So I have put in a Burnham K2 120 with Sage 2.2 and there is a Sage zone pump control.
There is two thermostats, so two zones and 3 zone pumps ( two are on the same zone but wire into the controller 1, 2 and 3).
My question is this, I want to control pump 1 and 2 on the first thermostat and control pump 1, 2 and 3 with thermostat 2.
Looking for ideas on how to make that work?
The reason for doing it this way is the 3rd pump is for a small zone and I want to activate the other zone so there is no short cycle of the system.
