Hot-gas defrosting
Set parameter d1 =1 to defrost in cycle inversion
mode.
The compressor relay and defrost relay are activated
throughout the defrost phase.
To ensure proper control of the system the installer
must use the defrost output: this must allow
opening of the cycle inversion solenoid valve and
closure of the liquid solenoid valve.
For capillary systems (without thermostat valve) the
cycle inversion solenoid valve can be controlled via
the defrost relay control.
Pump-down function
Pump-down function is activated when parameter
AU=4 (for version with AUX/Alarm relay only).
Connect pump-down pressostat on the digital input
INP-1.
The compressor is directly controlled by pressostat.
Connect evaporator solenoid valve on the AUX
relay. The solenoid is controlled directly by the
thermostat.
Password function
The protection function is activated when
parameter PA is set to a value other than 0.
See parameter P1 for the dierent protection types.
When PA is set, protection starts after two
minutes of inactivity. 000 appears on the display.
Use the up/down keys to change the number, and
the set key to conrm it. If you have forgotten your
password, use the universal number 100.
