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 54.
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
connected 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 54.
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
savings 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 set-
table in menu 4.1.5).
(A = SG Ready A and B = SG Ready B )
NIBE™ F370
Switch for +Adjust
Using +Adjust, the installation communicates with the
underfloor heating's control centre* and adjusts the
heat curve and calculated supply temperature accord-
ing to the underfloor heating system's reconnection.
Activate the climate system you want +Adjust to affect
by highlighting the function and pressing the OK but-
ton.
*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. Version can be
checked in menu 3.1 under "input version"
respectively "display version". New software
can be downloaded for free from
www.nibeuplink.com.
NOTE
In systems with both underfloor 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
potential-free switch function to the input selected in
menu 5.4, see page 54.
A closed switch results in blocked heating operation.
NOTE
When heat blocking is activated, the min.
supply 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 54.
A closed switch results in blocked hot water operation.
Contact for activation of "temporary lux"
An external switch function can be connected to F370
for activation of the hot water function "temporary
lux". The switch must be potential-free and connected
to the selected input (menu 5.4, see page 54) on ter-
minal block X6 on the input board (AA3).
