Control Logic
Unit Power ON/OFF
The unit is turned ON when:
-
One of the fan speed inputs (H/M/L) is ON
-
ON/OFF signal input is ON.
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.
Alarm Protection and Error Display
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.
If the float switch is open for 10 minutes, the LED display reports a condensate management failure (see
table on the next page).
Drain-Pump Run Management
When the unit turns ON:
-
If Ti1
-
If Ti1 ≥ 15 ºC, the drain pump turns OFF.
When the unit turns OFF and the drain pump is ON: the drain pump will remain ON for 5 minutes, before the drain
pump turns OFF.
At any time:
-
If the float switch is OPEN, the drain pump will turn ON.
-
If the float switch is OPEN and then CLOSES, the drain pump will remain ON for 5 minutes, and then
turn OFF.
Swing and Louver Control
When the unit is OFF, the louvers are closed (angle at 100º against vertical).
When the unit turns ON, the louvers open (angle at 87º against the horizontal).
When the unit turns OFF, the louvers returns to a closed position (100º against the vertical).
Modulating Signal Input
When the “Auto ON/OFF” 230VAC input is ON, the fan motor rpm speed shall be modulated by the “+/-”
low voltage modulating signal input.
The standard configuration is for 0~10VDC modulating signal input.
The optional configuration is for 0~5VDC modulating signal. To set the PCB to the optional configuration,
the S1 jumper must be closed.
