JJ , we are talking about clicking and not voltages.

read the post I replied to. The guy asked why thermostats might use
relays
and not solid state switches. High voltage/current thermostats might be
one
place where you can't stick a powerful enough solid state switch.

This is Turtle.

No city or Area code of any Kind let's you use line voltage on
residentiual
equipment. Low end RThermostat equipment used Phycial relays and High end
Thermostat stuff uses Solid State.

what about thermostats for baseboard electric heaters? Those are 240V
like this one http://www.aubetech.com/english/apec2.html#TH110
240V, relay, digital.
