Data display
During complete operating period the display shows temperature of VF mixed flow.
When T1 (
∆
AS) key is pressed
the display shows the difference between actual temperature of mixed flow (T
actual
) and temperature of mixed flow acc. to preset
curve (T
per curve
) in °C.
∆
AS= (T
actual
) - (T
per curve
)
When value “
∆
AS" is negative it indicates that the temperature in the room is too high and controller decreases the temperature of
heating water line. When value "
∆
AS" is positive it indicates that the temperature in the room is too low and controller increases the
temperature of heating water line. The parameter E, selected from displayed value AS, can be used for calculation of the difference
(
∆
T
room
) between actual room temperature and required room temperature.
When T2 (BF/KF) key is pressed
the display shows floor temperature or temperature in the boiler.
When T3 (AF) key is pressed
the display shows outside temperature.
