Outline of D-<strong>BACS</strong> System<br />
3.2 Main Specifications and Functions of the Equipment<br />
For more effective localized environmental control <strong>Daikin</strong> offers various control systems such as single or double remote<br />
control or centralized control. This enables the construction of a variety of operational control systems which can be<br />
adapted for various uses from remote control to building automation.<br />
Control by Remote Controller<br />
Control Method Objective / Use<br />
Local operation of<br />
remote controller<br />
Remote operation<br />
of remote<br />
controller<br />
2 remote control<br />
Group control ∗1<br />
∗1<br />
Group control by 2<br />
remote controllers<br />
Forced OFF<br />
command from<br />
outside<br />
Combining control<br />
by remote<br />
controller<br />
Example of typical<br />
use<br />
For control from<br />
distant place<br />
For control from 2<br />
places (distant or<br />
local)<br />
For the control of<br />
plural indoor units<br />
on a floor at the<br />
same time<br />
For above control<br />
from distant place.<br />
Forced OFF for<br />
forgetting to turn<br />
equipment off, or<br />
in times of an<br />
emergency.<br />
Operation of other<br />
equipment<br />

� In the right<br />
figure, a wired<br />
remote<br />
controller is<br />
used for the<br />
system<br />
configuration.<br />
However, the<br />
same control is<br />
available if the<br />
controller is<br />
replaced by a<br />
wireless.<br />
� When using<br />
two remote<br />
controllers, it is<br />
not possible to<br />
set both of<br />
them for<br />
wireless<br />
remote<br />
controllers. Be<br />
sure to set at<br />
least one of<br />
them for a<br />
wired remote<br />
controller.<br />
Function<br />
Operational functions<br />
� Start/Stop (ON/OFF)<br />
� Operation Mode Selection<br />
� Temperature setting<br />
� Timer setting (Settings in units of 1 hour up to<br />
a maximum of 72 hours)<br />
� Air flow setting<br />
� Air flow direction adjustment (Swing flap)<br />
Indication function<br />
� Operating display<br />
� Program dry function display<br />
� Defrost/Hot start display<br />
� Filter sign<br />
� Temperature setting display<br />
� Timer display<br />
� Air flow display<br />
� Abnormal operation display<br />
∗ In case of group control all the indoor units in<br />
the system are set to the same value and<br />
each unit is controlled individually by its<br />
internal thermostat. (Not by the thermostat<br />
equipped in remote controller) In commond<br />
case of double remote control the last<br />
command priority. (Selection between main<br />
and sub controller is essential)<br />
Note)<br />
Some functions cannot be set depending on the<br />
shape of indoor unit.<br />
� Forcibly stops indoor unit operation by<br />
command from outside.<br />
� During remote controller group control, input a<br />
command from outside to any one of the<br />
indoor units.<br />
� Operates HRV in accordance with indoor unit<br />
operation.<br />
Standard Number of<br />
Units<br />
1 remote controller<br />
controls 1 indoor unit<br />
2 remote controllers<br />
control 1 indoor unit<br />
1 remote controller<br />
controls up to 16<br />
indoor units<br />
simultaneously<br />
2 remote controllers<br />
control up to 16<br />
indoor units from 2<br />
different places<br />
simultaneously<br />
Same as the number<br />
of units controlled by<br />
remote controller<br />
Same as the number<br />
of units controlled by<br />
remote controller<br />
∗1 In case of group control, the remote controller used as master control must be selected with auto-swing function<br />
(BRC1A61). When the group has cassette (FXC (Q)), FXF (Q)) or ceiling suspended (FXH (Q)) or cassette corner<br />
(FXK (Q)) or wall mounted (FXA (Q)) models.<br />
∗2 In case of using BRC2A51 (Simplified Remote Controller) to Heat Recovery Series, be sure not to use this<br />
independently. Use with other remote controllers (BRC1A51 · 52, BRC1C62 or KRC19-26A or DCS302A51).<br />
