Precautions on wiring of power supply
For connection of the field wiring to the mainswitch, use the
instruction as described below.

For other connections, use a round crimp-style terminal for
connection to the power supply terminal board. In case it cannot
be used due to unavoidable reasons, be sure to observe the
following instruction (e.g. connection of the earth wire).

- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the below figure.
Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
Over-tightening the terminal screws can damage the screws.
See the table below for tightening torques for the terminal
screws.

Attach an earth leakage circuit breaker and fuse to the power
supply line.
In wiring, make certain that prescribed wires are used, carry out
complete connections, and fix the wires so that outside forces
are not applied to the terminals.

NOTE
the heating and cooling schedule timers are never
available. Other schedule timers are not affected.
For more information on the schedule timers, refer
to the operation manual.
When a room thermostat is connected to the unit,
and the = button or o button is pressed, the
centralised control indicator e will flash to
indicate that the room thermostat has priority and
controls on/off operation and change over
operation.
