• 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.
"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 connect-
ing potential-free switch functions to two inputs selec-
ted 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 )
• +Adjust
Using +Adjust, the installation communicates with
the underfloor heating's control centre* and adjusts
the heating curve and calculated supply temperature
according to the underfloor heating system's recon-
nection.
Activate the climate system you want +Adjust to affect
by highlighting the function and pressing the OK but-
ton.
*Support for +Adjust required

Caution
In systems with both underfloor 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 F730
for blocking various functions. The switch must be po-
tential-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 (blocking of heating demand)
• internally controlled additional heat
• compressor
• tariff blocking (additional heat, compressor, heating
and hot water are disconnected)
