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
between RC to Y and RH to W. With room temperature
below setpoint temperature, continuity should exist be-
tween RC to G, RC to H and RH to W. No continuity would
exist between 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.
