Logic ID Description of application
IC1 Not Used
IC2 Condenser Pressure (PC)
T1 Evaporator Temperature (TE)
T2 Internal Temperature (TI)
T3 Air outlet Temperature (TM)
T4 External Air Temperature (TAE)
Not connected
IC3 Not used
In addition to the normal control functions, there are the following features:
Alarms
• Freecooling alarm: If (TI > 12) and ((TM – TI) > 2), ‘Warning’ is visualized. The reset is automatic
• Low pressure alarm: It becomes manual reset after 2 automatic reset
Control
If TI > 40 °C, the slave starts even without master authorization. This ends when TI < 37 °C.
In freecooling mode, if TI (master) > 22 °C, the slave support is request. This is no more requested when TI < 18 °C.
7.2. Custom 2
Standard control with different values of the setup parameters.
7.3. Custom 3
Standard control with different values of the setup parameters. Level alarm implemented (see alarm chapter and custom
4 paragraph).
7.4. Custom 4
Standard control with different values of the setup parameters. Level alarm implemented (see alarm chapter).
For custom 3 and 4, the signal of alarm is A3 DIG-IN, in substitution of signal for door open/intrusion.
The condensed water at evaporator fan is collected into a tank; when the level of the condensed water is too high, the
level alarm will be on. When the alarm is on, the compressor will be switch off.
The reset is automatic and it’s delayed of 20 seconds from when there isn’t the alarm condition.
7.5. Custom 5
The custom 5 has a dirty second filter alarm implemented, as the dirty filter but using the intrusion DIG-IN and the R12
relay. The alarm on A9 is ‘warning’ with automatic reset: EXTERNAL FAN ALARM.
The default value of parameters for Custom 5 are explained in the next paragraph.
