F Cylinder Primary Pump Enable - Viessmann VITOTRONIC 200 Service Instructions Manual

601F Cylinder primary pump enable

Enables the circulation pump on the DHW side for
DHW heating in the cylinder loading system (cylinder
loading pump); connection to contact 224.6 on the
expansion PCB
Note
If the cylinder loading pump is connected to contact
211.4, it does not need to be enabled with this parame-
ter.
6020 Operating mode cylinder primary pump
Switching the cylinder loading pump and type of speed
control.
Note
If no cylinder loading pump is available, this parameter
enables the operating mode of the secondary pump to
be set for DHW heating.
Requirement: "Operating mode secondary pump
7340" is set to "4".
Value Meaning
"0" No switching via PWM signal, e.g. with stand-
ard circulation pump (multi stage)
"1" Standard mode: ON/OFF; switching by PWM
signal
"2" Operation at a fixed specified speed; switch-
ing by PWM signal
6040 Enable elec. heating/ext. HS for reheating only
Applies to instantaneous heating water heaters,
immersion heaters and external heat generators.
6060 Blocking time DHW heating
Once the DHW has been heated to the currently appli-
cable set temperature, the DHW cylinder will not be
heated for the specified period. This applies even if the
cylinder temperature falls below the switch-on point
during this period.
!
Value Meaning
"0" No cylinder loading pump installed.
"1" Cylinder loading pump is activated.
!
Value Meaning
"3" Variable speed operation: Switching by PWM
signal.
Speed is adjusted via output control (PID con-
troller), so that the set cylinder temperature is
reached quickly.
"4" Do not adjust.
!
Value Meaning
"0" For DHW reheating, booster heaters enabled
for this can be switched on in parallel to the
heat pump.
"1" The compressor stops when the heat pump
control unit issues a demand for DHW reheat-
ing to one of the enabled booster heaters.
!
Note
■ If too long a blocking time is set and DHW consump-
tion is high, the cylinder temperature may fall too far.
If "Max. interruption DHW heating 6061" is set to a
■
shorter period than "Blocking time DHW heating
6060", the set blocking time will have no effect. Pro-
vided that the stop temperature for the DHW cylinder
is undershot, DHW heating will start once the "Max.
interruption DHW heating 6061" has expired. This
applies even if the start temperature for DHW heat-
ing has not been undershot.
