Question about Hayward H Series Induced Draft Abg 100,000 Heater

Heater shuts off 10 degrees before pool reaches the set temp.

I set it for 80 and it shuts off when pool thermometer is at 70. FAQ suggests calibration but doesn't say how to do that. Ideas?

The thermistor is probably failing and needs to be replaced. You can probably replace it yourself. We sell the part at www.arrwomotor.net

I set my magic chef oven at 400 degrees,and it shuts off before it reaches the temp.


Have you checked the internal temp with an oven thermometer?

The thermostat might need calibrating or replacing, or, (if electric) the oven might be seeing an "overload" condition and shutting off.

Have pentair easy touch controls just installed new water temp sensor. spa is 88 degrees but master temp heater shuts off because it reads 104. what should i check? the thermistor/


If the Easy Touch is reading the correct temperature, but the heater is not - you need to double check the temperature of the pool water with a standard pool thermometer.
Other things to consider:
1) The water is traveling too slowly through the heater. If the water is heating too quickly, then it will shut it off. If it takes a while for this to occur, then this would not be the issue.
2) Thermostat/thermistor is incorrectly reading the temperature of the water prematurely shutting the system down.
Make sure you really are checking the temperature of the water and matching this temperature up with one of the two readings that you are getting. Don't just take the word of the displays on either unit.

Need to know how to calibrate my honeywell RTH221


This thermostat is not field servicable,you cannot calibrate this thermostat.May want to consider moving it closer to return air of equipment, for more accurate sensing of building temperature. Why do you feel that it needs calibrated? Suggest setting another thermometer on top to verify its accuacy.

Honeywell Thermostat RTH7400D


The thermostat will not cut off the A/C until the thermometer reading gets to 76.

If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.

There are ways to calibrate it, but much to involved to go into here.

One solution is to just set the thermostat at 80, knowing that it's really set on 76.

Another solution is to replace the thermostat.

Honeywell T87F Thermostat


this calibration is called the heat anticipator, this is set by the amp draw pulled through the t-stat,if you look very close at the scale you will see the word longer with an arrow ,if you push the lever in the direction of the arrow the heat will run longer .This is a very old style t-stat and is most likely out of calibration on the temp reading for the room, think of this portion of the t-stat as a stand alone thermometer,it may read 70 when the room is 74

Oven doesn't heat


I'm not sure what properly means.  If the unit is working, you can get a cheap oven thermometer to check the function of the thermostat.  Let the unit come to 350 and check the thermometer.  If it is off by more than about 20 degrees, there is a calibration change method in most oven handbooks.
If the unit is not working at all, this is another issue and needs a different set of diagnostics.
