Heater Turns Off 4 Degrees Low
« on: August 27, 2013, 09:21:21 am »
1999 HS Sovereign. Converted to 230V years ago. Just replaced circ pump, both thermistors, and heater.
Everything works except for being able to correctly set the desired temperature.
Set temp is 102, heater turns off at 98. With old thermistors and old heater, set temp was always maintained within
+/- 1 degree. Workaround is to use the "upper temp" adjustment to set temp to 106, which I tried and the heater now heats to 102. Not the best solution, but seems to work for now.

Any body know if there is a way to calibrate new thermistors on the Sovereign? It has a IQ2000 control box.

Thanks

exchange it for a new one, the temp taker is lying to the circuit board or delivering bad information correction = new temp sensor - and yes I know you put a new one in, but it happens.
Trying to be the unbaised voice of reason.
