Relay.

Hi,
basically a latching or bi-stable relay is a device which switches in response
to a pulse.
Say when your voltage reaches the desired value the relay can be pulsed
and it will remain at that setting until it is pulsed again,thus avoiding cycling.
Unfortunately I’m an old fossil and I have to get help with coding from my
son-in-law, they gave me a couple of hours Arduino coding as a birthday present.
Look up “Relay” in Wikipedia.
John.
