Do not insert more than one
connecting cable into each
terminal of TB571 and TB530.
● For TB571 and TB530, insert wiring after inserting the flathead screwdriver into the terminal.
●
Appropriate electric wire for TB571 and TB530 is as follows. Stranded wire: 0.3 mm
2
to 1.25 mm
2
[AWG 22 to 16] Solid wire: ø 0.4 mm to ø 1.2 mm
[ø 1/64 in. to ø 3/64 in.]
● Peeling dimension of the electric wire for TB571 and TB530 is 7 mm to 10 mm [9/32 in. to 25/64 in.].
● Wiring length from the interface to Relay 1 and Relay 2 should be less than 50 m [164 ft.].

Notes
•
Connecting terminal TB530 for power supply is polarized, so confirm proper polarity of the terminals before connecting.
• Do not connect DC 12 V from the DC power supply to TB571.
• Confirm polarity when using a diode built-in relay. C of TB571 is electropositive potential
, and R1 and R2 are negative potential .

Relay 1 is on when ON is set by System controller, ME remote controller or MA remote controller, and off
when OFF is set by these controllers.
When room temperature becomes the set temperature or lower in the heating (automatic heating) mode,
the Relay 2 (heater) turns on. When a mode other than heating (automatic heating) or OFF is set by System
controller, ME remote controller or MA remote controller, or when room temperature becomes higher than
the set temperature + 1 ºC (2 ºF), the Relay 2 (heater) turns off.
* This function is to run the heater instead of the air conditioner in the heating mode. The air conditioner
stops in the heating mode.
Do not use the remote controller attached to the air conditioner. If you use it, the operation may not reflect
the setting.
The position of detecting the room temperature is where MA remote controller is put, so make sure to
connect it to the interface unit.
Please use the cable of 0.5 mm
2
[AWG 20] or more.
The cable must fit into TB530 and meet DC 12 V power supply.
