Afternoon Gents
I am hoping you may be able to help me out.
I want to replace my existing damaged Drayton RTS1 Room Thermostat with a Drayton Digistat +. The existing thermostat has three connections coming from the 280 RSF boiler into its base plate/terminal block, these being:
Terminal N – Blue Cable
Terminal L – Brown Cable
Terminal 3 (Call) – Yellow/Green Cable (rapped in red insulating tape).
The proposed Digistat + unit has a set of four terminals, these being:
Terminal 1 – Off (Heating satisfied of call for cooling)
Terminal 2 – On (Call for heat)
Terminal 3 – Com (Common)
Terminal 4 – N (Not required)
As the new thermostat only requires a two wire connection, am I right in thinking that I need to connect the brown cable from the boiler to the COM terminal of the thermostat, connect the yellow/green cable to the On (Call for Heat) terminal of the thermostat and to disconnect and isolate the blue cable at both ends. Or is this a waste of time due to the age of the boiler (installed about 11 years ago) and should I replace the damaged thermostat like for like.
Any help would greatly appreciated.
