Automatic switch to backup heat source operation

Back-up heat source operation (*1) will automatically run when the outdoor unit stops abnormally.

To enable the function, switch Dip SW 2-5 to ON.

During the back-up operation, an error code(s) and the contact number will be displayed alternately.

External output (OUT11) will be available.

To clear the fault(s), reset the power breakers on the indoor and outdoor units.

E6 to E9, ED, P6, P8, U1 to U8, UD, UE, UF, UL, UP
(*1) Prolonged running of the back-up operation may affect the life of the heat source.

(*2) For safety reasons, this function is not available for certain faults. (System operation must be stopped and only pump keeps running.)

6-13. Dip switch setting

Located on the FTC4 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 the table below.

Before changing any switch settings, ensure power supplies to indoor and out

door units are isolated/powered off.

Note:

1. When the cylinder unit is connected with a PUHZ-RP 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 opera-

tion 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 con-

nected, the heating mode function is active regardless of the fact that this switch is ON or OFF.

4. If emergency mode is no longer required, return the switch to OFF position.
