Page 26: Selecting The Temperature Sensor (Dif)
10.1. Selecting switching sensitivity (DIF) It is possible to set the switching sensitivity. By setting this val ue, you can specify how much the appliance switches the outputs on/off below/above the set temperature. The lower this value, the more consistent the internal room temperature, the greater the comfort is. -
Page 27: Antifreezing (Fre)
10.3. Antifreezing (FRE) When the antifreezing function of the thermostat is activated, the thermostat will switch on its output, regardless of any other setting, when the temperature measured by the thermostat goes below ±3 °C. When the temperature reaches 7 °C, normal operation of the output is restored (according to the set temperature). -
Page 28: Switching Between Heating, Cooling And Ventilation Modes (Fun)
10.5. Changing between heating, cooling and ventilation mode (FUN) You can easily switch between heating (00; factory default), cooling (01) and ventilation (02) modes. The connection points of the thermostat output relays close at a temperature below the set temperature in heating mode and at a temperature above the set temperature in cooling mode (taking into account the set switching sensitivity). -
