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).

Rated 5 out of 5 by from Easy Set and forget - Automatic Switch from heat to cool Good documentation for easy install of heating and cooling control. Very simple to set up for auto switching between heat and cool. Set "heat" to turn-on temperature ( eg: 70 degrees) Set "cool" to turn-on temperature (eg: 74 degrees) Now your home will heat when temp is below 70, and cool when temp is over 74. Could not be simpler! Only restriction is that heat and cool setting must be at least 3 degrees apart (with cooling set to the higher temperature).

Replacing an old thermostat: Note the wire color and the terminal they are attached to before disconnecting them from the old thermostat. Do that, and hooking up the new thermostat is easy.

Rated 4 out of 5 by from Simple to install and even simpler to use. As an older couple who try saving money by DIY, I found this product very easy to install and to my real surprise, as advertised,even easier to to operate. No confusing programming requirements. Great for an older person like myself. Want it cool,turn on cool. Want it warm, turn on warm. Its that simple and really does work.

Rated 5 out of 5 by from What I wanted I had a programmable which was hard to read, and took forever to change when I traveled and wanted to change. Had to go through each day and time set and make changes. This is quick and easy to change heating or cooling temperatures, and has auto mode to go between heat and air IF you program it in (not the default). Only issues were that it did not work at all until batteries are installed (which concerns me when I travel for extended periods - they just say replace the battery before you go). And if I need to program again to get auto mode back for some reason, I will need to find the book (not something you can hack your way through). So this does exactly what I wanted at a very reasonable price if purchased at Home Depot (was double price at hardware stores, but they did have on the shelf instead of waiting a couple days for delivery).

Rated 5 out of 5 by from Works perfectly and very simple to operate I purchased this digital non-programable thermostat for my elderly uncle who did not want to deal with the set up of the more common programable type thermostat. This unit has a digital readout which eliminates the guesswork of setting the old slide bar type thermostat to the desired temperature. Up-down arrows set the temperature. Works for both heating and cooling. Easy to install. SImple to operate. Perfect.

Rated 4 out of 5 by from Appears to be a good product. Easy to install and to set up for other than the default operation. When it said it was backlighted, I assumed it was backlighted continuously and that the backlighting power was derived from the 24 V on the thermostat wiring. It is only backlighted for a few seconds when the light button has been depressed, powered presumably by the installed battery.
