Premium Zoning Kit Notes - Hitachi airCore 700 Installation & Maintenance Manual

INSTALLATION & MAINTENANCE MANUAL
NOTES:
•
C8=00 is the factory default setting. If C8 is left unchanged, the system will sense the conditioned
space temperature from only one point (i.e.the sensor in the return air) and not from the individual
zones as intended.
•
If remote temperature sensors are used, they must be plugged into the Zone Interface Box and not
into the indoor unit.
(2) Indoor Unit ESP Setting
NOTES:
•
Please use auto ESP setting mode or manual ESP setting mode in Indoor Unit ESP setting, and
correctly set the ESP value, otherwise zone airflow volume may be influenced.
•
Do not operate Indoor Unit auto ESP function when system starting.
