Hi,
Have a Y plan honeywell system, with a ST699 controller.
Am considering replacement with one of these - a combined controller and wireless room stat (dont have a room stat currently).
http://www.discountedheating.co.uk/...l_Radio_Frequency_Heating_Control_Pack_2.html
It says it is compatible with many industry standard backplates.. anyone know if it will plug onto a ST699 backplate please?
Thanks!
EDIT: "a wireless enabled programmer the ST9420C and a wireless thermostat the DT92E"
