Honeywell cm67 instructions

I have a Honeywell CM67 thermostat controlling under-tile heating in my bathroom. I can't program the various time zones or turn the whole thermostat off. It is running at 36degC 24 hours a day.

SOURCE: need to find out why my honeywell rht4650d thermostat is reading "in recovery"

The problem is likely with the cooling system, not the thermostat itself. Either the message from the thermostat is not being received by the AC unit, the solenoid isn't turning on the unit or it can't cool properly.
First check that none of the wires to the thermostat are loose or broken. You'll have to take the face plate off to check. The conductors are very small wires and can break easily. Depending on the unit,there are 4-5 wires usually for a HVAC system. If a wire is loose, reconnect it (push it in or screw it down gently). If a wire is broken, strip (for screw terminals) a new section and reconnect it. Check for ice build up on the condenser coils. (That is often a sign of a refrigerant leak. You'll need a professional to fix it and recharge the unit.)
Do you hear the fan running? If you do, then the condenser is a likely culprit. If the fan isn't running, then the control board for the system may be bad. You may want a professional to check the system. If you tell them the make and model, the technician can bring the parts if it is a problem with the control board.

I hope this helps.

(We had the broken wires to our thermostat in the winter. A few years ago, a nearby lightning strike had the AC off in the summer due to the control board damage. The house reached 90 degrees while we waited for the repair.)

Many thermostats have battery backup as well as the 24 volt ac. Have you replaced the batteries to see if it fixes all of your issues at once?

I would say get a professional person to deal with it. Could mean a new thermostat. Is it battery operated? maybe the battery is low . I would replace the battery and see if that works before spending more money.

How do I set one temperature for the whole day?
To operate as a simple thermostat with one temperature throughout the day, move the slider to the MANual position. Adjust the manual temperature by pressing the TEMPerature or button. The manual temperature can be set anywhere from 5°C to 30°C in 0.5°C steps.

My heat is turning on but the fan isnt working. my honeywell thermostat is showing a flame and a blinking battery, and i know nothing about this thermostat, we just moved in . Can u help?

This is not a PC problem
Heating comes on, but sometimes it
gets too hot, sometimes too cold.
Neutral not connected
Check wiring in room thermostat. Look for a
connection to the Neutral terminal (N 2 on
the Honeywell T6060, T6160, and T6360).
Make sure that it is connected (check
If there is no neutral available, replace with a
two-wire thermostat, e.g., CT200, CM61 or
CM67. These will also offer extra energy
savings, (Without a neutral connection, the anticipator within the room thermostat does not work,
so the temperature control reduces from ± ½ºC to ±3ºC. People can feel a six degree
temperature swing. Then, if they try to adjust the room thermostat to overcome the
problem, the temperature swings become even worse.)
