 Hysteresis - This function is used to set the hysteresis of pump activation temperature.
 Sensor – This function is used to select the sensor which will provide temperature readings for additional heat
source activation/deactivation.
 Room regulator – This function is used to select the room regulator which will influence additional heat source
operation. When the pre-set temperature of this regulator is not reached, the controller will enable the
additional heat source regardless of current temperature of the selected sensor.
Example:
Part of the heating system is handled by fireplace and gas boiler. CH boiler is connected to voltage-free contact and the
fireplace temperature is read from sensor T4 (CH). The pump will be enabled when the sensor temperature does not
exceed <activation threshold>. The pump will be disabled when the room temperature is reached or when T4 sensor
exceeds <activation threshold>.
