5.1.5 Combined use with Centralized Controllers
The combined use of the wiring adaptor for electrical appendices (2) and the centralized
controllers is enabled by the setting method shown below under the limited conditions.
Setting method
Cut the spare jumper (J5) connected to wiring adaptor for electrical appendices (2). (If the
use conditions shown below are not satisfied, however, the adapter may not normally
function.)
Use conditions
1. If the wiring adaptor for electrical appendices (2) is used by following methods, the combined
use will be enabled.
• Operation and malfunction with the wiring adaptor for electrical appendices (2)
• Forcedly thermostat OFF control with the wiring adaptor for electrical appendices (2)
(For mode settings, only use the input B in Positions C and E.)
• Temperature setting shift control with the wiring adaptor for electrical appendices (2)
(For mode settings, only use the input B in Positions D and F. This control, however, is
disabled in combined use with the temperature setting unit (DPF201A53).)
• The operation mode of the centralized controllers is set to "Individual (last pressing
priority)" and the control mode of the wiring adaptor for electrical appendices (2) is also set
to "Individual (last pressing priority)".
