17 Function block: Service functions and general settings

2017-07-24

17.4.3  Pump kick

To prevent pump seizing during longer off periods (e.g. in the summer), a periodic
pump kick can be activated on operating line 175. The input is either 0 or 1:
0 =  no periodic pump kick
1 =  weekly pump kick

If the pump kick is activated, all pumps run for 30 seconds, one after the other,
every Friday morning at 10:00, independent of all other functions and settings.

17.4.4  Winter-/summertime changeover

Changeover from wintertime to summertime, and vice versa, takes place automati-
cally. If international regulations change, the dates need to be reentered. The date
to be entered is the earliest possible changeover date. Changeover always takes
place on a Sunday.

If the start of summertime is specified as the "Last Sunday in March", the earliest
possible changeover date is March 25. Then, the date to be entered on operating
line 176 is 25.03.
If no winter-/summertime changeover is required, the 2 dates must be set so that
they coincide.

17.4.5  Locking signal gain

Functions "Maintained boiler return temperature", "Protective boiler startup" and
"D.h.w. priority" use locking signals that are forwarded to the heat exchangers and
consumers. With the heat exchanger and consumer controllers, operating line 173
(locking signal gain) can be used to set how intensely these controllers shall
respond to locking signals. The locking signal gain is adjustable from 0% to 200%.

Setting

Response

0%

Locking signal is ignored

100%

Locking signal is adopted on a 1-to-1 basis

200%

Locking signal is adopted as a double signal

There are 2 types of locking signals:

  Uncritical locking signals
  Critical locking signals

The response of the consumers depends on the type of load.

Uncritical locking signals are generated in connection with d.h.w. priority (absolute
and shifting) and only act on the heating circuits.
The response of the heating circuit depends on the type of heating circuit:

  Heating circuit with mixing valve/2-port valve:

In the heating circuit, the flow temperature setpoint is reduced as a function of
the set locking signal gain. The mixing valve/2-port valve closes, the heating cir-
cuit pump continues to run

  Heating circuit with pump:

When the uncritical locking signal reaches a defined value, the heating circuit
pump is deactivated, independent of the set locking signal gain. In plants using a
diverting valve, the valve is driven to the d.h.w. position

Example:
