NOTE: To enter the Energy Savings mode, press the
ON/OFF/ENERGY SAVINGS button until the words Energy
Savings appear on the left side of the display. Energy Savings
mode enables the settings that were selected in the Configuring
the Controller section earlier in this manual.
Sampling Mode
When the ventilator is in Energy Savings Mode and either of
the incoming air temperature or humidity is outside the limits
programmed in the controller, the unit will enter "Sampling Mode".
In Sampling Mode, the fan will shut down for 15 minutes followed by
a 5-minute run period. The ventilator will continue this 15 minutes
off/5 minutes on cycle until the intake air conditions are within the
temperature and humidity limits programmed into the controller.
The controller will also enter Sampling Mode if the intake air drops
below 33°F (1°C). It will cycle 5 minutes on / 15 minutes off until
the temperature rises about 34˚F (2˚C).
IO-DPV
2. When the ventilator is on, the screen will display the current
temperature and relative humidity of the incoming outdoor
intake air as well as the ventilator's operating mode (Energy
Savings mode or not). Additional icons and information that may
be displayed on the screen include:
− Ventilator icon appears when the ventilator is on.
− HI° F appears if the intake temperature is above 150° F (66° C)
− Lo° F appears if the intake temperature is below 15° F (9° C)
− Lo% appears if the intake humidity is below 10%.
Optional Heater Accessory Unit
An optional heater unit, model DQ-P-70-AH-H, is designed for climates
where the outdoor air entering the ventilator can fall below 54° F (12°C).
To install the heater unit, follow the instructions provided
with that unit. Once installed and power is supplied to the
heater unit, the ventilator controller LCD screen will now also
display a thermometer icon. When the temperature of the
intake air is between 39°F and 54° F (4 and 12° C), the heater
unit will operate on Stage 1 heating and the number 1 will be
displayed on the ventilator LCD screen; when the temperature
is between 33° F and 39°F (1 and 4° C), the heater unit will
operate on Stage 2 heating and the numbers 1 2 will be
displayed on the screen.
Optional Motorized Damper
An optional Motorized Damper Kit, model DQ-P-MDV (sold
separately) can be installed with the ventilator. When attached and
wired to the ventilator, the Motorized Damper will open when the
ventilator is operating and will close when the ventilator is turned
off. For installation specifics, refer to the instructions included with
the DQ-P-MDV Motorized Damper Kit.
Factory Reset
To restore the ventilator controller to factory default settings,
make sure the unit is in the OFF setting. Push and hold both the
UP and DOWN buttons for approximately 5 seconds until the word
OFF on the display flashes once to confirm that the settings have
been restored.
Maintenance
CAUTION!
Make sure power is switched off at the electrical service panel
i
before servicing the unit.
1. Cleaning the Fan Assembly: Wipe all parts with a dry cloth
or gently vacuum the fan. NEVER IMMERSE ELECTRICAL
PARTS IN WATER.
2. Inline Air Filter: The air filter in this ventilator should be
checked every month and replaced at least once every
3 months or more frequently if the airflow restriction
becomes too great. To remove the spent filter, reverse
the instructions outlined in the Installing or Changing the
Air Filter section earlier in this manual.
NOTE: If you notice a large amount of insects and debris in
the air filter, this could be a sign that the Air Intake Hood
might be compromised and need repair or replacing.
