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, which al-
lows your electricity supplier to affect the indoor, hot
water and/or pool temperatures (if applicable) or
simply block the additional heat and/or compressor
in GreenMaster-HP 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).
Closed or open switch means one of the following:
–
Blocking (A: Closed, B: Open)
"SG Ready" is active. The compressor in GreenMaster-
HP and additional heat are blocked.
–
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 ac-
cording to the underfloor heating system's reconnec-
tion.
Activate the climate system you want +Adjust to affect
by highlighting the function and pressing the OK but-
ton.
