Humidistat-Thermostat
OPERATION
TEMPERATURE CONTROL
4. Use the equilibrium moisture chart be
low as a guide for setting the humidistat.
3. Set the humidistat to the desired relative hu-
midity level you want to maintain under
your drying floor. The heater will cycle on
above this relative humidity, and off when
this level is reached.
1. Set bypass switch to the "HUMIDISTAT ON"
position. This setting allows the unit to run based
on temperature and humidity.
2. Set the thermostat (Humidistat-Thermostat units
only) to the maximum temperature desired. This
allows the thermostat to funciton as a highlimit
control only. See the above temperature control
for setting the thermostat.
5. Monitor the thermometer on the thermostat
housing. When the thermometer comes up
1. Turn the fan unit on and let it run 3 to 5 minutes to
equalize temperature under the bin.
2. Set bypass switch to the "HUMIDISTAT OFF"
position. This setting allows the unit to run based
on temperature only.
3. Rotate the thermostat knob clockwise to the
warmest position.
4. Open the gas valves to the heater, and turn the
heater on . Set heater gas pressure to a moder-
ately high setting (5 to 10 PSI).
7. Watch the unit run through several cycles and
make any final adjustments. (Note: The unit should
be on approximately 80% of the time. If not
adjust gas pressure).
8. Significant changes in outside air temperature
may require readjustment of gas pressure.

to the desired temperature, slowly turn the ther-
mostat knob counter-clock-wise until the
heater cycles off.
6. If the unit does not reach the desired temperature,
gradually increase the gas pressure until the tem
perature rises to the desired level.
