Check the drain line for a float switch with 2 wires. DO NOT LEAVE SWITCH OUT. Must clear the drain with shopvac or compressed air.

How to I control this ridiculous thermostat (Totaline P310-0210) Just moved into this house and no manual, if I press buttons it says stage 1 or stage 2, I/m freezing...someone help!!

Hello Stephanie Sakata,

I found 2 (two) "TOTALINE" manuals...

These little beauties all work pretty much the same...

Put the slide switch in HEAT MODE...

Push the "HOLD".. (which keeps any/all
clocks/gadgets and BACK-SETS off)...

and ADJUST THE TEMPERATURE where you want it...

Read these manuals (

Thermostat Totaline P7470100

It's probably the liquid crystal has a crack and is flowing inside the glass. It can only be repaired with a new display.

Why not contact Totaline directly and see what they can offer?

I have no idea how to use my totaline digital thermostat,

Totaline is a brand name of the Carrier Corporation. Go on and research the model of your thermostat. User manuals are available.

Totaline power

I don't know anything about your particular T-stat, but power comes from the transformer and there should be a 3 amp fuse next to the transformer. They're both located in the air handler (where the fan and evaporator coil Is).

I tried to turn on my air coditioning today for the first time this year and my Totaline Themostat P474-1050 won't turn on. Worked fine during the winter and last summer.

the thermostat is powered by the unit or batteries if batteries they may be dead if the unit you need to check fuses outside at unit or reset breaker outside depending on age of installation
