Re: Thermostat Install Help I assume you have a single stage heat pump with 2 stages of supplemental heat. If you in fact have a system with 2 stages of supplemental heat and want to maintain that functionality, you have the wrong T'stat.
While you could wire only to W2, you would loose the staging functionality and possibly some comfort. With all the supplemental heat coming on at once, under moderately cold conditions, the inside temp could overshoot. This will not be comfortable and will waste energy.
Depending on the nature of the supplemental heat, there may be a setting in your furnace where the second stage can be programmed to kick in 10 minutes or so after the W1 call. In this case you only would need to wire to the W1 connection. This may help comfort and overshoot.
If it were my choice for the system I assume you have, I would install a Honeywell TH8320U1008 or TH8321U1006 which adds humidity control
The difference between genius and stupidity is that genius has its limits.
