5. External sensor connection - option
The external sensor must be Meitav-tec type.
Before making any changes disconnect power to the main board.
Table 5.1 - N.TC. Sensor: Temperature ~ Resistance Characteristics
Temp °C 7.2 10.0 12.8 15.6 18.3 21.1 23.9 26.7 29.4 32.2
Res. k 115.8 100.9 88.1 77.1 67.7 59.6 52.5 46.4 41.2 36.6
The default from factory is INTERNAL SENSOR.
To switch to temperature readings from an EXTERNAL SENSOR:
1. Disconnect power to the thermostat.
2. Move DIP switches 1,5 and 6 as shown in the picture below
Switch 1 - OFF
Switch 5 - ON
Switch 6 – OFF
3. Connect the temperature sensor to T-T terminals.
4. Reconnect power to the thermostat.
The wire length for the sensor can be up to 30 meters (100 feet) with standard cable.
If the distance is greater than 30 meters (100 feet) then it MUST be shielded.
