My heating system is oil, with three hot water pumps for ground floor, first floor and hot water. These are controlled with three mains relays connected to a HM-LC-Sw4-DR 4 channel switch. The fourth channel turns the boiler on or off.
I have a temperature sensor on the water tank and that triggers the switch for the pump using a program and this works well.
I now want to program the heating pumps and my program is like this:
IF TRV1 or TRV2 or TRV3 or TRV4 or TRV5 or TRV6 or TRV7 or TRV8 (trigger when changed) has valve position >= 5% THEN turn on ground floor pump.
For the off:
IF TRV1 and TRV2 and TRV3 and TRV4 and TRV5 and TRV6 and TRV7 and TRV8 (trigger when changed) has valve position <5% THEN turn off ground floor pump
This seems very inefficient programming to me. Is it possible to say:
IF any TRV in Ground Floor Group has valve position >=5% THEN turn on ground floor pump?
Or perhaps someone could recommend where I could find documentation or examples of programming the CCU.
Thanks,
Pat
