With the room temperature below the setpoint tempera-
ture, continuity should exist between
RC
to
G
. No continu-
ity should exist between
RC
to
Y, RC
to
H
and
RH
to
W
.
With the FAN switches in ON and HI and the room tem-
perature above the setpoint temperature, continuity should
exist between
RC
to
G
and
RC
to
Y
and
RC
to
H
. There
should be no continuity between
RH
and
W
. With room
temperature below setpoint temperature, continuity should
exist between
RC
to
G
and
RC
to
H;
and no continuity
should exist between
RC
to
Y
and
RH
to
W
.
With the SYSTEM switch to OFF and FAN switches to
AUTO and HI or LOW and room temperature
above or
below
setpoint temperature, no continuity should exist be-
tween
RC
to
G, RC
to
Y, RC
to
H
and
RH
to
W
. With FAN
switches to ON and LOW and room temperature above or
below setpoint temperature, continuity should exist between
RC
to
G
and no continuity between
RC
to
Y, RC
to
H
and
RH
to
W
. With FAN switches to ON and HI and room tem-
perature above or below setpoint temperature. Continuity
should exist between
RC
to
G
and
RC
to
H
and
RH
to
W
.
With FAN switches to ON and HI and room temperature
above or below setpoint temperature. Continuity should
exist between
RC
and
G
and
RC
to
H
and no continuity
between
RC
to
Y
and
RH
to
W
.
With the SYSTEM switch HEAT position, FAN switches to
AUTO and HI or LOW positions, and room temperature
above setpoint temperature. No continuity would exist be-
tween
RC
to
G, RC
to
Y, RC
to
H
and
RH
to
W.
With room
temperature below setpoint temperature continuity would
exist between
RC
to
G,
RC
to
Y
and
RC
to
H
. With FAN
switches to ON and LOW and room temperature above
setpoint temperature, continuity would exist between
RC
to
Y, RC
to
H
, and
RH
to
W
. With room temperature below
setpoint temperature, continuity should exist between
RC
to
G
and
RH
to
W
. No continuity would exist between
RC
to
Y
and
RC
to
H
. With FAN switches to ON and HI and room
temperature above setpoint temperature, continuity should
exist between
RC
to
G
and
RC
to
H
and no continuity be-
tween
RC
to
Y
and
RH
to
W
. With room temperature below
setpoint temperature, continuity should exist between
RC
to
G
,
RC
to
H
and
RH
to
W
. No continuity would exist be-
tween
RC
to
Y
.
To check ACTIVE (ON) terminals, place on lead from ohm
meter to
RC
or
RH
terminal and the other lead from the
meter to the ACTIVE terminal.
With room temperature BELOW setpoint temperature, you
should NOT have continuity between red wire to violet,
white, black, yellow or blue wires.
With System Switch in COOL, Fan Switch in LOW AUTO
and room temperature ABOVE setpoint temperature, you
should have continuity between red wire (Pin 2) to black
wire (Pin 4) and yellow wire (Pin 5). You should NOT have
continuity between red wire to violet, white or blue wires.
With room temperature BELOW setpoint temperatures, you

should NOT have continuity between red wire to violet,
white, black, yellow or blue wires.
With system switch in COOL, 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) and yellow wire (Pin 5). You should NOT have continuity
between red wire to violet, white or blue wires. With room
temperature BELOW 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 System Switch in COOL, 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), yellow wire (Pin 5) and blue wire (Pin 6). You should
NOT have continuity between red wire to violet or white
wires. With room temperature BELOW setpoint tempera-
ture, 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 OFF, Fan Switch in HI AUTO or
LOW AUTO and room temperature ABOVE or BELOW
setpoint temperature, you should NOT have continuity be-
tween red wire to violet, white, black, yellow or blue wires.
