Primary control/feed pump

Primary contr/system pump
The primary controller enables the flow temperature to be mixed up or
down for heatinggroups with flow temperature setpoints that are lower or
higher than the temperature present on the rail. The feed pump can
overcome the pressure drop to heatinggroups that are further away.
Flow temp setpoint min (2110) and Flow temp setpoint max
(2111)
With these boundaries a range for the flow setpoint can be defined.
Syst pump on heat gen lock (2121)
This parameter can set whether the system pump is also locked or not
when the generator lock is active.
Off: The system pump is not locked.
On: When the generator lock is active the system pump is also locked.
Mixing valve boost (2130)
For the admixture the boiler flow temperature actual value must be higher
than the requested setpoint of the mixer flow temperature, since this
cannot be corrected otherwise. The controller forms the boiler temperature
setpoint from the boost set here and the current flow temperature setpoint.
Actuator running time (2134)
Setting the actuator running time of the mixing valve used.
Primary contr/system pump (2150)
Before buffer: The primary controller/feed pump is arranged with existing
buffer storage tank hydraulically upstream of the buffer storage tank.
After buffer: The primary controller/feed pump is arranged with existing
buffer storage tank hydraulically downstream of the buffer storage tank.

Boiler

Release below outside temp (2203)
The boiler is only put into operation if the mixed outside temperature is
below the threshold set here. The switching difference is 0.5°C.
Full charging buffer (2208)
Under prog. no. 4810 (full charging buffer storage tank) is selected,
whether and when the buffer storage tank is fully charged despite
automatic generator lock. Program no. 2208 is used to set whether the
boiler takes part in the full charging or not.
Off: The boiler does {1}not{2} take part in the full charging of the buffer
storage tank.
On: The boiler takes part in the full charging of the buffer storage tank.
For more information, see
Full charging (4810), page 110
Setpoint min (2210) andSetpoint max (2212)
As a protection function the boiler temperature setpoint can be limited
below by the minimum setpoint (prog.no. 2210) and above by the
maximum setpoint (prog.no. 2212).
Setpoint manual control (2214)
Temperature to which the boiler is controlled in manual control mode.
