You may have a broken thermostat wire. Disconnect the wires from the thermostat and please note what colors are hooked to which terminals. Cross the R and W wires and see if your heating system turns on. If it does not, you have a broken wire or bad connection at the heating system. If it does start, you have a bad thermostat or bad connection at the thermostat.

How do we operate and turn on it i have no manual


The left button under the temperature display lets you toggle between the heat output (high, medium and low) settings. Press the left or right side of the buttons. The center button sets the timer; press the left side of the button repeatedly to increase the run time. Press the right side to lower the length of time before the heater shuts off. The right hand button sets the desired final temp. Again it's an up/down toggle on the left and right sides of the button. Once you get to the desired temperature (in 1 degree increments), the display will return to showing the current temperature three seconds after you release the button.

Home Depot has the Use and Care manual on their product site: http://www.homedepot.com/buy/honeywell-1-500-watt-oil-filled-convection-portable-heater-hz-709.html#.UMp5GTmk5G8 .

I hope this helps.

I have two honeywell cm67ng wireless themostats and works on a timer settings. Recenently I ahve noticed that one of them is not working properly as it is not going off at the time it is supposed to go off...


Hi, I have worked with Honeywell products for years, and I have seen this type on occation. If they are wireless and on a timer that controls them, it may have a problem in the timer. See if this timer is split to operate each stat seperately. If so, find where it controls the stat that will not shut off at the correct time, and see if you see anything out of order. The stat senses the temperature and would shut this unit off when satisfied. I did find that this stat works on the basis of time and temp, and is obsolete. They are being replaced by the Honeywell CMT-927. I do believe you need to check the timer 1st to see if it is working for this side of the stat. You will need to read the instructions that should be with the timer.If the timer seems to be working fine, I would replace the stat in question as it has probably failed and will not respond to temperature or time when it gets its signal to shut down from the timer. Please keep me updated on this and we can go deeper into this and solve it.
Sincerely,
Shastalaker7

Honeywell CM67ng thermostat not working. Have tried various programmes but still seems to have mind of its own. Can we replace with something else?


The cm67ng has a feature which attempts to get the temperature to the desired point before the actual time you set. In reality this "feature" just makes the device turn on and off randomly in a really bemusing fashion. You can turn this off with the following:

1, Set timer mode to "OFF"
2, Hold down "Info i" and press "prog 3" and "prog 4" together. Display Should show a spanner in the left hand corner.
3, press "prog 2"
4, repeated press "clock +" till the characters in the display after the colon read "OP" (the number before the colon seems to vary with model).
5, Press the "temp down" button. The 1 in the right hand of the display should become a 0.
6, Press the "info i" button to save your changes.
7, Switch the mode back to auto, the timer should now behave normally.

You should note that a number of other parameters can be changed in this service mode. Some of which could probably do bad things to your central heating system if set incorrectly.. So this is at your own risk! Either way it's best to read the installation manual before attempting to change anything:

I have a Honeywell L7224U1002 aquastat and I am unsure how to turn the temperature down. The water is 180 degrees.


I fixed it by holding in the 3 puch buttons for 3 seconds and then I was able to lower the temp by using the up and down buttons.

Heater shut off but doesn't turn on by it'self


Do not touch the timer, once you do, it activates it. Set the temp. and leave the timer alone, unless you want it to shut off at a given time, 1 hr. and up. Once the timer shuts off you will have to start it manually.

Press the *power button* once to start the heater on high power, continuous run. If left at this setting, the unit will run continuously on high power (1500 watts, 12.5 amps) and will not shut off until the unit is manually turned off.
Press the *power button* again, to change to low power, continuous run, (900 watts, 7.5 amps) and will not shut off until the unit is manually turned off.

Set temperature:

Press the temp/timer button until the temperature icon blinks. Use the up and down arrows to set the desired temperature.
The temperature icon will stop blinking and the current room temperature will reappear after the desired temperature is set.

The heater will turn off and on to achieve the desired temperature.

Set timer: (auto off)

Press the timer/timer button until the timer icon blinks. The hour display will appear. The auto off icon will also appear.
Use the up and down arrow buttons to set the heater operation time between 1 and 10 hours. This function will activate once the timer icon stops blinking. The heater will automatically turn off whn the times runs out.

Set timer: (auto on)

Press the temp/timer button until the timer icon blinks. The hour display will appear. The auto on icon will also appear.
Use the up and down arrow buttons to set the heater start time between 1 and 10 hours. This function will activate once the timer icon stops blinking.
The heater will automatically turn on when time expires.

Hope this helps!
