Basic Setup
Temperature Set Point –
Located on the control board is a dial labeled SW1. This dial is used to set the
desired output temperature.
Setting the desired output temperature is completed in two steps. See
Figure 1
for temperature ranges.
Step 1
– Determine the required temperature output for the application.
o
HINT:
Most Make-Up Air applications suggest an output set point typically
around 50°F.
Step 2
–
using a small screwdriver, adjust the WARM AIR dial according to the desired
operating temperature.
Step 3 –
Verify mode is set to #7.

Factory default, position 6 (50° F)
NOTE: MODE dial must = #7
Fan Speed Adjustment –
located in the hinged cover low voltage compartment and on the divider is a
plastic shaft knob which allows for fine tuning the fan speed. If you do not need full CFM for your
application and desire a larger temperature rise, the lower factory default set speed may be adequate.
However, you must realize the CFM must maintain the appropriate requirement for balancing the building
inlet to the outlet mechanical driven air.
NOTE:
Factory default setting is low, full clockwise. To increase speed turn dial counter-
clockwise.
COMMENT:
The fan low speed is approximately 120 CFM.
