Hi,
I recently purchased a Nest Learning Thermostat for my Potterton Powermax HE boiler. Nicely installed by a Nest Pro but was told that the hot water control is only internal despite there being wiring connections for hot water (brown wire). I’m sure it’s just due to it being an old system but wondered if there was any chance it could still be connected to the heat link so I can remotely programme the hot water?
