I have a CH/HW system with 6 stats, some of which are programmable all at £240V. They control my Oil Fired boiler System.
I am having an ASHP fitted which I want to control with the existing 240V timer/stat control system.
The ASHP has a pair of terminals (Currently looped) as part of its 12V system specified for connection to "Timer/stat"
I think that I ought to be able to connect a Relay that activates the 12V control circuit when there is a demand from the existing system.
My intention is to manually switch between boiler & ASHP depending on weather conditions.
Which Relay would be appropriate?
I hope someone can help
