E.5. Control Logic Specification
E.5.1. Unit Power ON/OFF
i. The unit is turned ON when any of the fan speed inputs (H/M/L) are ON, OR Auto ON/OFF signal
input is ON.
ii. The unit is turned OFF only if all of the fan speed inputs (H/M/L) are OFF AND Auto ON/OFF signal
input is OFF.
E.5.2. Alarm Protection and Error Display
i. If the float switch is open for 5 minutes, then the (NC) voltage ‐ free alarm contact shall be open
and the (NO) voltage free alarm contact shall be closed.
ii. If the float switch is open for 10 minutes, the LED display reports a condensate management
failure (see table on the next page).
E.5.3. Drain ‐ Pump Run Management
i. When the unit turns ON:
a. If Ti1 < 15 ºC, the drain pump turns ON.
b. If Ti1 ≥ 15 ºC, the drain pump turns OFF.
ii. When the unit turns OFF and the drain pump is ON:
The drain pump will remain ON for 5 minutes and then turn OFF.
iii. At any time:
a. If the float switch is OPEN, the drain pump will turn ON.
b. If the float switch is OPEN and then CLOSES, the drain pump will remain ON for 5
minutes, and then turn OFF.
E.5.4. Swing and Louver Control
i. When the unit is OFF, the louvers are closed (angle at 100º against vertical).
ii. When the unit turns ON, the louvers open (angle at 87º against the horizontal).
iii. When the unit turns OFF, the louvers return to a closed position (100º against the vertical).
E.5.5. Modulating Signal Input
i. When the “Auto ON/OFF” 230VAC input is ON, the fan motor rpm speed shall be modulated by the
“+/ ‐ ” low voltage modulating signal input.
ii. The standard configuration is for 0~5VDC modulating signal input.
iii. The optional configuration is for 0~10VDC modulating signal. To set the PCB to the optional
configuration, the S1 jumper must be closed.
