Rated 4 out of 5 by from thermostat control We have a problem with the thermostat. If we set the temperature at say 25 then the boiler works heating the house until it reaches that temp. However when the temp is reached it switches itself off we find that when the temperature drops it does not switch itself back and so the house becomes cold and we have to start all over again.Surely if the temp drops below the required temp heat then it should switch itself on again automatically?

should the thermostat switch itself back on when the temp drops below the required level

Asked by: Ray36
The thermostat will only operate if the programmer is in an on mode. The thermostat use TPI control and will calculate how often it needs to fire the boiler to achieve and maintain the set point.
