Trane furnaces (XL10) use 24v ac without any problems to the thermostat.
Relay descriptions are slightly tricky as a 12v relay refers to the
coil voltage when the contacts are closed.
Some general purpose relays I use during the day have 115v AC limits
before there is an arc across the contacts. If you're using DC, they
lower the rating to 28v DC.

How much voltage support the internal relays of these thermostat??
Some buddy have work with 24 VDC on this thermostat?
Thanks
