Underfloor heating controls - odd behaviour

Hi

I have a three zone wet underfloor heating system. Each actuator on the manifold is controlled by the HCC80 with Y87RFs in each zone as the sensors.

I’ve noticed some strange behaviour today. In System Summary on the EvoHome controller one of the zones is showing a demand of 63% yet the zone temperature is several degrees above the set point. However the zone isn’t showing as active on the HCC80.

Anyone have any ideas what’s going on here?

Thanks!

NO or NC switch set the wrong way? Faulty thermal actuator?
