Door microswitch
To reduce frost on the evaporator, the door microswitch interrupts
the unit operation when the cold room door is open. It also controls
the cold room lamp. The door microswitch is an accessory.
Door heater
For low temperature applications it is suggested to install a door
heater. It prevents the door from freezing. The choice for the most
appropriate door heater is left to the installer or cold room
manufacturer. Sometimes the door heater is already included in the
pre-fabricated door kit.
INFORMATION
The door heater accessory is only necessary for low
temperature applications.
Cold room lamp
The lamp is ON when the cold room door is open. It is controlled by
the user interface. The cold room lamp is an accessory.
INFORMATION
As there are only 3 free cable glands, only 3 more options
can be installed.
Alarm
An alarm feature can be installed (light or sound).
Router
The unit (or multiple units) can be connected to the internet through
a router, available as an option.
Combining multiple units
To interconnect multiple units, a communication cable must be used.
