I have an existing Ferroli boiler which has the small round programmer (1 day only) with a mechanical room thermostat. Is it possible to replace the room thermostat with a digital programmable thermostat to enable better control of the boiler. In essence I want to set the boiler to be on permanently and then use the digital programmable thermostat to control via temperature the need for heat. I hope this will enable me to gain 7 day control of the boiler.
Question is, is this possible and do the digital programmable thermostats work as a switch with a single 2 core wire similar to mechanical thermostats. I am looking at the 3 models below:
Danfoss TP7000
Drayton Digistat 22084
Honeywell CMT907
Any comments or pitfalls gratefully received.
