Thermostat wire codes do not match
I'm attempting to install a Honeywell programable thrmostat to replace my old mercury white rogers t stat.
When I pull the old T stat it has 4 wires coded as follows
The new thermostat mentions RH and W wires but I'm nit sure what the T1 and T wires are for. My guess is a timer as the old TStat had a timer and did not use batteries. I'm tempted to just cap them and go on with the install.
Anyone have any ideas?
If this is just "heat only" you are correct. Use RH and W and cap off the others.
It is heat only. I capped them right after I posted and got the new tstat working
Thanks for the info
