I have a CM67 that makes a loud 'tock' as the relay switches on or off. The similar unit at the Premier TravelInn I recently stayed at made a similar noise on switching but maybe a bit less echo.
Does the CM67RF or newer CM927 equivalent have silent operation at the user control since the relay switching would be in the base unit near the other heating controls?
Thanks.
