Hi all,
I've spent hours looking at these until my eyes are approx 71 x 29mm!
I am looking for a controller for an air to water heat pump (heating only) with two relays, two sensors and can initiate and terminate a defrost cycle by temperature. I don't want to start a discussion over whether AKO is better than Carel, Elliwell etc, etc!
The relays are controlling contactors, so they don't necessarily need to be 16A.
Hoping someone can help.
Graham
