ct33a 750 millivolt

I really like these simple to use non complicated thermostats. I would like them even better if they did not have an off position for millivolt use.

Keep it Simple

I needed a non-programmable heat only thermostat for a propane direct vent wall heater in a mountain cabin. Easy to hook up with just two wires and works fine.

Happy Home Owner

Soooooo glad to get the correct part for my ancient floor furnace. Everyone , box store Pros swore the 24V to millivolt would work. I researched what I needed on the Honeywell site, had it shipped to my home, installed it and we have a happy Warm house again. Thanks Honeywell !

Used with Natural Gas Stove

Perfect product for my Natural Gas Stove. Replaced the original on/off wall switch with this unit. Nice appearance, simple installation and appreciated the large back plate to keep the wall clean.
