Other parameters
Using parameter d5, you can configure whether the unit performs a defrost (d5=1) or not (d5=0) when it receives
power (first start-up or after a power supply failure). Should the option YES (d5=1) be selected, defrost will begin
once the delay time defined in d6 has elapsed.
Using parameter d8, we define the time tally established in d0, choosing between total time elapsed (d8=0) or the
sum of compressor operation time (d8=1).
REMARK: If parameter d1 is configured to 0, no defrosts are performed.
Management of the drainage resistor
Activates the drainage resistor before the start of defrost and deactivates it one hour
after finishing, avoiding unnecessary energy consumption in the absence of defrosts.
For this function to be active, parameter o10 (Relay AUX 2) should be set to 8.
Evaporator fans
Control of fans in standard mode (CE=0)
Fans are controlled through sensor 2 (evaporator) and parameters F0 (stop temperature) and F1 (sensor differential).
If sensor S2 is not connected or an error in the sensor (E2) is detected, the fans continuously operate without taking
into account parameters F0 and F1, but taking the remaining parameters (F2 to F4) into account.
Using parameter F2, the status of the fans during compressor stops is defined.
Using parameter F3, the status of the fans during defrost is defined.
Parameter F4 defines the fan start-up delay time after defrost (See page 23).
Parameter C22 defines whether fans stop when the door is opened.
Control of fans in SELFDRIVE mode (CE=1)
With the SELFDRIVE mode active, fan control is performed taking into account the evaporator temperature, compres-
sor, frost level, the cold room temperature and if the door is open or not, optimising its operation.
In this way its operation is optimised to obtain the greatest energy efficiency of the cold room.
With this mode active, only parameters F0, F1 and F4 need to be configured.
It is advisable to configure all parameters relating to the fans since, in the event of a calibration or oper-
ating error of the SELFDRIVE mode, the controller then temporarily regulates in standard mode.
