FAN SPEED
—The operator can select between AUTO or MANUAL fan speed
control. Pressing the FAN SPEED button will switch speed from AUTO to MANUAL.
In MANUAL mode, pressing the FAN SPEED button will change fan speed from low
to high. In AUTO mode, the fan speed is controlled automatically. In cooling mode,
the controller automatically adjusts the fan speed to high, and as the inside tempera-
ture approaches the set point, the fan speed will reduce. In heat mode, the fan speed
adjusts from low to high as the temperature reaches the set point

P4—Temperature Sensor Calibration, +/- 10°
P10— Temperature Display, °F or °C
P13—Supply Fan Operation, Cycling or Continuous
P1, P2 - To adjust fan speed settings, P1 represents the high fan speed parameter, while
P2 represents the low fan speed parameter. When using nozzle kits, discharge duct
adapters and evaporator plenums, setting P1 to 85 will help to avoid freeze ups.
P4 - Adjust the P4 setting to match the actual INSIDE room temperature, if needed.
P10 - Use this parameter to display temperatures in the desired units.
P13 - To cycle the evaporator fan with the compressor, access code P-13. Press the up or
down button to switch to "CYC", which means cycle the fan with the compressor. The
factory default setting is "CON", which means continuous fan operation.
