I have my UFH configured as a Zone Valve and I use a BDR91 as my actuator. The BDR91 opens a motorised zone valve, which in turn starts the UFH pump.
I don't have a Boiler Relay because I use OpenTherm. I still have no idea if the System Parameters will affect my BDR91 Zone Valve or that is only meant for the Boiler Relay.
It would have been better if I could switch off the TPI for this BDR91, but I can't.
Hence I would like to keep that BDR91 switched ON for as long as possible each time it is switched on by TPI. The reason being, my UFH pump is an adaptive pump and ramps up slowly on power on. So each time the TPI cycle kicks in, it goes through its start up routine.
Cycle Rate is 3 per hour with a Min On Time of 1 min. What do I set this to, to keep the BDR91 ON for longer?
