Honeywell Chronotherm III Lowest temperature setting is 45F Any way of getting it lower thanks

    We've got a 40 by 100, two story (basement plus 1st floor sanctuary) religious structure. Nowadays it's only used for services once every other week. (It used to be a lot more...)

    The heating system is a forced air natural gas furnace, with the thermostat upstairs and no zoning.
    Currently I kick it to 45 degrees and raise it once every two weeks. I'd like to lower it even further.

    The only wet plumbing is at a corner of the basement where the pipes enter a small utility room (furnace and gas water heater). Next to that is a kitchen and a bathroom. All pipes are below grand level.

    Eventually I'd love to just heat that area and let the rest of the facility cool down to ambient (well, probably no lower than 20 degrees or so). But for now the extra five degrees (main thermostat from 45 -> 40) would be a start.

If you are successful in setting it lower , you will end up with frozen pipes and large plumbing bills. Since the internal walls of a building can be as much as 20 degrees lower, that the room.
And the location of the thermostat, may be even warmer, that that of the areas where the plumbing is.
Now what is your reason for wanting the thermostat operate at a lower temperature?

On many thermostats you need to take the cooling temperature up before you can set the heating temperature need to maintain a 2 of degree deadband between the two settings...

My honeywell chronotherm III says -AC any ideas

The problem is your 24v power source. I am unsure as to why you put "other than power source or batteries". If you did indeed check that your thermostat is receiving 24v, then I would say that you have a bad thermostat. Hope this helps

I have a honeywell III chronotherm thermostat /It won't turn on the heat or the air conditioning when turned to those settings, but it sometimes will when turned to "auto". The batteries seem fine, no...

it sounds like it is time to repalce the stat, auto is set to allow the fan to run only when the heat or a/c is on, the switch for heat and cool will select either, and the temperature lever should allow contact for the bulbs to bring on the desired component. there are no replaceable parts on a thermostat, or I would try to walk you through replaceing them. good luck.. I prefer the honeywell vision pro or the white rodgers 9500 series stats
