System was not running when I arrived. I found the thermostat was set to only one stage of heat and cool instead of two stage which would match the system. I found the W-2 wire not hooked up at the thermostat as well. I fixed wiring and reprogrammed the thermostat. Heat pump kicked on, but the heat strips did not. I went through the system and checked all the wiring and separated the wiring to test voltage. Voltage from the thermostat was reading only 14 Volts. I changed out the thermostat and then the system ran in both stages for heat strips and heat pump. System is operating as it should departure.
