Difference sensor
Using two sensors a differential thermostat can be created. When the difference in temperature between both sensors
reaches a certain value, a relay channel can be activated.
To achieve this, the one sensor must know the address of the other one (see paragraph on differential thermostat).
1. Push the ‘Location’ button until the first sensor of the
differential thermostat is displayed.
2. Press and hold the ‘Menu’ button for ±4 seconds to
open the extended menu.
3. Scroll through the extended menu using the ↑ or ↓
button until the ‘Sensor settings’ item appears.
4. Select the sensor settings menu with the → button.
5. Scroll through the sensor settings menu using the ↑
or ↓ button until the ‘Diff. Sensor‘ item appears.
6. Select the diff. sensor item with the → button.
7. Select the second sensor of the differential
thermostat using the ↑ or ↓ button.
Remark:
If no differential thermostat is needed, the entry field
must remain empty (‘---‘).
8. Confirm with the → button.
9. Exit the menu with the 5 button.
