Heating curve - this is the curve according to which the set temperature of the controller is determined
on the basis of the external temperature. In order for the valve to operate properly, the set temperature
(downstream the valve) is set for four intermediate external temperatures: -20°C, -10°C, 0°C and 10°C.
There is a separate heating curve for the
temperatures of: 10°C, 20°C, 30°C, 40°C.

Controller type
→ Control without room regulator - This option should be selected if the room regulator is to affect the operation
of the valve.
→ RS regulator decrease – This option is checked if the valve is to be controlled by a room regulator equipped
with RS communication. When this function is chosen, the controller will operate according to the
temp. lower parameter.
→ RS regulator proportional - When this controller is chosen, the current boiler and valve temperatures can be
viewed. With this function checked, the controller will operate according to the
