    Auxiliary lockout temperature

    I'm trying to learn how to adjust our heat pump's auxiliary lockout temperature. Please, any assistance would be fabulous because it seems to be set pretty high...



    thanks!

    Then you would need to post the brand and model number of your hemostat and heat pump.

    How many times must one fix something before it is fixed?

    That thermostat is not capable of locking out auxiliary heat on its own. Depending on how your system is wired there may be an outdoor thermostat installed at, near, or inside of the heat pump.

    Keep in mind that sometimes people will disconnect auxiliary heat altogether to save money.

    Sorry to confuse... I would never suggest eliminating aux heat, just suggesting that someone ahead of you may have done that if your system is not keeping up.

    You don't want to disconnect your aux heat. unless you want your house temp to drop.

    The TH6220 does not have lock out ability. So either an outdoor stat must be added. Or you need to get a thermostat that has lock out ability.

    Do you use its set back feature? If so, don't, your costing yourself money if you do.

    I would not disconnect the aux. heat either. With the temps you have in your area you will need it when the heat pump goes into defrost to keep up with the heating demand.

    As others have said you first need to know if your t-stat is capable of locking out the heat pump! If not you would need to have it replaced with one that does. In my area (which does not have the cold weather) like yours we never lockout heat pump their is no need as we have very mild winters.

    To be honest on my system I have only seen aux. heat come on twice this year and it has gotten to 27 here in Lousiana which is cold for us! Why are you trying to adjust it? Is it current set up bothering your comfort?
