WebJan 25, 2007 · The relays have 24V ac control coils and they are fed from 120V/24V control transformers within the unit. The UV manufacturer is claiming that there is an issue with the 120V power that feeds these units. They believe the voltage is below 120V and therefore the 24V is low, which in turn is causing the relay contacts to chatter. WebDec 28, 2024 · As a workaround I can flick the relay into test mode at which point the valve serving the radiators opens; thought this at least serves as a check the relay hasn't completely failed (although the chattering probably rules out a complete failure).
