limits:
i. TIMED: no temperature limits
ii. AUTO – B: Ventilation is not allowed if the ODT > 100°F or
ODT < 0°F; ventilation is allowed only when the heat is
on if the ODT is between 0°F and 20°F
iii. AUTO – C: Ventilation is not allowed if the ODT > 100°F or
ODT < 0°F
iv. AUTO – D: Ventilation is not allowed if the ODT > 90°F;
ventilation is allowed only when the heat is on if the
ODT is between 0°F and 40°F
e. Press the Mode button and then use the
to set the ventilation time (minutes/hour)
f. Press the Mode button repeatedly until the word DONE
appears on the display
Whenever the heating, cooling or dehumidifier is active, the

The dehumidifier can be configured to condition two
independent spaces Zoning requires the installation of
ductwork and dampers to direct air to and from two locations
NOTE: Dehumidifier zoning is not recommended in HVAC zoning
applications
In this installation the dehumidifier controls the humidity
in two separate zones, a Primary and Secondary Zone The
dehumidifier will dehumidify the Primary Zone as the first
priority and will switch to the Secondary Zone after the
dehumidification needs of the Primary Zone have been
satisfied.
IMPORTANT: Normally Closed dampers must be installed in the
ducts serving the Primary Zone and Normally Open dampers
installed in the ducts serving the Secondary Zone
