Minimum cut-in voltage / uLi
Sub function: Up
Minimum cut-out voltage / uLo
Maximum voltage / uHi

setting uHi, followed by uLo and uLi .
uLi: When the compressor is due to start, the voltage of the power supply will be

given in this parameter .
uLo: When the compressor is running, it will be switched off if the voltage goes

below that given in this parameter .
uHi: When the compressor is running, it will be switched off if the voltage exceeds

Power On Delay / Pod
1 Click: Temperature setpoint
Sub function: Up
This is the delay in seconds between power-on and the compressor being
activated . Depends on the Power on Temperature setting as explained below .
Power Factor / PFA
This value is hidden by default . The parameter is used by the Zero Cross function
to optimize the switching position of the relay contact .

Sub function: Down
Sub function: Up
if the control temperature is between cut-in and cut-out at power up customers can
determine if the compressor shall start immediatly (yes) or wait for cut-in tempera-
ture to start (no) .
Power on Temperature / PoT
This parameter is used to accelerate the first application test on the OEM assembly
line; if the cabinet temperature is higher than this parameter the Power On Delay is

overruled and the outputs are activated without delay .
Compressor Door Open Delay / Cdd
This parameter sets the delay in minutes before the compressor stops when the
door is opened . If set to zero, the function is disabled .
