Several wiring possibilities
Option
Not mounted in switch box
Wiring depending on model
PCB
Notes:
1 Symbols: see above.
2 Refer to the installation or service manual on how to use
BS1~BS4 push buttons and DS1‑1~DS1‑2 switches.
3 Do not operate the unit by short-circuiting protection device
S1PH.
4 The capacity of this contact is 220~240VAC – 0.5A (total of
caution output, warning output, run output, and operation
output).
5 The initial setting is "0" (OFF). To operate, set to
"1" (REMOTE) or "2" (ON).
6 To use the remote switch, use a voltage-free contact for
microcurrent (<1mA - 12VDC). For instructions on how to
use the remote switch, refer to the technical engineering data.
7 The initial state of SW1 is "open" (normal mode). To activate
low‑noise mode, close the contact.
