Questions & Answers

What type of replacement battery does this unit use?

What type of replacement battery does this unit use?
Asked by: jacob
From the manual: "This thermostat contains a Lithium battery" The battery is not replaceable. You will receive no warning when the battery fails. You will need to buy a new thermostat.

Will this work with a two-wire system?

Will this work with a two-wire system?
Asked by: Ed
Yes, it is for a 2-wire system. I installed it according to instructions connecting 2 wires for auto heating control only. There is no manual on/off switch, no manual fan on/off switch like there is on a heating/cooling thermostat.

Customer Reviews

Round White Low-Voltage 24-Volt 1 Stage Heat Only Wall Thermostat is rated 3.1 out of 5 by 16.
Rated 1 out of 5 by from Innacurate reading and horrible reps at Honeywell I had my house remodeled and purchased three of these duds to get installed in my home. I have zone heating. I immediately noticed that each of them were off by 6 to 7° This can be very confusing and made me wish I never replaced my old mercury thermostats. When I called Honeywell they gave me a song and dance especially when I asked who was going to pay to install replacements. Not recommended.

Rated 4 out of 5 by from Replaced old round Honeywell Mercury switch with this unit via 2 Wires , 24V, Forced Air Natural... Replaced old round Honeywell Mercury switch with this unit via 2 Wires , 24V, Forced Air Natural Gas Furnace for 1 month now. It works exactly like the replacement one. We compares temperature to wireless digital Oregon Scientific for indoor/outdoor thermometer. This Honeywell thermostat temperature match well with our indoor digital thermometer. Note, used default/factory setting heating cycle which is forced air. Excellent installation instruction. This is no OFF switch. My old Honeywell thermostat, we can turn the dial to OFF position during summer but now we need unplug power on furnace to turn off. This is only reason that preventing me from given 5 stars rating.

Rated 4 out of 5 by from I purchased this to replace an electronic thermostat installed on an enclosed porch over the base... I purchased this to replace an electronic thermostat installed on an enclosed porch over the basement garage with central heating only. I originally installed the electronic version to eliminate an old Honeywell round mercury bulb type. The furnace is turned off or turned down to a low temp much of the time as we only heat it for special use. The electronic thermostat had very poor response at the low temperatures, sometimes taking 30 min or an hour to respond after being off all night with the room dropping to the teens or single digits. The new mechanical thermostat with a heat only stage works great. I've had it a couple weeks now. I would have preferred an on/off switch on the thermostat for this application. As it is, I have to switch off the furnace at the furnace but since it's infrequently used I can live with it.

Rated 1 out of 5 by from I bought this thermostat because it is low-voltage. My house... I bought this thermostat because it is low-voltage. My house furnace runs on a low voltage, since in 1948 they used low-voltage in homes like mine. I like the way it shows the temperature, but did not work with my gas furnace. I really thought this would work but no luck, so I went back to the old one Honeywell Economy Millivolt Non-Programmable Thermostat Model# CT33A
