Hi All, my daughter has a honeywell CM901 room stat in her hall ( she also has one upstairs, both being controlled my two motorised valves, it is a Vailant combi boiler and the property is approx 10 years old, both programmers are hard wired.
the programmer in the hall is playing up and i have seen that the CM901 has been replaced by a later model , however is it a simple operation to replace the CM901 with a Center 7 , they both appear to do the same job, her CM901 often does not display correctly and the + and minus buttons for call for heat etc does not work correctly ,, I notice the cost of replacement for the CM901 is extortionate and the Center 7 seems a decent price, and or any other options that would work fine TIA
