5. Dip Switch setting
5.1 DIP Switch Functions
Located on the FTC printed circuit board are 5 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.
Only an authorised installer can change DIP switch setting under one’s own re-
sponsibility according to the installation condition.
Make sure to turn off both indoor unit and outdoor unit power supplies before
changing the switch settings.
For multiple outdoor units control with FTC (slave), see section 9.3.2.

Note: *1. When the FTC unit is connected with a SUHZ-SW outdoor unit of which maximum outlet water temperature is 55ºC, DIP SW1-2 must be changed to
OFF.
*2. External output (OUT11) will be available. 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.)
*3. This switch functions only when the cylinder unit is connected with a PUHZ-FRP outdoor unit. When another type of outdoor unit is connected,
the heating mode function is active regardless of the fact that this switch is ON or OFF.
*4. Space heating and DHW can be operated only in indoor unit, like an electric boiler. (Refer to "5.7 Indoor unit only operation". )
*5. If emergency mode is no longer required, return the switch to OFF position.
*6. Active only when SW3-6 is set to OFF.
*7. SW4-2 is available only when SW4-1 is ON.
