PACD011001C2 Test Operation
Test Operation Urban Multi “MX1, ME1 Series” Using R-22 121
Wiring to Indoor
Units
The terminals (F1, F2) of the control terminal block of the central remote controller and the terminals (F1,
F2) of indoor units for which a group No. has been set are wired as shown in the figure below. (There is no
polarity, so it doesn’t matter if F1 and F2 are wired inversely.)
∗
1. Connector for unification adaptor for computerized control (CN2)
∗
2. Forced OFF input (T1, T2)
Forced OFF input (no-voltage contact for micro-current) turns off all indoor units while the contact is
“closed.” Use a contact which guarantees min. applicable load of 16VDC, 10 mA.
∗
3. Power supply for schedule timer (D1, D2)
