MOTE SENSOR
This product does not include an air inlet thermistor.
It uses a remote controller thermistor for control purposes.
For this reason, it is necessary to install an optional remote
thermistor in the following cases:
When the remote controller will be installed at a location
•
where it cannot accurately measure the indoor temperature.
When using a remote controller without a built-in thermistor
•
(simple remote controller, wireless remote controller, no
remote controller).
When using an optional remote sensor, change the settings as
described Table 5:
(The SECOND CODE NO. is set to “03” when shipped.)
