(17) Anomalous fan motor
(a)
After starting the fan motor, if the fan motor speed is 200min
-1
or less is detected for 30 seconds continuously and 4 times
within 60 minutes, then fan motor stops with the anomalous stop (E16).
(b) If the fan motor fails to reach at -50(FDU: -500)
min
-1
less than the required speed, it stops with the anomalous stop (E20).
(18) Plural unit control – Control of 16 units group by one remote control
(a
) Function
One remote control switch can control a group of multiple number of unit (Max. 16 indoor units). “Operation mode”
which is set by the remote control switch can operate or stop all units in the group one after another in the order of unit
No.
(1)
. Thermostat and protective function of each unit function independently.
Note (1) Unit No. is set by SW2 on the indoor unit control PCB. Unit No. setting by SW2 is necessary for the indoor unit only. In cases of the twin and
triple specification, it is necessary set for the master and the slave units. This can be selected by SW5. (All are set for the master unit at the
shipping from factory.)
SW2: For setting of 0 – 9, A – F
SW5: For setting of master and slave units
(See table shown at right.)
(2) Unit No. may be set at random unless duplicated, it should be better to set orderly like 0, 1, 2…, F to avoid mistake.
(b) Display to the remote control
(i) Center or each remote control basis, heating preparation: the youngest unit No. among the operating units in the
remote mode (or the center mode unless the remote mode is available) is displayed.
(ii) Inspection display, filter sign: Any of unit that starts initially is displayed.
(iii) Confirmation of connected units
1)
In case of RC-EX1A remote control
If you touch the buttons in the order of “Menu”
→
“Next”
→
“Service & Maintenance”
→
“IU address” on the
TOP screen of remote control, the indoor units which are connected are displayed.
2)
In case of RC-E5 remote control
Pressing “AIR CON No.” button on the remote control displays the indoor unit address. If “
▲
” “
▼
” button is
pressed at the next, it is displayed orderly starting from the unit of youngest No.
(iv) In case of anomaly
1)
If any anomaly occurs on a unit in a group (a protective function operates), that unit stops with the anomalous
stop but any other normal units continue to run as they are.
2)
Signal wiring procedure
Signal wiring between indoor and outdoor units should be made on each unit same as the normal wiring. For the
group control, lay connect with sires wiring between rooms using terminal blocks (X, Y) of remote control.
Connect the remote control communication wire separately from the power supply wire or wires of other
electric devices (AC220V or higher).
(19) High ceiling control
When sufficient air flow rate cannot be obtained from the indoor unit which is installed at a room with high ceiling, the air flow
rate can be increased by changing the fan tap. To change the fan tap, use the indoor unit function “FAN SPEED SET” on the
wired remote control.
