T10 connector (CN061).

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: CN061 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 300msec. 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): 12V output during the unit ON / no output at OFF
4. 5-6 (static output): 12V output when some errors occur / no output at normal

NOTE: The wire length from indoor unit to the relay must be within 2,0m. Pulse signal changeable to static by cutting jumper JP001.
a. 300m or more. / b 1-2 (pulse input). / c. 4-5 (output). / d. Unit condition. e. T10 (yellow).

Usage example.

Forced OFF control.
Term 1 and 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 and 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).

a. ON / OFF. / b. Common. / c. Prohibit. / d. Operation output 12V DC. / e. Common. / f. Output alarm 12V DC. / g. Relay 12V DC.


Operation ON / OFF signal output.
Condition:

4-5 (static output): 12V output during the unit ON / no output at OFF.

Note: The wire length from indoor unit to the Relay must be within 2,0m. Pulse signal changeable to static by cutting jumper JP001.
* PACi NX Series is not compatible.

Fan drive connector (CN032).

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 (CN032).

Operating the ventilation fan from the remote controller:
Start / stop of external ventilation and total heat exchanger fans. Works even if indoor unit is stopped. In case of group control > all fans will operate; no individual control.

a. External fan ON / OFF / b. FAN DRIVE (2 plug (white)). / c. Indoor unit control PCB. / d. Relay (field supply). / e. To external-control input terminal on ventilation fan.

Option connector (CN060) output external signals.

PAW-OCT

Panasonic has developed an optional accessory (consisting of plug wires) called PAW-OCT to enable an easy connection to this Option Connector (CN060).

With the combination of the T10 and the option CN060 an external control of the indoor units is possible!

6P (white): Outputs external signals as shown in the figure below.
a. OPTION (white). / b. Indoor unit control PCB (CR1). / c. Relay (12V DC, field supply)*. / d. Fan signal. / e. Heat start signal. f. Cool start signal. / g. Thermostat signal. / h. Defrost signal.
* The relay must be installed at a distance of 2m or less from the PCB.

EXCT connector (CN073).

PAW-EXCT

Panasonic has developed an optional accessory (consisting of plug wires) called PAW-EXCT to enable an easy connection to this EXCT Connector (CN073).
A) With static input.
> STATIC INPUT > THERMO OFF > ENERGY SAVING
2P plug (red): Can be used for demand control. When input is present, forces the unit to operate with the thermostat OFF.

Note: The length of the wiring from the indoor unit control PCB to the relay must be 2m or less.

B) Example: In connection with a refrigerant sensor.
· Signal from leakage detector: non voltage, static.
· Indoor unit setting: Code 0b > 1
· Connector for leak detector: EXCT
· Outdoor unit setting: Code C1 > 1 power output if alarm from O2 connector 230V. Code C1 > 2 power output if alarm from O2 connector 0V
· Displayed alarm message P14
