sunvic thermostat / siemens programmer

[goodatnothing]

please, could anyone help re wiring my sunvic tlx 4101 stat to a siemens rwb9 programmer thanks.

siemens has (N) (L) (1)HWOFF. (2)CHOFF. (3)HWON. (4)CHON

sunvic (1) DEM (2)COM (3)SAT

what colour wires are they, where if all of three wires do they go to on the programmer.

All connectons should be made via the wiring centre and not directly to the programmer.

If you have removed an old room thermostat then it should be fairly obvious, the only complication being if the old one was fitted with an anticipator device.

Anyway, COM (2) should be connected to the CH ON, DEM (1) should be connected to the white wire of your motorised valve.

But maybe you should think about getting someone in to wire it for you to be on the safe side
