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?

Can the wireless thermostat be used to switch the system on and off

Asked by: Mfrp
As well as changing the set temperature from the DT92E, it is also possible to override the heating system on or off from the DT92E. This is only possible if the ST9120C is in AUTO or ONCE Modes. If ST9120C is in CONT mode it will not be possible to switch the heating off from the DT92E. Similarly, if ST9120C is in OFF mode, it will not be possible to switch the heating on from the DT92E. If these latter overrides are required it is first necessary to change the ST9120C mode setting to AUTO or ONCE.

The Sundial RF2 Pack 1 can replace the ST9100C. They are both single channel programmers.

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.
