SWITCH ON CIRCULATION
The circulation pump WWC is activated via a brief tapping process. If
the flow rate [V] is > 0 for a short time, WWC is active for a period of
time ZIR10 RUNTIME CIRC.PULSECON. WWC is then blocked for the
period of time ZIR11 OFFTIME. The runtime must be adapted to the
volume of the pipe network in order to make it possible to heat the
circulation pipe.
Under ZIR12, each mode can be temporally restricted by means of a
weekly time program with multiple switching phases. During "POWER
OFF TIME", the circulation pump is controlled by means of tap support.
As an option, the circulation pump can be controlled via the active
circulation mode or via tap support when the water tapping is active.
Whether circulation mode is active during tapping can be set under
ZIR13 CIRC. MODE WHEN TAPPED:
n
0: on Circulation mode is always active during tapping
n
1: off Circulation mode is always inactive during tapping
If the ZIR CIRCULATION MODE option is active, the tap support function
is automatically active. This function improves the quality of control
at the fresh water station. If tapping is active and the flow rate is
greater than STE15 MIN FLOW RATE, but lower than ZIR08 MIN FLOW
TAP SUPPORT, the circulation pump WWC becomes active in order to
increase the flow rate. If the tapping volume increases and exceeds
the switch-off threshold ZIR09 MAX FLOW TAP SUPPORT, the circulation
pump WWC is stopped.
If the tapping volume increases and exceeds the switch-off threshold
ZIR09 MAX FLOW TAP SUPPORT, the circulation pump WWC is stopped.
This value can be set in l/min under ZIRK08 MIN FLOW TAP SUPPORT.
The maximum flow rate ZIR09 MAX FLOW TAP SUPPORT is calculated in
l/min from the circulation volume ZIR07 FLOW RATE CIRCULATION plus
the minimum flow rate ZIR08 MIN FLOW TAP SUPPORT.
The circulation volume ZIR07 FLOW RATE CIRCULATION is the
throughput when the WWC circulation pump is active and there is no
tapping.
