Comlicated Hvac

[Guest biscowar]

Problem to solve: I have a very old heating sistem. There is only one thermostat controlling a pump, and when thermostat go to on all the fan coli start to work. Now i want to use fibaro to make the fancoil independent, using a remote switch FGS211 and EVERSPRING ST814. This is simple but i have to turn on and off the pump. So when 1 heater start the pump have to be put in on, when another heater start the pump have to stay in on, but whe one of the heater go to off and 1 is stil in on the pump have to stay on.

If temp reached -> turn off fan coil -> else stay on

If ALL fan coil temp is reached -> turn off pump -> else stay on

How to solve?

Hi biscowar,

I am new at HC2 and also at Automation but has I am dedicating a considerable amount of hours (mainly during long nights

Have you tried using variables + scenes?

HC2 lets you under the scope of a scene instantiate a variable and also re-use it for decisions.

Why don't you generate a variable per heater and evaluate when to put the pump off based on those two?

Does this help?

Regards,

Miguel
