The linear characteristic curve is defined via two fixed points (voltage value 1 / function
value 1 and voltage value 2 / function value 2).
Room temperature 10V
The voltage signal present at input Hx is converted into a linearized room temperature
value. This, in conjunction with the indoor relative humidity, is used to calculate the
dewpoint temperature in the cooling circuit.
If there is no room unit with a room sensor (BSB) connected for heating/cooling circuit
1, the room temperature measured at Hx is also used for room heating/cooling 1
(variant with compensation and room influence).
The linear characteristic curve is defined via two fixed points (voltage value 1 / function
value 1 and voltage value 2 / function value 2).
NC
The contact is normally closed and must be opened to activate the selected function.
N/O
The contact is normally open and must be closed to activate the selected function.
The function "Min flow temp setpoint" on operating line 5950 or 6046 is activated via
contact H... The generating plant is controlled constantly at the temperature level set
here, either until contact H.. opens again or until a higher heating/cooling demand is
delivered.
