Nibe F1155 Series Installer Manual page 27

The additional heat and/or the compressor are discon-
nected by connecting a potential-free switch function
to the input selected in menu 5.4, see page 51.
External blocking of addition and compressor can be
combined.
A closed contact results in the electrical output being
disconnected.
Contact for external tariff blocking
In those cases where external tariff blocking is used, it
can be connected to terminal block X6 on the input
board (AA3), which is positioned behind the front cover.
Tariff blocking means that the additional heat, the
compressor, the heating and hot water are blocked by
connecting a potential-free switch function to the input
selected in menu 5.4, see page 51.
Closed switch means that tariff blocking is activated.
NOTE
When tariff blocking is activated, the min.
supply line does not apply.
Switch for "SG ready"
NOTE
This function can only be used in mains net-
works that support the "SG Ready"-standard .
"SG Ready" requires two AUX inputs.
In cases where this function is required, it must be con-
nected to terminal block X6 on the input card (AA3).
"SG Ready" is a smart form of tariff control where your
electricity supplier can affect the indoor, hot water
and/or pool temperatures (if applicable) or simply block
the additional heat and/or compressor in the heat pump
at certain times of the day (can be selected in menu 4.1.5
after the function is activated). Activate the function by
connecting potential-free switch functions to two inputs
selected in menu 5.4 (SG Ready A and SG Ready B), see
page 51.
Closed or open switch means one of the following:
■
Blocking (A: Closed, B: Open)
"SG Ready" is active. The compressor in the heat pump
and additional heat is blocked like the day's tariff
blocking.
■
Normal mode (A: Open, B: Open)
"SG Ready" is not active. No effect on the system.
■
Low price mode (A: Open, B: Closed)
"SG Ready" is active. The system focuses on costs sav-
ings and can for example exploit a low tariff from the
electricity supplier or over-capacity from any own
power source (effect on the system can be adjusted
in the menu 4.1.5).
■
Overcapacity mode (A: Closed, B: Closed)
"SG Ready" is active. The system is permitted to run at
full capacity at over capacity (very low price) with the
electricity supplier (effect on the system is settable in
menu 4.1.5).

Switch for +Adjust
Using +Adjust, the installation communicates with the
underfloor heating's control centre* and adjusts the heat
curve and calculated supply temperature according to
the underfloor heating system's reconnection.
Activate the climate system you want +Adjust to affect
by highlighting the function and pressing the OK button.
*Support for +Adjust required
NOTE
+Adjust must first be selected in menu 5.4 "soft
inputs/outputs".
NOTE
Circuit board AA3 in the installation must have
at least "Input version・34 and the software
version must have "display version 5539 or later
for +Adjust to work. The version can be
checked in menu 3.1 under "input version" re-
spectively "display version". New software can
be downloaded for free from
www.nibeuplink.com.
NOTE
In systems with both under floor heating and
radiators, NIBE ECS 40/41 should be used for
optimum operation.
Contact for external blocking of heating
In those cases where external blocking of heat is used,
it can be connected to terminal block X6 on the input
board (AA3), which is positioned behind the front cover.
Heating operation is disconnected by connecting a po-
tential-free switch function to the input selected in menu
5.4, see page 51.
A closed switch results in blocked heating operation.
NOTE
When heat blocking is activated, the min. sup-
ply line does not apply.
Switch for external blocking of hot water
In cases where external blocking of hot water is used,
this can be connected to terminal block X6 on the input
board (AA3), which is positioned behind the front cover.
Hot water operation is disconnected by connecting a
potential-free switch function to the input selected in
menu 5.4, see page 51.
A closed switch results in blocked hot water operation.
Switch for external forced control of brine pump
In those cases external forced control of brine pump is
used, this can be connected to terminal block X6 on the
input board (AA3), which is positioned behind the front
cover.
