4 S1S is factory set to OFF. Set to ON or REMOTE to operate.
5 Use a voltage-free contact for microcurrent (≤1 mA,
12 V DC). For more information about the remote switches,
see details in "14.6.1 Low voltage wiring – Outdoor
unit" [ 4 28].
6 Output (caution, warning, run, operation) is 220-240 V AC,
with a maximum load of 0.5 A.
7 For more information about the BS1~BS3 push buttons and
the DS1+DS2 DIP switches, see
settings" [ 4 33].
8 Do not operate the unit by short-circuiting protection devices
(S1PH, S2PH and S3PH).
