(1) Are the indoor and outdoor communication lines of the header unit connected to the U1/U2 terminals?
(2) Is the relay connector between the U1/U2 terminal and the U3/U4 terminal removed? (Set up at
shipment from the factory)
(Keep the relay connector disconnected before address setup.)
(3) Is the communication line between outdoor units connected to the U5/U6 terminal?
(4) Is the communication line of the central control system connected to the header unit U3/U4 terminals
of each refrigerant line?
(The communication line of the central control system may be connected to the communication lines
of the indoor/outdoor communication lines.)
(5) Is the terminal resistance (SW30-bit 2) on the interface PC board of the header unit turned on? (Set
up at shipment from the factory)
* After address setup and test operation check, turn on the SW30-bit 2 of the header unit for the
smallest line address, and turn off SW30-bit 2 of the header unit for other refrigerant lines.
(See “7-4-3. Address Setup Procedure”)
(6) Is the end terminal of the shield wire open?
(7) Is the end terminal of the shield wire earthed at the header unit side?
(8) When the refrigerant line and the central control system of the DI-SDI series are connected:
Are Network adapter (TCB-PCNT30TLE2) correctly connected?
When the DI-SDI series operates with group, twin, or triple operation, are the adapters connected
to the header unit of the indoor unit?
