A typical time schedule might be on at 5am (for showers starting a 6am), off a 7am (when everyone is off to work or school), on again a hour or so before the first people arrive home, and off before bedtime. There will be a reservoir of warm to hot water available all the time, even after the unit is off for hours, provided your tank is properly insulated.

Can you set different programs for the heating and the hot water?


Yes, most heat-water heater timers can be set for different schedule.
Add a comment and include the timer brand and number and I will look up manual if available.

I can't be sure without going outside (it's raining) and checking my own controller, but I'm thinkin' that the arrow pointing to "even" indicates that the program will only water on even numbered days. Can you change it so it points to event and "All"?

Is the sunvic sp2 a 2channel timer please


Yes. It appears the Sunvix SP2 is 2-channel timer.
http://www.sunvic.co.uk/documentation/Programmer_Select_207.pdf

Two-channel means CH central heat and WH water heater can be programmed separately, and each can have its own timing program.
pg 3

The timer offers pre-programmed options for both CH and WH, which can be used, or program your own schedule. chart pg 5 and steps pg 3

Limitations: both channels operate on same clock time, and dip switch setting. pg 6. So the WH cannot be programmed for 5-2 weekdays-weekends and CH programmed for 24 hour.
As a convenience for varied work schedules, Sometimes people use the 5-2 weekday-weekend option so 2 days of week can have different programming, and then fudge current day setting during the set-current-time step pg2 so the 'weekend days' are actually moved to wedsday-thursday instead of sat-sun.

Option: both CH and WH timer programs can be linked and follow same programming by using copy button. pg 5

Using advance button on either side of timer, pg 3-4, WH and CH timing schedules can be overridden temporarily until next set point is reached. Then regular programming automatically resumes.
If override or Advance button is pushed for either CH or WH, it reverses whatever programming is in effect. On becomes off, or off becomes on. However if CH thermostat is satisfied and room temperature has not fallen below thermostat set point, then override will not turn CH on, but override will turn CH off. Same for WH override: If cylinder thermostat is satisfied with internal water temperature, the water heater will not turn on and heat more water, but the override can turn water cylinder off.

Unit requires Cr2033 lithium button battery. Pg 6. Probably lasts 3-5 years. Programming is protected for 30 days from power outage.
If programming is lost, change battery, the reset timer and reprogram to restore functionality.

Solution to Excessive Cold Water Wait Time With Grundfos Pump


You can install direct return line that cycles hot water directly back through drain valve on water heater, so hot water circulates independently from the cold water line. This system means cold water is available immediately, and also hot water is available immediately, but means installing additional plumbing line, and removing water heater drain valve. Removing plastic drain valve will probably break off and require hammer, big screwdriver, torch, and 7/8" drill to remove broken pieces.
Here is image:

Or use the timer feature instead of thermostat to precisely schedule when hot water will be available, and thereby also schedule when cold water is available.

I have a timer that won't hold the program time set schedule? I have paid an electrician to come out and check to make sure i don't have any shorted out wires?? Electrician didn't find any...


Question posted under 120volt Intermatic Eh10 timer.
I do not have repairs for defective timer.
EH10 has 1 year limited warranty.

Located just below the digital display is compartment for AA battery.
Display is controlled by battery.
Replace battery, press and hold reset button for several seconds to reset timer, and try to program again.
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#EH10
http://waterheatertimer.org/pdf/eh10-manual.pdf

EH10 and EH40 timers are susceptible to line noise.
If timer is connected to water heater, there is no line noise. And electrician tested for shorting wires.
But when timer is connected to fan, pump, or other type of load, then interference can be a problem.
Intermatic can provide a filter.
http://www.intermatic.com/customer%20service.aspx

Digital timers, digital water heaters, digital washer and dryer, digital water softener, digital treadmill, etc are increasingly common, yet are not protected from surge.
People protect computers and TVs, but forget other costly items.
EH10 can be affected by surge.
Install whole house surge protection:

New intermatic timer installed. I can turn on manually and it will turn off at designated time but will not prgress to turn on automatically.


If display shows, and timer turns lights on-off with manual override, then timer is wired correctly, and battery is good.
If timer will not turn ON at scheduled time, but turns OFF correctly, then best suspect is the programming.
Open following link for ST01C programming steps.
http://waterheatertimer.org/ST01C-program.html

Program1 is ON
Program2 is OFF
Program3 is ON
Program4 is OFF, etc

Review your schedule: Press Mode button until PGM starts flashing, and then press ON-OFF button until 01 starts flashing.
If Program1 cannot be set for some reason, then set your ON schedule on Program3 and ignore Program1. The timer does not mind if you have OFF set on Program2 and ON set on Program3 or Program5 or Program7 etc.

If you have multiple programs, for example different ON-OFF times for each day, then check for scheduling conflicts that will cause timer not to function as expected.

If timer is defective, contact seller about 1-year warranty.

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.

Clock turns untill pump turns on then stops. does c8866 timer work with well control box?


If I understand correctly, you are controlling 240V water well pump with Intermatic C8866 Repeat timer.

So you must be using pump to irrigate, and want to turn pump on at certain times of day for short periods ... and want this schedule to repeat continually non-stop.

1) The c8866 repeats the same program every 4 hours so this is good choice for irrigation and it just turns the circuit on-and-off so it works fine with well control box (unless you want more complex programming).
Many types and prices of cycle timers
More cycle timers

Let me give a buckshot answer and see if I hit one of the targets you have.

2) C8866 according to manual:
a) You have on-off trippers
b) First ON tripper turns on load for 32-40 seconds
c) Each additional ON tripper will lengthen ON time by 30 seconds

3) To lengthen ON time: add successive ON trippers into dial. Each successive tripper adds 30 seconds. Let's say you want ON time to be 3 minutes, you need 6 successive ON trippers.
Maximum timer setting is 240 minutes, so your ON-OFF program repeats every 4 hours.
10 Tripper pins come with timer.
Buy more pins at Grainger for 2.69

4) Did you say the clock stops running after hitting the tripper? If so, maybe you need a bit of grease on the pins ... or a new clock motor? Buy clock motors at Aplus
5) Review the wiring
Hots from Breaker connect to COM and CLOCK poles
1 Hot to Load connects to NO normally open pole
Other Hot to load connects to CLOCK pole

6) You can reverse ON-OFF programming by the following:
Change Hot to Load from NO to NC pole and this will reverse on-off programming

Can i use the timer for a water headter to trun on and off


Paragon 8145-20 is a 240V defrost timer
It is probably not best choice for water heater timer
Timer initiates defrost cycles each 4 hours.

A water heater timer should have more scheduling options.
-For example estimates show average run-time for water heater is 3 hours per day, depending on incoming water temperature, thermostat setting, and number of gallons used.
-To save money using water heater timer, you have to schedule times carefully so water heater runs less than 3 hours per day.
-Now your average electric water heater heats about 20 gallons per hour.
-Average shower uses 4-9 gallons hot water, so water heater needs to run 15-30 minutes (15 summer, 30 winter)
-Average bath uses 12-15 gallons hot water so water heater runs 45-60 minutes
-But lets say you run water heater for 1 hour and make 20 gallons of hot water. Then you take a shower, expecting hot water to remain in tank.
-Here's the problem ... cold water entered the tank to replace the shower water ... and the new cold water is cooling the rest of the tank.
-So a timer means scheduling hot water to match shower and bath events. For example taking shower and bath in immediate succession.
-Or set the timer for each individual hot water event ... for example set timer for 1/2 hour for shower, and later timer turns on 1 hour for bath, or 1-1/2 hr for 2 baths, etc
-> The flexible programming described above is not a characteristic of defrost timers.
I suggest Intermatic WH-31 240V or Intermatic T-104 240V or GE 15207. These are mechanical repeat-24 hour timers with manual override where each day has same schedule.
Digital programmable timers like Intermatic EH40 offer 7-day, 40 event programming. Weekends and weekdays can be different.
To see several box-type timers:
