- 22 or 24 AWG twisted shielded pair double insulated cable is recommended as sensor cable and its length must not exceed 25m.
- Do not bundle and run power cable and sensor cable in the same conduit.
- When using external sensor, run the cable away from any electric motor or power cable.
- Remove JP1 whenever using external sensor.
- Unoccupancy contact CLOSE activates unoccupancy mode.
- Unit to be opened by accredited servicing agents only.
- Electronic control - Type 2.B action (micro-disconnection operation).
- Separate collection for electrical and electronic equipment.

Error code
Error code will be displayed on LCD for following errors:
E-1 EEPROM read/write error
E-2 Temperature sensor open circuit
E-3 Temperature sensor short circuit
Remarks: If jumper JP1 is OPEN and external sensor is used, E-2 indicates external sensor may disconnected from terminals SR1 or GND.
Check external sensor connection and resistance value.
