I always thought you needed at least 18awg solid wire for thermostats. So is there not as much voltage going to the thermostat because phone wire ranges from 22awg to 26awg, I would think the wires might not be able to handle that kind of load and melt if I was to use the 26awg.
I prefer to call my self a handyman, because it sounds better than Jack of all trades!

I personally would stick "Thermostat" wire. JMO

Telephone wire will work if the runs are short, otherwise use thermostat wire.
