ADVANCED SETTINGS - HUMIDITY SETTINGS

De-humidification options for increasing comfort and efficiency
• HRV/ERV units can be controlled by simply connecting the DH terminal on the thermostat to the
terminal DH of the HRV/ERV. Most HRV/ERV units will control properly with the DH REVERSE fea-
ture turned off (contact normally open).
• OPTION 1: In Advanced Settings choose DHControlComp, set to ON then lower the temperature
to a minimum safe set point, finally set the desired de-humidity level, de- humidify will control
the compressor (unless minimum temperature set point is reached) whichever comes first.
• OPTION 2: Connect terminal DH to Y1 and set thermostat to de-humidify mode then regardless
of temperature the de-humidification setting will have priority. Caution: This method will run the
compressor until the de-humidification level is reached and may cause overcooling.
• OPTION 3: Connect the DH terminal to a variable speed fan control, (set DH REVERSE to control
the fan so that low speed is activated to de-humidify). This method provides maximum comfort
while maintaining the temperature in cooling mode.
