 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 (2 positions).
• 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.

position hot water module output signal functions. The maximum current output signal, from each of the output signal
function wirings, is 16 mA. Please ensure the rated current of the relay coil is less than 16 mA to avoid damage to
