Qty:  
   - OR -   
Q: Is this compatible with a Biasi Garda M96 combi boiler?

A: Yes it is.
Q: If I replace a Honeywell 921B receiver with a Siemens REV24-RF 7-Day Wireless Programmable Thermostat unit, is the wall plate for new receiver the same or do I need a wall plate? If I need a new wall plate what is the model number?

A: You will need to replace the wallplate, a new one comes with the REV24-RF.
Q: Currently have Honeywell 921B wireless room stat and receiver. Room stat has started to develop a problem in that the digits are not displaying properly. Have read in various forums and sites that the problem described above is common to Honeywell, my unit is about 4 years old. Have wrote to Honeywell and as expected no response. Will the Honeywell CMT927 (CM927) Wireless Programmable Room Thermostat be suitable as a replacement and will I be able to use it with the existing receiver I have or will I have to replace the receiver? To ensure I don’t have to replace the unit in say 4 years or so with the same fault developing would I be better off with the, Siemens REV24-RF 7-Day Wireless Programmable Thermostat. Is the Siemens better value for money and more reliable? Is the wiring the same in terms of number wires that the Honeywell 921B uses? Will I just be able to take off the existing receiver and put this one in its place? Do you recommend any other make?

A: The CM927 will connect to your existing receiver fine. Replacing with another make such as the Siemens REV24-RF would be what I would recommend currently, although it would mean changing the receiver. The Siemens receiver will connect to the same 4 wires.
Q: Hi, I have a Honeywell Smartfit y system fitted, can you recommend a wireless controller that will work with this please. The controller is currently hard wired, 2 wires to the base box. Thanks

A: Unfortunately there is no wireless controller that will work with the Smartfit system. You will need to replace the whole system including motorised valves to have a wireless control.
Q: I already have the controller for CM927 but need a new receiver, can I buy one of these separately or do I need to buy the whole thing again??

A: Yes you can buy the receiver. HCO Code 09A03
