Hello everyone,
I want to connect type 698 ( Thermostat, Tess library) with type 505a (Water-Air heat pump, Tess library) in order my heat pump (type 505) not to work all the time but only when temperature of my building drops below 20 C. I want to heat my building (type 56). How can I do that?
Thanks in advance,
Asimakis, Athens-Greece
