• SG ready
Caution
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 board
(AA3) or to terminal block X2.
"SG Ready" is a smart form of tariff control, through
which 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 se-
lected 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).
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 )

Caution
In systems with both under floor heating and
radiators, NIBE ECS 40/41 should be used
for optimum operation.
External blocking of functions
An external switch function can be connected to
SMO 40 for blocking various functions. The switch must
be potential-free and a closed switch results in blocking.
NOTE
Blocking entails a risk of freezing.
Functions that can be blocked:
• hot water (hot water production). Any hot water circu-
lation (HWC) remains in operation.
• heating/cooling (production and distribution)
• additional heat (additional heat is blocked)
• compressor in heat pump EB101 and/or EB102
• tariff blocking (additional heat, compressor, heating,
cooling and hot water are disconnected)
• block OPT10 (Can be selected when the accessory
OPT10 is activated.)
• block AZ10, blocks the compressor in F135. (Can be
selected when the accessory F135 is activated.)
Possible selections for AUX output
It is possible to have an external connection through the
relay function via a potential-free switching relay (max.
2 A) on the input board (AA3), terminal block X7. The
function must be activated in menu 5.4.
