HEAT METERING PARAMETERS

Group W contains parameters to set the solar heat metering.
The procedure for setting function parameters is the same as for service
parameters (see page 30).
Parameter description
Setting of runnig period for boiler circulation pump if a boiler
temperature rise of 2 °C is detected. Circulation pump is
running until there is a temperature difference between boiler
and boiler return pipe.
considered at delayed switchovers with valves.
This setting defines how boiler circulation pump shall operate:
1- STANDARD means that circulation pump is running accor-
ding to setted minimum boiler temperature and according to
temperature difference between return pipe and boiler tempe-
rature.
2- ALWAYS means that circulation pump is running always
when boiler temperature is higher as setted minimum boiler
temperature. Such operation mode is used for systems of
pellet boiler without sensor in storage tank.
Setting of mixing valve position correction intensity. Smaller
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 chan-
ges. Smaller value means low sensitivity, higher value means
high sensitivity.
Setting of mixing valve running time to compensate the bac-
klash of actuator and mixing valve assembly, which occours
by change of rotation direction.
