Basic Setup & Configuration
Control Board Configuration
Temperature Set Point – Located on the back of the control board is a dial labeled “SET POINT”. This
dial is used to set the desired output temperature.
Setting the desired output temperature is completed in three 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 (10°C).
 Step 2 – On the backside of the control module (hinged door) is a jumper labeled “TEMP
RANGE” (J21). This jumper allows for two temperature range options: HI or LO. Place
the jumper to select the correct range based on the determined set point (step 1).
 Step 3 – using a small screwdriver, adjust the SET POINT dial according to the desired
operating temperature.
