5.1 DIP Switch Functions
Located on the FTC printed circuit board are 4 sets of small white
switches known as DIP switches. The DIP switch number is printed
on the circuit board next to the relevant switches. The word ON is
printed on the circuit board and on the DIP switch block itself. To
move the switch you will need to use a pin or the corner of a thin
metal ruler or similar.
DIP switch settings are listed below in Table 5.1.1.
Before changing any switch settings, ensure the power supplies to
both cylinder unit and outdoor unit are turned OFF.
Before changing the DIP switch setting, confi rm that the power
supply earth cable is securely connected and prevent the FTC
from being applied with static electricity (e.g. touch a case body
etc.). Otherwise, it may cause a failure of the FTC due to the static
electricity.

Note:
*1. For safety reasons, this function is not available for certain errors. (In that case, system
operation MUST be stopped and only the water circulation pump keeps running.)
*2. Space heating and DHW can be operated only in indoor unit, like an electric boiler. (Refer
to "5.4 Indoor unit only operation".)
*3. If emergency mode is no longer required, return the switch to OFF position.

Ensure to wire thermistor wirings away from the power line and/or
OUT3 to 13 wirings. Do not splice the wiring to extend or shorten it,
otherwise this could affect correct monitoring of each temperature.
If the wiring is too long, bundle it with a strap to adjust the length in
the cylinder unit.(see the photograph on the right)
*1. The maximum length of the thermistor wiring out of the cylinder
unit is 5 m. When the wires are wired to adjacent terminals, use
ring terminals and electrically insulate the wires.
When the wires are wired to adjacent terminals use ring terminals
