CHECKOUT
NOTE: The furnace blower must be on for the humidifier to
operate (does not apply to steam humidifier
applications).
MPORTANT
When an outdoor sensor is not installed, allow
12 to 24 hours for the humidifier to start operating.
This delay is caused by the method used to
determine outdoor temperature conditions. If the
furnace is off for more than 24 hours or the outdoor
temperature sensor reads greater than 63
°
F, the
control enters an auto off mode where it does not
allow humidification until the furnace cycles or the
outdoor temperature drops below 60
°
F. This is to
prevent the humidifier and air conditioner from
running simultaneously. The control may enter
dehumidification mode if the house dewpoint rises
above 58
°
F.
Outdoor Temperature Sensor Checkout
Check the thermistor sensor by comparing its resistance to
the temperature as measured by an accurate thermometer.
The resistance of the thermistor sensor inceases as its
temperature values drops. Table 4 shows approximate sensor
resistance values at various temperatures.
Test Mode
Use the following procedure to place the control in the test
mode and call for humidification:
1. Turn the frost factor setpoint dial to the Test position.
2. Do one of the following:
a. At the thermostat, with the System switch set to
Heat and the Fan switch set to Auto, move the
temperature setpoint about 10°F (6°C) above the
room temperature to call for heat, or
b. Set the System switch to Off and the Fan switch
to On for continuous fan operation.
3. Verify humidifier and/or dehumidifier/ventilation unit is
activated.
In the test mode, the indicator light remains on continuously
with a call for heat or fan; otherwise, it remains lit for four
seconds and turns off for one second. This flashing sequence
continues until the control is taken out of the test mode. After
thirty minutes, the control automatically resets to the
maximum frost factor setting. If system checkout is not
completed within thirty minutes, the test mode can be
extended by turning the dial back to one of the dial settings
and then returning it to the test mode. After the system has
checked out, return the control to the desired frost factor
setting. See the Adjustment section.
