The following features are available on our programmable thermostat (PRT);
(Please note this thermostat is flush mounting and so requires a back box)
Upgrading your Existing Thermostat and selecting the Terminal Output
1. Firstly, check that you have at least three wires (excluding the earth) behind your existing stat. If you have, the PRT is compatible.
2. Our changeover terminal option is for those controlling a valve that needs power to open and power to close. If you are simply controlling a boiler, just select the standard model.

Q: Is this controller compatible with a Potterton boiler? The boiler is currently running off an inbuilt mechanical clock but i would like to add a controller for ease of use.
A: The Heatmiser PRT will work fine, but you need to check the wiring requirements. Our PRT requires at least 3 wires, excluding earth.
