[2-32]
Forced, all time, power consumption limitation operation (no external
control adaptor is required to perform power consumption limitation).
If the system always needs to be running under power consumption
limitation conditions, this setting activates and defines the level
power consumption limitation that will be applied continuously. The
level is according to the table.

0 (default) Function not active.
1 Follows [2-30] setting.
2 Follows [2-31] setting.
[2-34]
Indoor unit fan tap setting.
Indoor units fan speed limitation related to connection capacity for
energy saving.
[2-34] Indoor unit fan tap setting
0 (default) Fan speed is limited to L tap when indoor units
capacity ≥ 130%.
1 In heating mode or simultaneous cool/heat
mode, fan speed is limited to L tap when indoor
units capacity ≥ 130%.
2 Fan speed follows the setting of remote
controllers (not limited by indoor units
connection capacity).
[2-42]
Interlock error operation setting.
Abnormal indication is enabled after constant time after a circuit
(S3S) of the interlock input opened.

Antifreeze type setting.
By changing this setting, you can extend the operation range at the
antifreeze side of the unit.
▪ Normal operation range at antifreeze side (default): for use with
water as heat source medium.
▪ Extended operation range at antifreeze side (default): for use with
antifreeze as heat source medium.
NOTE
By changing this setting to extended operation type,
propylene glycol or ethylene glycol must be used as heat
source medium to avoid freeze up of the antifreeze circuit
or unit itself (cf. operation range). Do not use water in this
case!
