INTRODUCTION
The 105N4866 controller regulates temperatures in refrigeration appliances, including supermarket
refrigeration, freezer cabinet systems, and industrial kitchens.
The controller is a complete case controller with integrated inverter for variable speed compressors.
The controller is fully functional in every operation required for modern refrigeration control. The
controller connects to a range of interfaces such as potentiometers, LED displays, PC software, and bus
monitoring systems. The controller features an internal temperature and event logging system as well as
general-purpose interface for broad and flexible application.
The compressor should be operated under the following conditions:
>
Line voltage: Multi-Voltage (100–127V + 220–240V) operation 50/60 Hz
>
Ambient temperature: 0 to 43°C
The controller should not be used in ambient air containing acids or alkalies. To ensure an optimal service
life, the ambient temperature should be kept as low as possible (ambient temperature range for operation:
0 to 50°C compartment temperature, humidity 30–90%). The heat sink on the control units should not be
covered, and no objects should be lent up against the enclosure.
The control system should not be exposed to dust and water above the IP43 requirements.
Ambient temperature range for storage: -20°C to 70°C
The controller can be accessed via:
>
The local display CRA 162, 172, and 200
>
The Secop PC Service tool Tool4Cool
®
together with a RS485 gateway
>
A custom interface – please contact Secop for further information regarding custom interfaces.
