Computherm E400RF - Selecting the Switching Sensitivity (DIF); Calibration of the Temperature Sensor (ADJ)

11.1. Selecting the switching sensitivity (DIF)
It is possible to set the switching sensitivity. By setting this value, you can
specify how much the appliance switches the connected device on/o󰀨 below/
above the set temperature.
The lower this value, the more uniform the internal temperature of the room,
the greater the comfort will be. The switching sensitivity does not a󰀨ect the
heat loss of the room (building).
In case of higher comfort requirements, the switching sensitivity should be
chosen so as to ensure the most constant internal temperature. However, also
make sure that the boiler is switched on several times hourly only at low out-
door temperatures (eg -10 °C), as frequent switching o󰀨 and on will impair the
e󰀩ciency of the boiler’s operation and increase gas consumption.
The switching sensitivity can be set between ±0.1 °C and ±1.0 °C (in 0.1 °C
increments). Except some special cases, we recommend setting ±0.1 °C or
± 0.2 °C (factory default setting). See Chapter 9 for more information on swit-
ching sensitivity.
11.2. Calibration of the temperature sensor (ADJ)
The measuring accuracy of the thermometer of the thermostat is ± 0.5 °C. The
temperature displayed by the thermostat can be modied in 0.1 °C increments
in comparison to the temperature measured by the temperature sensor, but the
modication can not exceed ± 5 °C.
