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.

NOTE
Auxiliary relays (locally procured) must be connected to output signal function wirings to allow connection to the
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
the hot water module P.C. board.
▼Output function wire
CAUTION
Output signal functions are separated from primary basic insulation.
• To prevent noise trouble, use 2-core shield wire.
• Determine the wire length between the hot water module output signal function terminal block and the relay up
to 2 m.
• Locally procure and install protective devices such as the heater and pump.
