Caution
Some of the following functions can also be ac-
tivated and scheduled via menu settings.
Possible selection for AUX inputs
Switch for external blocking of addition and/or
compressor
Blocking for addition heat and compressor is connected
on two different AUX inputs.
If external blocking of additional heat and/or compressor
is wanted, this can be connected to terminal block X6
on the input board (AA3), which is positioned behind
the front cover.
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 48.
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 48.
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 and hot water
temperatures or simply block the additional heat and/or
the 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 48.
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).
(A = SG Ready A and B = SG Ready B )
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” respectively
”display version”. New software can be down-
loaded 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.
Switch 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 48.
A closed switch results in blocked heating operation.
NOTE
When heat blocking is activated, the min. supply
line does not apply.
