Honeywell VisionPro IAQ YTH9421C1002 Wiring Help


I need help wiring a Honeywell VisionPro IAQ Programmable MultiStage Thermostat with Total Home Comfort Control YTH9421C1002 I have a heat pump and furnace so in total there are 3 stages of heat One Heat Pump Two Gas Furnace - Low Fire Three Gas Furnace - High Fire One stage for cool Can you help me set these up on the Equipment Interface Module.. Here is My system : Goodman SSZI60361 Heat Pump Goodman GMV950704CX 95% 2-stage, Variable Speed furnace Goodman CAPF4961C6 Goodman TX3N-4 Expansion Valve Honeywell C7089U1006 Outdoor Temperature Sensor‏ Sorry for the delay, our internet been acting up all evening here. Wire hook up. EMI--------Fur---------HP R's----------R-----------R C------------C-----------C O/B---------O-----------O Aux--------W1----------W2 Aux2-------W2 Y------------Y-----------Y G------------G Jumper from R's to DHUM1 DHUM2 wire to DHUM on furnace board. Make sure set STAT to TWO. Cut CUT FOR DHUM wire. Let me know if you want me to go over the set up menu of the stat. Thank you, I do not have a dehumidifier, does the furnace act as one? If not do I still cut the dhum wire and the other dhum connections? Thanks Yes, the furnace acts like one. I set the dehumid level of the stat to 45-50%. When the homes humidity is above that set point, it will slow down your blower to allow the coil get colder to remove the humidity out of the air. If the homes humidity goes 5% over set point the stat may over cool the house up to 3˚ below set point. T-stat's set up menu. 160-0 (I do not suggest using program mode for HP system, they are best to set it and forget it) 172-2 173-0 174-1 176-2 180-0 190-0 200-1 210-0 220-2 250-2 260-3 280-1 300- up to you. 340-0 342-1 345-2 346-0 347-2 350-20 (If HP cycles off, you may be able to drop it down to 15. If you find this you are feeling Cold can bring it back up to 20) 360-40 365-0 370-1 372- You have a humidifier? 379-1 383-3 400- Do you have an air exchanger? Furnace dipswitch settings. 1-off 2-on 3-on 4-off 5-on 6-on 7 8 be set depending on temp rise. On the Heat Pump I have 5 wires to connect to and 5 wires on the schematic they are: R, W2, O, Y, C There is no green wire in the low voltage connection box on the heat pump.. Do I need the sixth wire ? and if so, What do I connect it to ?? Thanks, JonnyD My bad about the G wire. Nothing going outside for that.
