By installing an external sensor
It is used to measure outdoor temperature. The sensor is installed on the north-facing facade of the house, approximately 1.2m above the floor, not above the windows or vents and, if possible, on an insulated wall or facade.
The sensor is also supplied with mounting fittings. You should pay particular attention to the spacer with which the sensor is mounted so that it is at a distance from the surface of the external wall. This provides a more accurate measurement of the actual external temperature with the interference by the passage of heat through the external walls of the house.iše.
When the wall is not insulated and interior spaces are heated, it is recommended to use an additional insulation lining to distance the sensor from the wall. You can use a piece of wood or a piece of styrodur panel.
In addition, the Seltron controllers also allow the calibration or correction of the display of individual temperatures. The correction is carried out using the parameters S1.13 to S1.20. I recommend that the correction for the external sensor is carried out for a temperature of around 0°C. The AF sensors can also be used to measure room temperature in industrial or other facilities where it is required that the sensor is more robust and resistant to mechanical damage.
