• Weather control – preset temperature of water circulating in the heating circuit reference is with regard to

Heating circuit control depending on external temperature (weather).
The parameters available when choosing a the Control method = Weather control. • Heating curve – choice in
the form of a graph of the heating curve, in range of 10..42ºC, appropriate for the type of building. The higher
heating curve the higher the temperature of the water in the heating circuit. • Curve parallel move – parameter
When Control method = Continous control then the heat source is turned off when you reach the Preset
temperature. When the temperature falls to the heat source is turned on again. This parameter is not available
When the Control method = Continous control, decrease the preset temperature water in circulation during the
Economic mode and Auto mode and during operation time schedule. In other modes temperature water circuit
This parameter can be used only when Room thermostat = ON. Exceeding a preset room temperature causes
decreasing preset temperature of water in the heating circuit by Decrease of thermostat value. Decreasing
the preset temperature takes place upon contact trips the thermostat. Preset temperature of water inside the
heating circuit is not changed if Decrease of thermostat = 0. Parameter disappears when Room thermostat =
