Replacing Switchmaster 400 control?

[Simon C]

Hi Everyone,

I've got a Central Heating Systems fed by a potterton back boiler, which is controlled by a Switchmaster 400 electro / mechanical switch. The only way to control the heat output is a dial on the boiler than can change the heat output from 1-6. 1 being a little cool, 1.5 being just right and 6 being absolutely boiling!!!!

I'd like to change this Switch to a more modern electronic type, as well as adding some form of room thermostat to the setup. I thought I could mount the thermostat next to the timer to get some form of main control of the heat output.

Is it possible for me to change my system in this manner? I've seen various direct replacements for the Switchmaster, but nothing that includes or supports a thermostat.

Any help would be appreciated!

Thanks

Simon

Probably because the programmer isn't often in the best place for the thermostat. And also that the wiring may not allow it to be fitted there - it controls the pump, rather than the boiler.

Wireless stats are available. The base unit goes where is convenient, wiring wise, and the thermostat in the best place for sensing the house temperature.
