Take control of your home or office heating with our wireless central heating thermostat.

Maintain a comfortable temperature all of the time.
Save energy by allowing your heating to turn off and cool the house down when your are not it.
Thermostat can be wall mounted or freestanding therefore allowing you to move the to thermostat around to the room you're occupying.
Ignore the myth that it is cheaper to leave your heating on then having it cycle on/off. It is a proven fact that your home/ office will use more gas/ electricity if your keep your heating on all of the time. Heating loss through walls or roofs increases the higher the temperatures difference between inside and out.

Connection to the boiler
Firstly, if you have a programmer/ heating timer built into the boiler, then this must be set to permanently on so that it will not interfere with the new programmer built into this new wireless thermostat.
The signal receiver box is placed on the wall next to or below the boiler. This box is wired directly to the boiler, but it will communicate wirelessly with the wall mounted thermostat in the occupier area of the home/ office.
Most boilers which have not had a heating thermostat fitted in the past will have a wire loop between two terminals close to where the electric supply cable is attached to the boiler. This loop may have connection names for example, Lc and Lr or similar but you will need to check in your boiler manual or with the boiler manufacturer. One of these terminals will normally be a permanent live and the other a live return from the thermostat wall receiver.
The wall receiver then simply acts as a switch so that when that when the wall thermostat tells the heating to come on, the receiver powers the live return an tells the boiler to come on.
If in doubt, consult with a qualified electrician.
Thermostat requires two AA 1.5v Batteries (not included)
