I can't find my operation manual. I'm having trouble setting the temperature. What does it mean when the 'A' is displayed vs. when it isn't?

how do u turn on A button ?? at 1st it use heat up to 80..but now it only goes up to 61 on cold day ..thanks

When the A is ON the thermostat is controlling heat. Use + or - to set desired temp. When the A is OFF, the heater is simply on and heating away. If it's in a small room (10x10 say) it can easily heat that space to 90 degrees. So use the thermostat.

If the units are placed next to each other does it display the air temperature..? If not then the unit is faulty or it is not set up correctly.

I'm curious about this too. I set mine for 370 and as soon as it reaches the temperature it turns off. SO frustrating.

It starts earlier to be at set temperature. The display shows RECV during this time as it is in "Recovery" mode. Smart thermostat. This is also discussed in the instructions.

It shows actual room temp. When you push an up or down button it shows what you set it at.

There's a dial on the unit itself with different temperature settings and you turn the dial to the desired temp. and the unit maintains that temp. Some people have said they had to turn it up a little to get it to a particular temp but it turns on and off automatically.

I have never had that problem with mine. It seems to be fairly simple to operate......you turn it on, set the temperature, set the time, done. However, if you set it on the highest temp setting (which in my opinion is too hot) it will revert to the lowest temperature setting after 1 hour. I am not sure why. However, anything outside of this.....I would look into sending it back. I love this product and so do my clients.

When I switch from heat or off to 'cool', the display will show 'cool to' - which is the temperature that I had set earlier when I went through the schedule set up.

I noticed that the temp display had very subtle shading to distinguish between the heat settings. We depend on wrist dipping and a toy ducky which has a temp readout that is easier to see.

After wondering "what the heck" that when I wanted to raise the temp to 59 degrees from 54 that you click the up arrow to 59 and it reverts to 54. This is the internal temp. Wait a while for it to warm up to the selected temp. It is now running at 59 and comes on less often. Instructions were in the manual.

These t-stats are designed to come on at a certain temp and then shut off when the temp is lower than what you set it at.Let's say you set it on 90. When the temp reaches 90 it will turn the fan on. After it cools to below 90, it will turn off.I don't know what the temp differential would be though. Maybe 10 degrees? I'm not sure.

HC+ H for Hot or C for Cold CP is range of Temp... default is 2 LA is floor level temp (minimum) HA is the upper limit PU is the lag time before the device will kick on again after it shuts off. CA is temperature correction. So if you set it for 40 degrees and a seperate thermometer reads it at 42, you would enter -2 to adjust the unit. hope this helps

I don't know what you mean exactly, but sometimes my timer goes to Zero and will not change. I disconnect the power then plug it back in, then it works. To change temp, touch the up or down arrows.

Hi Sean, I guess you have found out by now, but for everybody else who follows this forum, here's the words from the manual: -------------------------------------- (1) Make sure the thermometer is turned off. (2) Press and hold down the start button (IRT 4020) or the I/O button (IRT 4520). After about 3 seconds the display will show this sequence: C / SET / F / SET ... (3) Release the start button / I/O button when the desired temperature scale is shown. There will be a short beep to confirm the new setting, then the thermometer is turned off automatically. ---------------------------------------- cheers, Ingo

The temperature and other writing only show up when the unit is first turned on or if the settings are changed while the unit is on. After a few seconds (5 maybe) this goes away so you don't have to see it.

Using the "+" and "-" buttons increase or decrease the temperature desired. On the display you will see the word "Hold" next to a button. Press that button and the temperature setting will stay at that temperature until you press the button next to "Run" (on the display) or until you change the position of the "Cool" / "Off" /"Heat" switch.

It senses temperature. You can set to come on at a below your setting, or a above settings. In other words, if you have its set at 80 degrees on the winter setting, when your furnace kicks on and the airflow reaches 80 degrees or above the fan kicks on. The opposite true for the summer mode....my opinion it works better as a booster for the furnace, but It does help some in the summer for the A/C.
