PARAMOUNT
Connect header pump for X1/M5:
If hydraulic schematic requires a header pump
connect its plug to X1/M5. A heating circuit pump
(CTC) is connected to exit M1.
Programming header pump function:
-Program No. 615;Code 9
- 1. Set program No. 615
to Code 9
-Program No. 632 (see below):
Set bits b0 to b3
according to when the header pump has to start
operating.
618 (KonfigEingangR):
•
618 = 0 (factory setting): No function
•
618 = 4: Temperature setpoint
The temperature setpoint is given by an external
analogue signal (0-10V).
The maximum setpoint is set at parameter No.622.
The setpoint can be between 5 and 100°C (limited by
the max boiler temperature of 85°C). 5°C is the
minimum threshold, i.e. the boiler is switched on at
6°C and switched off at 4°C
The heat demand is valid for HC 1. An additional
heat demand (e.g. from a VTC, is accepted, the
boiler temperature setpoint is then the maximum of
the two heat demands).
•
618 = 5: Output setpoint
The analogue signal (0-10V) gives the output
setpoint. This analogue signal is handed over to the
boiler control BMU and is interpreted as a percentage
value on the specific output range of the boiler. The
minimum threshold switching on and off the boiler
can be set at parm. No. 623. The range between min.
and max. value is calculated into a power signal of 0-
100%. If the analogue signal is higher than the
minimal value, the boiler operates at min. output. At
the max. value, the boiler operates at max. output. If
the analogue signal is below the minimum threshold,
the output is not active. Other settings of Parameters
No. 618 are not possible with the CISP connected.
If other clip in modules are connected, see the
specific installation manual for other setting
possibilities.
619
– 621
(KonfigAusgang1R to
KonfigAusgang3R):
The CISP clip-in has 3 outputs that can be
programmed.
The setting possibilities are the same as for param.
No. 615, codes 0-12.
Factory-presettings are:
619 (output 1) = 2 (alarm signal)
620 (output 2) = 3 (operating signal)
621 (output 3) = 4 (no function)
622 (TanfoExtMax) Temperature setpoint:
The
heat demand is given by an analogue signal via input
N11, see wiring diagram. Set this parameter to define
the max. value of heat demand (Factory setting
100°C). Only applicable if param. No 618 = 4.
623 (PanfoExtSchwelle) Heat output setpoint:
The
relative heat output is given by an analogue signal
via input N11, see wiring diagram. Set this
parameter to define the minimum threshold from
which on the heat demand is accepted (in % of the
max. value of the analogue signal. Only applicable if
parameter No.618 =5).
632 (WanfoQ8) Heat demands to be satisfied by
primary loop pump
(Only if param. 615 or 619 are
set to "9"): To define which heat demand will make
pump M5 start. The activation is independent from
the hydraulic system and can be used for both
central heating and DHW generation.
b0.1: M5 ON for zone control ZR EC 1 / 2
b1.1: M5 ON for heating circuit 2 (VTC)
b2.1: M5 ON for heating circuit 1 (CTC)
b3.1: M5 ON for DHW generation
Note: These bits can be set in any combination
724 (MmiStatus) Current summer/winter setting
for boiler module:
The current summer/winter
setting for the boiler module is displayed:
724.0 0 or 1: Current summer/winter setting
(Value 0 = Summer, Value 1 = Winter)
724.1 0 or 1: Current summer/winter switchover
(Value 0 = Manual, Value 1 = Automatic)
755 (IonStrom) Ionisation current actual value
display:
The current ionisation current is indicated
when the burner is in operation.
Hot-water control:
The hot water requirement has
priority over heat demand from a heating circuit.
Automatic day heat limit:
The automatic day heat
limit is effective only when the outdoor temperature
sensor is connected.
This is a rapid-acting economy function, which
switches off the boiler when the mixed outdoor
temperature is higher than the room temperature
setting (standard or reduced)
The boiler switches back on when the mixed outdoor
temperature is 2K below the room temperature
setting.
For outdoor temperature control with no room
influence, the actual room temperature is taken into
consideration.
The automatic day heating limit is active, “ECO”
appears on the display of the room control module
RRG.
