INSTALLATION & MAINTENANCE MANUAL
NOTES:
•
C8=00 is the factory default setting. If C8 is le 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
Before operating Indoor Unit auto ESP function, please set all zone ON and
all zones’ airow tap to H tap rst. This can be done using "Turn on All Zones"
in Zone Installation Menu.
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 airow volume may be inuenced.
•
Do not operate Indoor Unit auto ESP function when system starting.
