I've got a Worcester Heatslave 20/25 with a ST699 controller and am thinking of something more economical to control it.
I was thinking a wireless programmable thermostat to save wiring and the need to change the controller.
So my questions, are any suggested brands?
Do i need to wire the thermostat to the boiler or can i wire it to the controller to save any potential range issues as the boiler is in the garage?
Thanks
