I have a Honeywell Chromotherm IV Plus thermostat. The current room temperature displayed is off - too low - by about 6 degrees. Is this adjustable?

It is not adjustable, sounds like the LED is going bad. Tstat has battery back up for power outages. If you slide the fan switch from auto to on does the blower motor start? If not control problem with unit.

Indoor temp is 5 degrees colder than display reads on digital thermostat


Where are you measuring the indoor temperature?
To compare it to the thermostat temperature you have to measure both temperatures at thermostat.
The thermostat will only control the temperature at the thermostat, not any where else in the room.
The room temperature depending on insulation in walls and ceiling and distance from outside wall and outside temperature, can be as high as 10° difference from outside wall to inside wall of house.
The lower the outside temperature, the greater the room difference in heating. The higher the outside temperature the greater the room difference in cooling.

My furnace has stopped working. the thermostat (Honeywell Chromotherm III) displays HOLD - AC. What does this mean? I replaced the batteries but nothing has changed.


Try to find a reset button or just change out the thermostat. I'm guessing you don't have the manual. Thats a pretty old model, I think you have to set the time and day before you can use the thermostat.

Honeywell TH8320u Vision Pro 8000 Digital keeps calling for heat


Hi,
If the thermostat is not over shooting the temperature than don't worry about it.
These thermostats are very sensitive and will turn the heat back on even before the degrees drop on the display. Often they will shut down before the display changes also. You can change the sensitivity of the thermpstat if you read the directions and change the cycles per hour to a less number. There is an installers program in there that you need to push a combiunation of buttons to get too. The instructions tell you how to do that also.

Hopefully you did not throw away the instruction manual for your t-stat.. :-)

Cooling temperature will not below 70


controllers more than likely on a memory lockout... kill the power and take the batteries out of it... leave it for 60 seconds and try again... unfortunately you are probably going to have to replace the controller, sorry

HONEYWELL CM921 ROOM THERMOSTAT


Remember the is a time and temperature controller if you want to use as an ON/OFF controller please ensure you OFF times are set to LOW temperatures for example at 8:00am I want the boiler firing to 21°C at 10:00 I want the boiler to go OFF at 5°C so ensure all so called OFF times are set to LOW temperatures.
