Honeywell vision pro, fan always on? and True Steam problem


Hi
I have a Vision Pro 8000: TH8320U1008
True Steam HM509W1005
Variable speed furnace
Heat Pump Armstrong

Question#1: The Fan is always on: the Green Wire from the thermostat is always with 24 Volts. Even with the Fan off in the thermostat.


Question#2: How to wire the True Steam from Honeywell?
I used Page 15 from this link:
http://customer.honeywell.com/techli...69-2036EFS.pdf
Dip 4-5 on
The problem: if I disconnect the GF Wire at the True steam (Fan input from the termostat) the True Steam continue to steam. Why??



For reference here is my wire:
Thermostat G: Green wire to True Steam GT (Fan Input from Thermostat)
Thermostat Y2: Black wire to Heat pump black wire and to Furnace blue wire
Thermostat Aux: White wire to Heat pump white wire and to furnace white wire
Thermostat RC jump with R: Red wire to Humidifier RT and to Heat pump and Furnace red wire
Thermostat O/B: Orange wire to Orange heat pump and furnace orange wire

Thermostat Y: Yellow wire to Heat pump and furnace yellow wire
Thermostat C: Blue wire to Humidifier C, heat pump and furnace Blue wire




At the True Steam:
24v: nothing
24v: nothing
Hum: Mecanical humidistat

Hum: Mecanical humidistat
C: Blue wire from Thermostate, heat pump and Furnace
GT: Green Wire from Thermostat Fan output
R and RT jumper + Red wire from Thermostate, Heat pump and furnace
GF:wire go to Green wire from the furnace (fan)


Any help is welcome


Thank you

Disconnect the G wire from the thermostat....The Blower Motor should stop work.

First you need to find the 24V wire, Call for cooling wire ....you already know G (Fan).

If you connect these 3 wires you should have cold and fan on.

Check your program settings. if the program settings have the fan set to on. It will run the fan no matter what you set it to on the main display.
