• Relay 1 and 2 behavior are opposite of those above
Relay 1 is on when ON is set by System controller, ME remot controller or MA remote controller,
and off when OFF is set by these controllers. Whwn 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 °C (2 °F), 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.
Relay 1,2:
