7.- Operation
7.1.- Compressor control
NORMAL OPERATION
If Pump Down is deactivated (P26=0), the compressor and the solenoid behave in the same way.
If Pump Down is activated (P26=1), the compressor and the solenoid behave as defined in section 7.5.
“CHANGE OF SET POINT” FUNCTION
It modifies the refrigerated facility's set point value.
It can be activated after a certain time has elapsed (defined in parameter
C11
) without activity in the cold room
door, to do this one of the digital inputs such as “door contact” (
P10 or P11 = 1
) must be configured.
Optionally, you can activate and deactivate this mode at will, using an external switch, configuring one of the
digital inputs as “Change set point” (
P10
or
P11
= 4).
If we set the
C11
parameter to 0, it can only be activated by external switch.

OFF
COMP.
ºC
When the temperature in probe 1 reaches the set
point value (
SP
) plus the differential of the probe
(
C1
), the compressor and solenoid are activated and
the temperature drops. When the set point value (
SP
)
is reached, the compressor and solenoid stop.

OFF
COMP.
ºC
Operation is the same as in the normal ode, but increasing the set point the
amount of degrees defined in the
C12
parameter.
