If you have any problems with the registration process or your account login, please. First off, many thanks in advance for ANY assistance. My family has purchased a new home that has a 4 zone Carrier Comfort Zone 1. The thermostat is the original 'rotary dial' digital model. PROBLEM = The thermostat wont allow a heat setting between 66 and 60. It will let us set 66.67.68.69 and up, or 60. But nothing between 60 and 66.
From reading the manual, it seems it MAY be related to the 'zone of comfort' 14 degree spread, but cant seem to be able to change it. Really need to be able to set to 64 or so as heating to 66 all winter will be bad for the bills.
If there is no answer. Does anyone know if the new Carrier Thermostats (infinti / etc) will work with the older systems?
THANK YOU IN ADVANCE! I believe you will need to set the minimum temperature using the rotary switch position set to S-3 before programming the thermostat. Check to see what it is set on. I have attached a more comprehensive document that may help you. The Maximum Temperature is only used for cooling. It is set by selecting Rotary Switch Position S-2. The Maximum Temperature setting is used when a temperature above the 14° span is selected.
If the Cooling Base Temperature is set to 68°F and the cooling setpoint is 82°F, any attempt to raise the cooling setpoint will select the Maximum Temperature. The Minimum Temperature is only used for heating. It is set by selecting Rotary Switch Position S-3. The Minimum Temperature setting is used when a temperature below the 14 ° span is selected.
If the Heating Base Temperature is set to 54°F, any attempt to lower the heating setpoint below 54°F will select the Minimum Temperature. Both the Maximum and Minimum Temperatures are intended for use with schedules or setpoints which are extreme compared to normal building temperatures. Thanks for the reply.
And I researched and it is letting me change the minimum heat point. If I set the minimum to 58, it will drop from 66 to 58. If I set the minimum to 62, it will drop from 66 to 62.
Seems like somehow the 'span' is set to 66 to 80 and there is NOTHING that is letting me change that piece. The '9' setting says it will show the span (high and low) but all it shows is 'dashes' in the top left and lower right. And when I press the up or down to change, nothing:-( Any ideas??? Thanks again for the help!!! There is a 14 degree range as a previous poster stated. This thermostat is pushing 19 years old or at least 15. It probably is beginning to fail.
You may not be able to set the themostat properly because some of the functions are failing. I am assisting a friend with the same system. The relays in the controller, not the thermostat have gone bad and recently replaced it. The parts for the comfort zone are very difficult to find if not impossible. I'm not familiar enough with the thermostat to know if there is a replacement. I have heard that the newer thermostats are not compatible, but don't take my word for that, if you find out different I would like to know.

You may want to try the vacation mode to see if that meets your required temperature settings Comfort Zone also has one additional set of temperature settings. These are the Vacation Setpoints.
Comfort Zone Ii Manual Mode
The Vacation Setpoints are the heating and cooling setpoints to be used in all 4 zones whenever the Four Zone Controller rotary switch is turned to 'Vacation.' The Vacation option is used to place the entire building in setback during long unoccupied periods without the danger of freezing or extreme heat/humidity. This sounds like you would not be able to set zones for different temperatures.
Latest update. Apparently the thermostat has a 'short' and I can either live with never setting a heat temp between 66 and 60. Replacing the thermostat (and possibly panel).
OR find an old rotary dial Comfort Zone thermostat. Does anyone know about the backward compatability in terms of using a newer Comfort Zone thermostat. THIS SUCKS.:-( - Appreciate any helpto the best of my knowledge the newer thermostats are backwards compatible.
May i ask if you are using a carrier dealer to figure this out? Quick Navigation. Site Areas.
