T10 connector (CN015)
CZ-T10: Panasonic has developed an optional accessory (consisting of plug + wires) called CZ-T10 to enable an easy connection to this T10 connector.
Connecting an ECOi indoor unit to an external device is easy. The T10 terminal featured in the electronic circuit board of all indoor units enables digital connection to external devices.
T10 terminal Specification (T10: CN015 at indoor unit PCB)
  • Control items:
  1. Start/stop input
  2. Remote controller prohibit input
  3. Start signal output
  4. Alarm signal output
  • Condition
  1. 1-2 (Pulse input): Unit ON/OFF condition switching with a pulse signal. (1 pulse signal: shortage status more than 300 msec. or more)
  2. 2-3 (Static input): Open / Operation with Remote is permitted.(Normal condition) Close / Remote controller is prohibited.
  3. 4-5 (Static output): 12 V output during the unit ON. / No output at OFF.
  4. 5-6 (Static output): 12 V output when some errors occur / No output at normal.

Example of wiring
A. 300 ms or more
B. 1-2 (pulse input)
C. 4-5 (output)
D. Unit condition
NOTE: The wire length from indoor unit to the Relay must be within 2.0 m. Pulse signal changeable to static with JP cutting. (Refer to JP001)
E. T10 (yellow)
Usage Example
Forced OFF control
  • Term 1 & 2: Free contact for ON/OFF signal (cut *JP1* for static signal) when the hotel card is it connected the contact must be close (the unit can be used).
  • Term 2 & 3: Free contact to prohibit all function in the remote controller install in the room when the hotel card is it removed the contact must be closed (the unit can not work).

Operation ON/OFF signal output
  • Condition:
4-5 (Static output): 12 V output during the unit ON / No output at OFF

Example of wiring
A. Terminal = T10
1. On / Off
2. Common
3. Proibit
4. Operation output +12 V DC
5. Common
6. Output alarm +12 V DC
B. Relay 12 V DC
C. T10 (yellow)
D. Indoor unit control PCB
E. Relay (Field supply)
F. Central control
NOTE: The wire length from indoor unit to the Relay must be within 2.0 m. Pulse signal changeable to static with JP cutting. (Refer to JP001)
Fan Drive Connector (CN017)
PAW-FDC: Panasonic has developed an optional accessory (consisting of plug + wires) called PAW-FDC to enable an easy connection to this Fan Drive Connector (CN017).
