Could anyone please help me and advise
I am having my existing boiler replaced with a worcester greenstar 30RI. My existing system is a pressurized system with a Glowworm 70FF boiler as the heat source which is on its way out. I need to alter my existing CH system to be 2 zones,(1 for a disabled family member in their living space and the other zone for the rest of the house). I intend to use the Honeywell DT92E wireless stats for temp control in those zones and I require advice on which programmer is most suitable to link them with, remembering that as well as the 2 CH zones there will also be the Hot water to control. Will the Honeywell STC9520C be the answer or is there an alternative programmer that will meet my needs. The only control I have at present for my CH is via thermostat valves on all the radiators with no room stats and a programmer that selects either or both CH and hot water.
