With System Switch in OFF, Fan Switch in HI ON and room
temperature ABOVE or BELOW setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4) and blue wire (Pin 6). You should NOT have
continuity between red wire to violet, white or yellow wires.
With System Switch in HEAT PUMP, Fan Switch in HI AUTO
and room temperature ABOVE setpoint temperature, you
should NOT have continuity between red wire to violet,
white, black yellow or blue wires. With room temperature
BELOW setpoint temperature, you should have continuity
between red wire (Pin 2) to white wire (Pin 3), black wire
(Pin 4), and blue wire (Pin 6). You should NOT have conti-
nuity between red wire to violet or yellow wires.
With System Switch in HEAT PUMP, Fan Switch in LOW
AUTO and room temperature ABOVE setpoint tempera-
ture, you should NOT have continuity between red wire to
violet, white, black, yellow or blue wires. With room tem-
perature BELOW setpoint temperature, you should have
continuity between red wire (Pin 2) to white wire (Pin 3)
and black wire (Pin 4). You should NOT have continuity
between red wire to violet, yellow or blue wires.
With System Switch in HEAT PUMP, Fan Switch in LOW
ON and room temperature ABOVE setpoint temperature,
you should have continuity between red wire (Pin 2) to black
wire (Pin 4). With room temperature BELOW setpoint tem-
perature, you should have continuity between red wire (Pin
2) to white wire (Pin 3) and black wire (Pin 4). You should
NOT have continuity from red wire to violet, yellow or blue
wires.
With System Switch in HEAT PUMP, Fan Switch in HI ON
and room temperature ABOVE setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4) and blue wire (Pin 6). You should NOT have
continuity between red wire to violet, white or yellow wires.
With room temperature BELOW setpoint temperature, you
should have continuity between red wire (Pin 2) to white
wire (Pin 3), black wire (Pin 4) and blue wire (Pin 6). You
should NOT have continuity between red wire to violet or
yellow wires.
With System Switch in AUX HEAT, Fan Switch in HI AUTO
and room temperature ABOVE setpoint temperature, you
should NOT have continuity between red wire to violet,
white, black yellow or blue wires. With room temperature
BELOW setpoint temperature, you should have continuity
between violet wire (Pin 1) and green wire. You should NOT
have continuity between red wire to violet, white, black ,
yellow or blue wires.
With System Switch in AUX HEAT, Fan Switch in LOW
AUTO and room temperature ABOVE setpoint tempera-
ture, you should NOT have continuity between red wire to
violet, white, black, yellow or blue wires. With room tem-
perature BELOW setpoint temperatures, you should have
continuity between violet wire (Pin 1) and green wire. You
should NOT have continuity between red wire to violet,

white, black, yellow or blue wires.
With System Switch in AUX HEAT, Fan Switch in LOW ON
and room temperature ABOVE setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4). You should NOT have continuity between red
wire to violet, white, yellow or blue wires. With room tem-
perature BELOW setpoint temperature, you should have
continuity between red wire (Pin 2) to black wire (Pin 4)
and between violet wire (Pin 1) to green wire. You should
NOT have continuity between red wire to violet, white, yel-
low or blue wires.
With System Switch in AUX HEAT, Fan Switch in HI ON
and room temperature ABOVE setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4) and blue wire (Pin 6). You should NOT have
continuity between red wire to violet, white or yellow wires.
With room temperature BELOW setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4) and blue wire (Pin 6) and between violet wire
(Pin 1) and green wire. You should NOT have continuity
between red wire to violet, white or yellow wires.
Switch Combinations and their Corresponding “Ac-
tive” Terminals
To check “ACTIVE” terminals, place the positive (+) lead
from the ohm meter on Pin 2 or red wire and negative (-)
lead from ohm meter to the “active” pin or wire to read
continuity.
With System Switch in AUX HEAT and room temperature
BELOW setpoint temperature, continuity will exist between
violet wire and green wire. With room temperature ABOVE
setpoint temperature, continuity will NOT exist between vio-
let and green wire.
