Hysteresis / minimum on-time
◆This function prevents an unnecessary large number of
switching operations by setting a minimum on-time
◆This prevents the DuoFern Room Thermostat 9485 tripping
too often if the room temperatures fluctuate
Offset (sensor offset)
◆The temperature measured on site can vary slightly from
the room temperature if the DuoFern Room Thermostat
9485 is installed in a unfavourable position (e.g. behind a
curtain or on a cool exterior wall)
◆An adjustment of the measurement in the range of - 5.0°C
to + 5.0 °C can be carried out using the sensor offset
