Look at the instuction booklet (or on the T-stat board) for a switch for the reversing valve.
Some systems reversing valves are in cooling mode when energised, some are in cooling mode when NOT energised.
You are looking for the switch (Usually very tiny, or a different jumper setting) that will change the position of the reversing valve when calling for heat/AC.
This is not a switch like the typical "ON OFF AUTO, HEAT COOL EMG HT switches. It will be on the board itself or the back of the T-stat.

You have a heat pump. You need a thermostat for "Heat pump with Electric back-up heat". Make sure the 'stat has either an "aux" (auxilliary heat) or an "E"(Emergency heat) terminal. The wiring instructions will be provided with the thermostat.

Hi, If indeed you do have a heat pump, there wouldn't be any gas involved as a heat pump runs on freon with a reversing valve and heat strips for aux and emerg. heat. For gas electric operation thermostat terminals are rc to rh with factory jumper. Red wire to either.W to W for Heat, Y to Y for cooling G to G for Fan. If you have a blue, you wont need it unless this is a commercial stat useing a common for the Led lights on the stat. The unit will get its 24volts through R terminal in combination with y,w,and,g. Cant be a heat-pump if you have a gas furnace.Wrong t-stat. You need a gas /elect stat. And on a 24volt programmable t-stat, the batterys are used for the program only.If the batterys die, than you will loose the program on most residential stats. On commercial stats with the common in play, when batters die the stat defaults back to the factory settings.If you had a Lennox heat-pump stat on a gas/elect unit, you need to change it. Someone was using what they had on hand. Let me know if this has helped you.I will be here if you need me. Sincerely,
