Example:
Once the pre-set flat temperature has been reached (signalised by the room regulator), the pre-set CH boiler
temperature will be reduced to 45°C, which is only by 10°C although the Room reg. temp. lower parameter is set
to 15°C.
6.1.1.5.3 Change of pre-set temperature
NOTE
This parameter concerns the RS proportional regulator function.
This setting determines by how many degrees the valve temperature is to increase or decrease with a single unit change in room
temperature (see: Room temperature difference) This function is active only with TECH room regulator and it is closely related to
the Room temperature difference parameter
Example:
Case 1:
If the room temperature rises to 23,5ºC ( 0,5ºC above the pre-set room temperature), the valve closes until 39ºC is reached ( 1ºC
change).
Case 2:
If the room temperature drops to 22ºC (1ºC below the pre-set room temperature), the valve opens until 42ºC is reached (2ºC
change - because every 0,5°C of room temperature difference, the pre-set valve temperature changes by 1°C ).
6.1.1.5.4 Room temperature difference
NOTE
This parameter concerns the TECH proportional regulator function.
This setting defines the single unit change in the current room temperature (with the accuracy of 0.1°C) at which a predefined
change in the pre-set temperature of the valve will be introduced.
