SOURCE: MY HEAT PUMP SYSTEM WILL NOT WORK IN EMERGENCY MODE
the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.

There should be electric heat strips in the airhandler.
They automatically come on when the unit goes into defrost, the thermostat is turned up more than 7 degrees over the indoor temp or if the outdoor temp is just so cold the HP cannot keep up.
Tat is your auxillary or emergency heat.
What does the new t-stats installers booklet say that the 0170 function and #2 #7 options are for?
If it is for gas vs elec heat then set it on the elec option.
The difference is that in gas heat systems the blower comes on a few min AFTER the furnace fires up to allow the heat exchanger to get hot.
In an electric furnace the blower has to come on emediatly because the heat strips get hot emediatly and if the blower is delayed the system will shut of in high temp overload.

Do you have gas or electric heat. If you have gas then you do not have a heat pump. You should in most cases have a red,yellow, white, and green wires coming to the thermostat. R should go to rc/rh G should go to green Y should go to Y and w should go to W. Also the switches on back should be switched to non heat pump and gas rather than electric. Hope this helps.

You may and an anolog stat and the old one was digital if so it won't work. Digital sends info to system anolog is just a set of points open or closed. Digital can carry tons of info to system like a computer. Like comparing a computer to a rock. Sorry but you need to go back to proper type stat.
