Light control
Relay AUX 1 or AUX 2 must be configured as “Light” (o00, o10 or o20=2).
Switching the lights on or off is controlled using:
• The LIGHT
push-button
: One press switches the lights on or off.
•
The cold room door:
When the door is opened, the lights remain on for the time defined by parameter b01.
If the value is 0, when the door closes the lights go out. (One of the digital inputs must be configured as door
contact (l10 or l20=1). The control even occurs with the equipment in Stand-by.
Password
Allows the configuration of the equipment to be protected by a 2-digit code.
If it is active a code is requested when you try to access the programming menu. This menu
cannot be accessed if a wrong value is entered. The code is set via the PAS parameter.
Parameter b10 defines the operation of this code.
Remote Stand-by mode
This allows activating Stand-by mode using a switch connected to one of the digital inputs.
Said digital input must be set to Stand-by remote activation (I10=8 or I20=8).
Operation of the auxiliary relays
Depending on the controller model, it may have 1 or 2 auxiliary relays. The function of these relays is configurable
via the parameter menu.
AUX 1 relay
• Deactivated (o00=0): Does not carry out any function.
• Compressors / crankcase resistor (o00=1): Controls compressor operation. When the compressor is not in
operation, it powers the crankcase resistor. This function can only be selected via the initial wizard (
In{
).
• Light (o00=2): This regulates the operation of cold room light (See page 31).
• Virtual control (o00=3): The relay can be remotely activated and deactivated by means of AKONet software.
• Alarm (o00=4): This activates the relay every time that an alarm occurs (See page 28).
• Door frame resistor (o00=5): This controls the operation of the cold room’s door frame resistor (See page 22)
• Drainage resistor (o00=6): Controls the activation/deactivation of the evaporator drainage resistor (See page 27).
AUX 2 relay
• Deactivated (o10=0): Does not carry out any function.
• Alarm (o10=1): This activates the relay every time that an alarm occurs (See page 28).
• Light (o10=2): This regulates the operation of cold room light (See page 31).
• Virtual control (o10=3): The relay can be remotely activated and deactivated by means of AKONet software.
• Defrost 2
nd
Evaporator (o10=4): This controls the defrost resistors of a second evaporator (See page 26).
• Door frame resistor (o10=5): This controls the operation of the cold room’s door frame resistor (See page 22)
.
• Same as solenoid status (o10=6): Imitates solenoid status: active if the solenoid is in ON mode, inactive if the
solenoid is in OFF mode.
• Same as unit status (o10=7): Indicates the unit’s status: active if the unit is in ON mode, inactive if the unit is
in Stand-by mode.
• Drainage resistor (o10=8): Controls the activation/deactivation of the evaporator drainage resistor (See page 27).
