Nibe AMS 10-16, Installation And Maintenance Instructions Manual

Page: 38 / 104

Climate system 2:
An external contact function can be connected to HBS 16
to change the flow temperature and in doing so change
the room temperature, for example, a room thermostat
or a timer. The contact must be potential free and non-
locking and connected to terminal block X1:14 and X1:15
on the current limiter board (AA22).
When the contact is closed, the heating curve offset is
changed by the number of steps shown here. The value is
adjustable between -10 and +10. The value for the change
is set in menu 3.5, "External adjust. 2".
Contact for activation of “Extra hot water”
An external contact function can be connected to HBS 16
for activation of the “Temporary extra hot water” function.
The contact must be potential free and non-locking and
connected to terminal block X6:1 and X6:2 on the current
limiter board (AA22).
When the contact is closed for at least one second, the
“Temporary Extra hot water” function is activated. An
automatic return to the previously set function occurs after
3 hours.
Alarm outputs
External indication of common alarms is possible through
the relay function on the current limiter board (AA22),
terminal block X2:1–2.
Electrical circuit diagram on page 67 shows the relay in
the alarm position.
When switch (SF1) is in the "0" or “ ” position the relay
is in the alarm position.
Docking specific connection
HBS 16 is prepared to control an external circulation pump
(GP10), external shunt (QN11), exchange valve for cooling
(QN12), as well as external addition e.g. oil, gas or pellets.
External circulation pump (max 50W)
Connect external circulation pump (GP10) to terminal
block X3:1 (230 V), X3:4 (N) and X3:5 (PE).
The circulation pump (GP10) is active when the circulation
pump (GP1) in HBS 16 is active.
The accessory HR 10 can be used if the connection output
exceeds 50W. See section Component positions on page
76.
External shunt (accessory)
Connection and function are described in the Installation
instructions for accessory ESV 28.
Shuttle valve, cooling (accessory)
Connection and function are described in the Installation
instructions for accessory VCC 28.
External addition
HBS 16 can control an external addition.
Sensor BT19 must be moved to sensor output BT24
between the docking connections XL8 and XL9 on the
tank (does not apply to solar power or wood fired docking).
See section Component positions on page 76.
Ext. 1 step

Remove the strap on terminal block X3:2 and X3:3.
See section Component positions on page 76 and
section Electrical circuit diagram on page 67.
2.
Connect the addition's phase to terminal block X3:2
(230 V) and X3:4 (N) (max 0.2 A).
3.
Use the accessory HR10 when the need for potential
for signal and/or when controlling external charge
pumps.
