Function details
1. Heating control:
Heater starts heating when cold-room temperature< (set temp.- hysteresis) and stops heating when
cold-room temperature >set temperature.
2. Abnormal work mode
When cold-room is short-circuited, HH is displayed; when the cold-room sensor is
open-circuited, LL is displayed. At the same time alarm LED flashes.

 

Notes for Installation:
1. The sensor cable leads must be kept separately from main voltage wires in order to avoid high frequency
noise induced. Separate the power supply of the loads from the power supply of the controller.
2.
The temperature controller can not be installed in the area with water drops.
In case of long-distance sensor installation from the controller, the sensor cable may be prolonged up to 100 m max. without any re-calibration.
3.

The temperature controller can not be installed in the area with water drops.
