hour. Operation cost is straight line ... so if timer runs 2 hours per day, cost is $20-34 per year at 10 cents per Kwh.

Water saved might equal 5 gallons per day, or 1825 gallons per year depending on usage. Average water wasted waiting for hot water is 1/2- 2/3 gallon depending on length of pipe. Set a bucket under spigot to test your home when circulation system is not ON.

Cost of water depends on local billing rate. The municipality saves purifying water, pumping water to your home, and finally pumping and processing sewage drainwater.

If you are on a water well, the pump electricity from saving 2000 gallons a year is a dollar or two per year since water well generally consumes less than 1Kwh per day for ordinary house.

Is WH40 wired correctly?

Is timer working?
If wheel rotates and keeps good time. Then clock motor is good.
Flip manual override on and off >> if manual override is not loose and falling apart then your timer is probably good

ON-OFF Pins:
There are pins attached to yellow dial. Clock motor rotates dial until pins contact mechanical lever. Pins push the lever on-and-off.

http://waterheatertimer.org/images/WH-Off-pin-pushes-lever-400.jpg

Two types of pins, ON and OFF:
You need a brass-colored OFF pin to turn off the circuit. You need a silver-colored ON pin to turn on the circuit.

Order more pins:
Your pins may be worn out, or you don't have any OFF pins.

We have a timer on our tankless hot water heater-how do I set it to reflect the current time? It is a large dial with tiny pins to pull/push backward. I understand the on off function of the pins but need...


very simple you push the middle and turn to set it to the timing you want current timing. the best times to set a recirculating pump in a water heater is 20 to 30 min before you take a shower in the mornings 15 min is adeal and dont leave the timer on for more than 15 min which represents each pin. Remember you are trying to recirculate the cold water out off the lines and replace it with new water so next time you open your faucet you get instant hot water. ones hot water is in the line you do not need the pump. i also recomend to set the pump 15 min before you get home or before you take a shower int he afternoons there is really no pint to leave the pump all day or for longer than that because the objective is to replace cold with hot water you can even set it to turn on and off every hour for 15 min at a time if someone is home all day but remember usually the recirculating pump is there for the faucets that are far away from the water heater so if you do not used them all day and only in the morning and at night before going to bed then there is really no point to leave the pump on and waste more electricity.
