Should the "cool setpoint" temperature be higher than the "heat
setpoint" temperature?
Hi,
Easy to remember this way; cool down to, heat upto the set temp.

Hmmm,
My power and NG cost is fixed for long term. Any way is there any one
who does not know that? One reason using programmable 'stat is to save
energy. I use wireless 'stat. In summer, it moves to upstairs, in
winter, it relocates to downstairs.
