if you go more than three degrees above room temp the gas heat will come on. its a pita. thats the way the stat is made. would love to see a fix.

Cannon man is correct. Also, when running on electric heat, you can gradually
keep raising the control a few degrees at a time to increase the inside temperature,
but if the outside air temperature is arround freezing, the outside A/C unit will frost up to a point where the heat pump will shut off and it appears these units have no defrost cycle like residentual units have. Then you have to heat with the gas furnace.

The ones on our 2002 DSDP do have a defrost cycle.

With the temp arrows run the temp down until the heater will not start. Then you can slide the switch over to elec and raise the thermostat to the desired level. Just keep the increase under 3 degrees so the gas doesnt kick in.
