Wow...........I was beginning to question my knowledge of electric but then i did the math. As stated Ohm's law and between 210-240 volts 41.66-47.61 amp difference.
I read his first post on that and let it go. And as usual you guys would not let it ride. Constant policing here. But thats a good thing. Keep everyone in check. :angel:
Good job westval !
If there is enough amperage to the air handler you could let the thermostat use 10KW for AUX heat and use the other 5KW for defrost. Most air handlers just need a simple wiring change to set them up that way, connect W1 to the thermostat, W2 to the white/defrost from the condenser. If the heat pump can't keep up then only 10KW of heat would be added instead of the full 15KW. If the temp dips too much with only 5KW in defrost the thermostat will bring on the 10KW aux heat for a total of 15KW. Wiring this way has some potential to save some $$$ in defrost at the expense of cooler air from the registers.
