Questions & Answers

will this thermostat automatically switch between heat and cooling?

I have a four wire system, the current old thermostat has to be manually switched between heat/cool. Will this one just do it automatically to keep the desired temp? or do I need to get the lesser model that has the manual switch?
Asked by: clipclop
Yes, you can program the thermostat to switch between heating and cooling to maintain a desired temperature range. To avoid possible compressor damage, do not use Auto Changeover if the outside temperature drops below 50 ºF (10 ºC).

DO YOU HAVE TO RUN ON BATTERIES OR DOES IT HOOK UP LIKE MURCURY THERMOSTATS WITH 4 WIRES

Asked by: BEAN
A single AAA battery (not included) is needed to operate the lighted display however the thermostat will still operate at the desired setting (if the battery is dead) using the 4 wires as referenced in the question. The battery is not needed to hold the setting in the event of a power outage (according to the instructions).

Deluxe Digital Non-Programmable Thermostat is rated 4.7 out of 5 by 138.

I knew the t-stat was old and could possibly be the issue. I ordered this Honeywell thermostat and it's made a huge difference! A/C is cycling much more efficiently now and I'm hoping my next electric bill will reflect the change. I like the dual temperature display (set point and actual room temp), and the back light makes it very easy to read. The instructions were very clear and made the installation "dummy-proof". I would definitely recommend it to anyone looking for a simple, quality thermostat.

The only thing I noted was the Auto change over from cool to heat was not programed from the factory and I had to call the service number to get the code to program in the auto change over function. It was an easy fix, but unusual that the stat is advertised with auto change over but does not come pre programed.

There is always someone home so we do not need a programmable unit that changes temperatures throughout the day. Installation was easy and directions were very clear. I like simple- this is it.
