classic_stump asked Honeywell Thermostat with a Goodman Air Conditioner / Heat Pump How Do I Hook it Up????
I have a Honeywell Pro 4000 (TH4210D) thermostat with terminals labeled... E (emergency heat relay), Aux (auxiliary heat relay), Y (compressor contactor), G (fan relay), O (cool changeover valve), L (relay)*, R (L1 hot), B (heat changeover valve) and C (L2 common). *The L (relay) terminal is powered continuously when thermostat is set to Em Heat. The Honeywell guide also states to use either O or B terminals for changeover valve and install field jumper between E and Aux if there is no emergency heat relay. The Goodman 3 ton package unit with heat pump and 15kw heat strip has wires colored... Red (24v), Green (fan), Orange (Rev. valve), White (Heat 2nd), Brown (Heat 3rd), Yellow (cool), Blue (common). So, the main question is how do I make these connections up and what is the difference between the Auxiliary Heat Relay and the Emergency Heat Relay? Any and everyones help is greatly appreciated.
And got the following answer:
brown from unit to e...white from unit to aux...red from unit to r....green to g....yellow to y...blue to c.....do not put anything on L terminal... orange to o but if unit heats instead of cools or vice versa put orange on b...aux heat comes on while heat pump is running if it cannot heat the house without help and emergency heat turns outside unit off and just runs your electric heat....you do not need to put the jumper between e and aux...
