Programmable Thermostat

Heat / auto

But how do I set thermostat so the furnace turns on when the temperature dr ops below 82°F?

Why can you just answer my question?

The manual doesn't tell me how to set the thermostat so the furnace turns o n when the temperature drops below 82°F?

Hardwire it to always on. 82 may be the upper limit. When it hits 90 open a window.

To manually override the program settings, see page 6 of user manual here:

drops below 82°F?

I smell a troll.

s below 82°F.? What positions should the MODE and the FAN switches be moved to?

Do you want me to read you the manual, or will this link suffice?

Pages 10 through 15 show how to set the temperature. The "heat setpoint" is the one you're interested in.

Dang, this is a complicated thermostat. Did you really pay the suggested retail price of $83 for yours? This one probably would have done you just fine for about 20 bucks:

I'm sympathetic to your plight (despite my snarky remark about reading you the manual). My mother had me program hers to always stay at the same temperature. It's pointless for her HVAC guy to have installed a programmable.

I just want a thermostat that will keep me warm in the winter and cool in the summer

Set the mode switch at the bottom left to "heat" Set the fan switch at the bottom right to "auto" Set the program switch on the right hand side to "off", that's the middle position. Use the up and down arrow buttons to set the desired temp.

In summer just change the mode switch at the bottom left to "cool"
