Parameter description
Setting of minimal allowed setpoint temperature in heating
mode. Setpoint temperature cannot be adjusted lower as
with this parameter.
Setting of maximal allowed setpoint temperature in heating
mode. Setpoint temperature cannot be adjusted higher as
with this parameter.
Setting of minimal allowed setpoint temperature in cooling
mode. Setpoint temperature cannot be adjusted lower as
with this parameter.
Setting of maximal allowed setpoint temperature in cooling
mode. Setpoint temperature cannot be adjusted higher as
with this parameter.
Setting of mixing valve running time to compensate the
backlash of actuator and mixing valve assembly, which
occours by change of rotation direction.
Setting of mixing valve position correction intensity. Smal-
ler value means shorter movements, higher value means
longer movements,
Setting of mixing valve control frequency - how often
mixing valve position is being controlled. Smaller value
means low frequency, higher value means higher
frequency.
Sensitivity of mixing valve for stand-pipe temperature
changes. Smaller value means low sensitivity, higher
value means high sensitivity.
Setting of initial valve movement duration when moving
from open position. With this setting the valve is moved
to its control range and immediate controller respond at
startup of system.
Setting of initial valve movement duration when moving
from closed position. With this setting the valve is moved
to its control range and immediate controller respond at
startup of system.
