UFH strange behaviour
Posted: Mon Nov 30, 2020 10:21 am
I've added the HCC80R and also I have T87RF2033 as the room thermostat (from evohomeshop). I use the OpenTherm bridge.
Everything is connected and working fine. However, when the temperature is within 0.5C of the set-point the boiler is throttled down by evohome and opentherm. Just like it would with a radiator system when in steady state just topping up the system.
However, it closes the actuators and switches off the UFH pump when it is 0.5C off the setpoint while the boiler is still running throttled. This sees strange behaviour as why would you keep the boiler running if all the actuators have been closed and the UFH pump switched off.
