Enclosure for 2 Relay Switches

I want to be able to see if the switch is operating (with the light showing when on). I've had trouble thinking that the Heat Pump wasn't working and complained to the manufacturer; but then found it was actually my relay that had stopped functioning. So one with a transparent door would be...

Enclosure for 2 Relay Switches

I want to see the led lights to confirm the relay is on (or off) so if the Heat Pump is not working I know it is not the switch that is faulty (not operating). I have looked at many catalogues and seen nothing that I made for the purpose

Enclosure for 2 Relay Switches

I have 2 relay switches to control switching between my Air Source Heat Pump and my Oil fired boiler. I want to mount them on rail within an enclosure similar to a Consumer unit housing. I am struggling to find a neat solution. Any ideas?

Control of Air Source Heat Pump

Thanks again I will make sure about the frost protection point Re pumps: We will have separate pump and think that check valves on each heat source will do the trick. They may even allow both heat sources/pumps to run together; but that is for the post-operational experimental phase

Control of Air Source Heat Pump

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...
