>> 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 feature 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.

>> Operating Tips
:: HUMIDIFICATION FAN should be set to ON when running steam or mist humidifiers.
:: HUMIDIFICATION FAN should be set to OFF when running drum humidifiers or
any other humidifier that requires the furnace to run in order to make humidity.
:: DE-HUMIDIFICATION FAN (DH) should be set to on when running separate de-
humidification equipment.
:: DE-HUMIDIFICATION FAN (DH) may be set to off when using the air conditioning
as a means of de-humidification. It may advantageous in some environments to
turn the fan on independently when there is a call for DH in order to distribute the
humidity level more evenly.
:: DH REVERSE function can be configured to meet the requirements of many vari-
able speed fans, consult the manual of your variable speed fan and determine
if an “open” or “closed” contact results in slowing fan operation.
