The AC works fine but the heat is either on or off - not responding to programmed settings. When I do a reset it will go through one cycle ok and then revert to on/off.
Lux thermostats are not very good in my opinion, a heat pump is an AC unit that reverses operation so if the AC works and the Heat works then it is OK as far as the refrigeration cycle which is good, replace with a better thermostat such as Honeywell , try Lux 800 # too just in case.

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

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.

Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Most thermostats use a six volt transformer for a power source, similar to a door bell, you can tell if yours does by looking at the wires that are attached to the thermostat.
The wires will be thin with just a single strand if you have these wires then you have a transformer, try and find the transformer (good luck) test it with a voltmeter if it fails the test that's it, if not, call the man. Probably it though.

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.
"PLACE A JUMPER (PIECE OF WIRE) BETWEEN Y AND W IF YOU ARE USING A HEAT PUMP WITHOUT AUXILIARY/BACKUP HEAT." if this dosnt work check the fuse in the air handler you may have blown it if you did not turn the unit off before installing.
