It's most likely a temperature sensor, what is the readout on the top side control?

What's the value of y


67 degrees. There are a number of methods to solve this.

One method.

Opposite angle of 67 degrees will be 67 degrees.
Angle above this will be 180 - 67 degrees, or 113 degrees.
Angle above this, y, will be 180 - 113 degrees, because angles of a straight line must add to 180. Result is 67 degrees.

Good luck,

Paul

How long does it take to heat a spa pool?


All depends on the amount of water in the spa or pool, and the size of the heater in BTU's. The time for "Heat Rise" will vary and the answer you are looking for can't be provided with amount of info you provided. But if a general rule of thumb - the closest answer: Spa with a gas heater, 1 degree about every 90 - 120 seconds. Electric heater (vary's by KW) on average: cold to hot = 8-13 hours. Swimming pool with gas heater (no suggestion for electric) about 1 degree temp rise every 90 minutes.

Spa keeps overheating


Hi,
Faulty temperature sensor should do this to.
A floating thermometer should read water temperature within 3-4 degrees of spa controller. If it is greater than that your sensor is bad.
The hi limit is an over heat sensor it does not control the temperature of the water. If the water is heating above 118 degrees and the spa is not shutting down its Hi Limit.

I have a Pentair Mastertemp 400. It worked fine for 3 years until the temp sensor went out and both (internal and external) were replaced about a year ago. It then worked fine for about another 7-8...


You might have a much bigger issue than the temp sensor. When the heater is running hold the "pool" or the "spa" button for 12 seconds. This will show the exhaust temp, if the temp is rising above 375 degrees with in 1-2 mins then your not getting the heat out of the heat exchanger.
One other thing to check would be an external by-pass. If you have an external by-pass make sure the by-pass is set correctly. Opened or closed to much can cause the problem your having.

I just installed a honeywell 5-2 progammable thermostate.. Everything is hooked up fine and I have my days, hours wake, sleep, leave...etc all set, but when it goes on.. for example, I have it set for...


You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

I just installed my new X400 Dreamaker Spa. I filled it with water (although cold) and it has been warming up for approx. 18 hours and is only at 80 degrees? Is this normal? How long should it take to...


This is normal with the dream maker spa. The dream maker spas are poorly insulated, and only run 120 volts with a very small heater.
When the unit is first filled, the hot tub will not heat full time either. Most new hot tubs will have freeze protection below 50 degrees F. They will recirculate automatically using the friction and the pumps heat to warm the water above 50 degrees, and then the heating unit will kick on. These hot tubs do not heat while the jets are on high either, so once you are in it using the jets on high, the temperature will start to fall.

Now that you are up to 80 degrees, it should heat up fairly quick however.

I have the thermostat set for 70 degrees on the white rodgers programmable thermostat. The heat runs until the room is 70 degrees, but then the heat stops and the room cools off and the heater doesn't kick...


Based on your explanation this is an erratic operation of the thermostat, first thing that you need to check is the wiring make sure that all the wires are proper looped on the under terminals then reset the thermostat if the problem still persist I think you need to replace the thermostat. If you need further support call the homeowner techline 18002842925.

HI I have my hot tub at 104 but it will only heat up to about 80 degrees. what is my problem


If its set at 104, but only heats to around 80 degrees, then your heater is not working. Either the heating element is bad, or the pressure switch is not closing. The reason why the water heats up to 80 degrees, is from the friction caused by the mechanical shaft seal when the pump is running. Either way, you should really have it checked by a qualified spa technician. It is not something that the average spa owner can normally repair themselves. Sorry.

Spa / hot tub does not heat


Your temperature control is way out of calibration or, it's wired wrong. Remove it and check it in a glass of water. Use an ohm meter across the heater wires. As you add hot wwater, the heater contacts should open.
