Wire connection
REQUIREMENT
• Connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
• Pass the wires through the bushing of wire connection holes of the hot water module.
• Keep a margin (Approx. 100 mm) on a wire to hang down the electrical control box at servicing or other purpose.
• The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
• Remove the front panel of the hot water module by taking off the mounting screws (8 positions).
• Wrap a heat insulation (locally procured) around the power supply to fill the gap between cord and port cap.
• Wrap a heat insulation (locally procured) around the control wires and external signal wires to fill the gap between
cord and port cap.
• Tighten the screws of the terminal block, and fix the wires with cord clamp attached to the electrical control box.
(Do not apply tension to the connecting section of the terminal block.)
• Mount the front panel of the hot water module without pinching wires.

Wiring for Flow selector unit (FS unit) for SHRM-e
Connect communication wire of FS unit to terminal A, B (no polarity) of Hot Water Module,
when the Hot Water Module connects to SHRM-e system.
NOTE
• In case of connecting at least one Hot Water Module in SHRM-e system, all of FS units in the system should be
Single port type FS unit (long piping model) or Multiport type FS unit.
Remote controller wiring
• Strip off approx. 9 mm the wire to be connected.
