CH Lifestyle Wiring Centre / Thermostat Question Help

10051550 · 22 Sep 2012

I have a Lifestyle Wiring Centre MK1 for my central heating and a Salus thermostat ( volt free contacts ) across terminals 2 and 3 to switch on heating.

I need to have another thermostat upstairs in the house, can I simply connect another thermostat with volt free contacts in to connections 2 and 3 - effective in parallel with the existing thermostat ?

What little I know about sparks suggests this should work

Thanks in advance for all replies

should work fine

that's great - any recommendations for a budget volt free thermostat - I've found a few but the boiler seems to suggest I need 10 A contacts ?

Are you wanting the system to work so if it's cold either upstairs or downstairs the heating comes on?

This will of course mean that even if it's red hot upstairs, and cold downstairs or vice versa the heating will keep running.

If that's what you want, then wire it in as you suggest. If you want upstairs and downstairs to be controlled seperately, then you'll need a plumber to install you an additional zone valve, and this will require wiring to the new thermostat independant of the existing one.

Any themostat will be ok for a normal boiler, as it should be powered from a 3A fuse at the boiler spur anyway.

Yep that's exactly what I need

The problem is my log burner heats the lounge two degrees under hell then it's like the North Pole upstairs

We don't use the burner all the time , so a second thermostat seems the solution

Your problem is that you have the thermostat in a room heated by something not controlled by the thermostat. You'd have similar dysfunctional heating if you put the thermostat outside, or above the cooker hob in the kitchen.

Putting aside whether different zones would be preferable, the simplest answer surely is to move the thermostat somewhere sensible and put TRVs on the rads in the living room so that they don't come on when you're running the woodburner.

It might , so TRV's would stop the rads on the lounge when log burner is on - thanks for the tip
