3.12 Pump down
The pump down function can be activated when the parameter H1 = 5 and c7 ≥ 7.
The AUX relay is then dedicated to the pump down valve.
Digital input DI1 has to be congured as a low pressure switch A4 = 8 or pump down will be performed by
time if c10 = 1.
To start with pump down, control of the Fullmotion compressor needs to stop, then pump down starts. An
immediate pump down can be performed by setting cct = 0.
If c10 = 1 and no pressure switch is congured (A4 = 8) the pump down lasts for the time c7.
The compressor start can be delayed by the time c8.

3.13 OFF from keypad
Pressing the ON/OFF button for more than 3 seconds switches the controller ON/OFF.
If speed control is running, the Fullmotion compressor is forced to run at the minimum speed set by cmf for
a xed time of 30 sec.
If the controller is congured for pump down, the controller activates pump down management.
