I'm was not able to get my honeywell zone control board to activate it's emergency heat without using their EMERGENCY HEAT switch. My thermostat has an emergency heat mode and it works fine, so I don't want the home owner to have to go to the furnace to place the system in EM heat. I had 27 volts going to the W1/E thermostat terminal blocks on the control board but the W1/E on the equiptment terminal block did not respond. I was suposed to be 27 volts. But the heat pump just kept running (Y1 had 27 volts and never shut off in EM heat) By the way Trane zoning is not perfect but it's alot better than this honeywell!
