I have a Totaline Programmable Thermostat 0441 purchased approx 2001... The unit on the wall is completely dead...I checked the AC breaker and no difference... Is there a battery in the box? How do I get it live?

    I do not have a manual for the 0441 thermostat. How do you check for the 24v coming to the tstat on the r wire? no clue what you mean?

Hi,
The closest number that I can find to that number is a battery t-stat, so I would guess that there is a battery in there.
Pull the t-stat apart and check it out....do you have a manual for that t-stat?... it will tell you...
If no battery then the fuse for the transformer or the transformer its self may have blown...
Check for 24v coming to the t-stat on the "R" wire....

    Hi.
    To check the voltage you will need a electric meter. They can be bought at Walmart for 20 some bucks.
    Then pull the front of the t-stat off the wall and check for voltage across the "R" wire and the "C" wire or the "G" wire. The letter designations are on the subase of the t-stat....
    If there is no voltage then the problem is with the transformer or fuse in the air handler...

    I will say though that trouble shooting this type of problem can be challenging for experienced techs. so I can be very hard for the average person to be able to figure this stuff out...

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

Can't set temperature


first go turn breakers off at indoor unit or if gas turn switch or unplug for thirty seconds.should be a hold button on thermostat , set desired temperature and press hold allow five minutes to go by.listen doen anything at all happen at unit.
if nothing happens after five minutes remove sub-base from wall and at the thermostat jump with a wire the r terminal and the white terminal see if it comes on if so you got a bad thermostat most likely.

Honeywell Chronotherm III Thermostat shows time of day-AC. No heat in the 2 zones with this message.


Hello,Message AC means that there is no 24volt power to the thermostat from the unit/s it controls.Please check all switches & curcit breakers to the unit/s as there is no low voltage power to the thremostat from the transformer in the unit/s.Maybe got turned off by mistake.

I have a totaline 0441...with an EH error code I can't seem to remedy any help?


It sounds like your thermostat is stuck in EMERGENCY HEAT mode programming. To Exit,
Press the FAN button. While holding the FAN button, press the UP button for 2 seconds.
I'm also attaching a link to the manual for your thermostat.
I hope you find this information helpful to you.

AC wont kick on....


The first thing to check is your breaker box. There should be one double breaker for the air handler unit, that's the inside unit, and one double breaker for the compressor, that's the outside unit. Check both breakers. If you're not sure if they've be thrown, click them toward the outside of the breaker box (off position) and then click them toward the inside of the breaker box (on position). If the breakers are on and you still are not getting any A/C take a look at your compressor, (outside unit). If the fan is running at least you're getting power. However, your compressor down inside the unit may not be getting power or it may need to be replaced. The compressor has a start-up cap. If this cap goes bad or the wires from this cap fry or corrode away, this will also keep the compressor from starting but the fan will still run. If the fan is not running it could be caused by a faulty relay inside the compressor cabinet. This relay is supposed to open and close based on a low voltage signal from the thermostat. I believe it's roughly 24 volts. This relay switches on and off the 240 volts for the compressor and the compressor fan. Often this relay goes bad or the wires leading up to it fry. If you?re going to work on the unit yourself make sure all power is shut off. There should be a shutoff switch on the outside wall near the compressor. I?d also shut the breakers off.

I have a Carrier 38tra048340 ac 4 ton unit outside, heater in attic. Thermostat is Totaline P374-1100. Power went out than back on after a few hours due to vehicle crashing into power pole. AC was running...


Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...
