15.2 Circulator Blower
This air handler is equipped with a variable speed circu-
lator blower. This blower provides several automatical-
ly-adjusted blower speeds. For heater kit installation, it is
important to set the capacity of the electric heater at two
locations of communication thrermostat and DIP Switch.
Setting with communication thermostat:
For a detailed procedure of thermostat heater kit capacity
selection process, please visit the Daikin One website at
http://www.daikinone.com
Setting with DIP Switch:
In the event of loss of communication, emergency mode
can be activated. In emergency mode operation, heater
kit selection will be driven by the DIP Switch (s9, S10, S11
and S12) selection from the control board. Select the DIP
Switch settings in accordance with Tables 9 and 10 (see
table 9 for valid settings). Indoor blower airflow (CFM)
for a particular heater kit selection can be checked with
the STATUS menu of communication thermostat or with
the 7-segment display on the control board. (See section
SETTING THE MODE DISPLAY).
NOTE:
Upon start up in communicating mode the circuit
board may display an “Ed” error. This is an indication
that the DIP switches on the control board need to be
configured in accordance with the Electric Heating Airflow
Table. Configuring the DIP switches and resetting power
to the unit will clear the error code.
CAUTION
Do not change any other dip switches other than
S9 to S12. Incorrect settings may cause any error.
For default setting, see Figure 15.
15.3 Motor Orientation
If the unit is in the upflow position, there is no need to
rotate the motor. If the unit is in the downflow position,
loosen motor mount and rotate motor as shown in the
Mo-
tor Orientation,
Figure 17.
Be sure motor is oriented with
the female connections on the casing down. If the motor
is not oriented with the connections down, water could
collect in the motor and may cause premature failure.
15.4 Accessory Contacts
The control is equipped with an Accessory Relay and a
pair of ¼ inch accessory terminals which is normally open,
labeled ACC-IN and ACC-OUT (see accessory contacts
graphic). The Accessory Relay can be configured to close
with humidification functionality or to close anytime the
blower is running. A closed relay means the two terminals
will have continuity between them (the control does not
energize these contacts). The set-up menu is where this
configuration takes place.
