I bought a new wireless thermostat yesterday and plan to fit it when it arrives.
https://www.ebay.co.uk/itm/SALUS-DI...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
I plan to remove the old thermostat which is in the hall and replace it with this one in the living room.
The system is 25 years old, the boiler is an "Ideal Mexico Super 2" and uses an external heating pump and Potterton EP2001 timer controller.
The wiring diagram on the back of the controller looks like this.
And the wiring (without the earths) looks like this.
It looks like Live is switched to terminals 3 when hot water is needed, then additionally it is switched to 4 when the CH is needed.
I was surprised to see that the pump is switched through the thermostat in the hall, was that a normal way of controlling the CH back in the day?
The new thermostat has a switching rating of 16A so should be OK hooked up in the same way I guess?
Any thoughts?
