Parameter d1: time open in seconds for every 2 minutes of operation
• EXTERNAL - if there is an external drain (24VAC).
To change operation mode, use the parameter d3 (see par. 5.3 in List
of parameters).
Y
Only set the EXTERNAL mode in absence of the solenoid valve.
Otherwise the relative coil could become damaged.

List of parameters
A1 Sets the unit of measure for dew point in °C or °F.
A2/A3 Total hours of dryer operation= A3x1000+A2(display only).
Parameter d1 A4/A5 Like A2/A3 but for hours of refrigeration compressor opera-
tion.

A6 Sets Hd Warning intervention temperature (see par. 5.4 in
20
List of alarm/warnings).
A7 Inhibits remote OFF command.
b1 Sets the dryer address for serial communications.
b2 Sets the serial communication speed
b3 Not available
b5 Refrigerant evaporation temperature
b7 Not available
b8 Compressor discharge (delivery) temperature

C5
Dryer model: Mon = models
Note: if the C5 is set to = Mul in a monocooler dryer then
the warning ASE will occur. ASE is a warning for the mul-
ticooler models.
C7 Sets compressor operation mode:
- CYC = CYCLING (energy saving enabled)
- CON = CONTINUOUS (energy saving disable)
C36 Operating logic of the alarm/machine status relay.
0 = relay energised when dryer is running, de-energised if
in warning/alarm status.
1 = relay de-energised when dryer is running, energised if
in warning/alarm status.
2 = relay de-energised when dryer is running, energised
in warning/alarm status.
C37 % Energy saving
z d1 Sets the seconds of condensate drain opening (if set in
TIMED mode).
d2 Like d1, but for seconds closed.
d3 Sets condensate drain operation mode:
- CAP = INTEGRATED
- tIM = TIMED
- Con = EXTERNAL (24VAC)

5.4 Alarms and Warnings
Alarms cause the dryer to switch off .
Warnings only cause a signal.
In case of Alarm or Dew Point Sensor Warning (dSE), [
the alarm code. In case of a Warning,
fault code and the dew point and WARNING LED comes on.
If an alarm occurs:
1) Identify and eliminate the cause;
z
2)press to reset the alarm;
