See Fig. 118.
NOTE:
Heat includes Heat, Emergency Heat and
Auto. If the system is in Auto mode, the ther-
mostat will allow humidification if the last
call was for heat.
Cool includes Cool and Auto. If the system is
in Auto mode, the thermostat will allow
humidification if the last call was for cool. A
discharge sensor is required to humidify in
the Cool mode. The thermostat prevents
condensation in the duct work by not allow-
ing the humidifier to run when the discharge
temperature goes below the dew point tem-
perature. The humidifier is allowed to run
again after the discharge temperature rises
above the dew point temperature.
