INSTALLATION MANUAL FOR PC-P2HTE
1. SAFETY SUMMARY
DANGER:
-DO NOT pour water into the remote controller
(hereafter called “controller”). These products are
equipped with electrical parts. If poured, it will cause a
serious electrical shock.
-DO NOT operate switches by wet hand. It may cause
an electrical shock.
-In case that the protective devices often function or
the operation switches do not function well, turn OFF
the main power supply and contact your service
contractor of HITACHI.
-In case that other abnormalities are found, stop the
system, turn OFF the main power supply and contact
your service contractor of HITACHI.
WARNING:
-DO NOT perform installation work and electrical wiring
connection by yourself.
In case that a service work such as repair,
maintenance, etc. is required, contact your service
contractor of HITACHI.
-DO NOT modify the electrical wiring. It may cause
serious accidents.
2. INSTALLATION WORK
2.1. SELECTION OF INSTALLATION PLACE
Location of Remote Controller
Select a suitable place for handling and determine the
installation place of the controller with the customer’s
acceptance.
Especially in case that a remote control thermistor (C8)
is used, pay attention to select the installation place.
NOTE:
For one remote controller, the maximum total length
of the cable (including the signal wire between units)
is 30 m when using 0.3 mm² cable and 500 m when
using the cable thicker than 0.75 mm².
2.2. BEFORE INSTALLATION

2.3. INSTALLATION SPACE
In case of installing the controllers in vertical line, keep a
distance more than 50 mm between the controllers
vertically. If the distance is insufficient, the front cover of
the controller can not open wide enough
2.4. INSTALLATION PROCEDURE
1. Insert the edge of the flat head screwdriver into the dent parts at the bottom of the holding bracket, push and turn the
screwdriver and remove the controller from the holding bracket as shown in the next figure.

In case of exposing Remote Control Cable.
1. Fix the holding bracket onto the wall as shown
below
2. Attach the stopper to the cable at the inside of the
draw-out hole.
3. Lead the cable with its sheath peeled through the
groove
4. Peel the insulation at the end of the cable and clamp
the M3 solderless terminals
When Using Switch Box.
.Run the cable into Field-Supplied JIS Box (JIS 8336 -
1998)
The following 5 types are available.
1. Switch Box for 1 Controller (without
Cover)
2. Switch Box for 2 Controllers (without
Cover)
3. Switch Box for 1 Controller (with Cover)
4. Switch Box for 2 Controllers (with Cover)
5. Outlet Box (with Cover)
Run the cable through the conduit tube in
the wall.
.Fix the holding bracket to the switch box
.Peel the insulation at the end of the cable and clamp
the M3 solderless terminals

.Mounting procedures.
1. Insert the hooks of the controller to the
holes on the top of the holding bracket.
2. Push the lower part toward the holding
bracket.
3. When the click sound is heard, the
controller is attached to the holding
bracket and the mounting work is
finished.
CAUTION:
Pay attention so that the cable may not be slack. If
the cable is slack as shown in the above figure, the
cable cord (especially the naked part) may be
clamped at the hole and it may cause a faulty
operation.
3. ELECTRICAL WIRING
3.1. STANDARD WIRING
ATTENTION:
-Attach the ring core (black) (accessory) when
installing the unit.
-Insert the controller cable into the ring core 2 turns as
shown in the right figure before connecting to the
terminal board.
If wiring is 0.75 mm2is necessary to peel the outside
cover.
-Fix the cable by using the band (accessory)

INSTALATION AND OPERATION MANUAL FOR PC-P2HTE 3
CAUTION:
-Use the twist (shield) pair cable (2 x 0.75mm²) as
transmitting wire cable for prevention of the
malfunction (The total cable length is max. 500m).
When the total cable length is within 30m, other type
cable (more than 0.3mm²) can be used.
-Keep a distance more than 30 cm between the remote
control cable and the transmission wire of Indoor
units.
-In the case that multiple indoor units are controlled
simultaneously, set the refrigerant cycle number and
the address of Indoor units as indicated below.
Address of Indoor Units:
Main unit 1st unit 2nd unit 3rd unit
4th unit 5th unit 6th unit 7th unit
8th unit 9th unit 10th unit 11th unit
12th unit 13th unit 14th unit 15th unit
4. CHECKING PROCEDURES
1. Turn ON the power supply for all the indoor units.
2. Set the “TEST RUN” mode by pressing the “MODE” and
“OK” switch simultaneously for more than 3 seconds.
ATTENTION:
In case of the control by using two Remote controllers
(Main & Sub), the test running shall be operated by
the main controller.
NOTE:
-The completion of the automatic address setting requires
3 to 5 minutes after turning ON the power supply.
-The total number of the connected units is indicated on
the liquid crystal display.
-In case that the indicated number is not correct, some
abnormalities exist, incorrect wiring, the electric noise,
etc.
-Turn OFF the power supply and correct the wiring after
checking the following points; (Do not repeat turning ON
and OFF within 10 seconds.)
-Power Supply for Indoor Unit is Not Turned ON or
Incorrect Wiring.
-Incorrect Connection of Connecting Cable between
Indoor Units or Incorrect Connection of Controller Cable
-Incorrect Setting of Rotary Switch (The setting is
overlapped.) on the Indoor Units PCB
-Check to ensure that the “Test Run” mode is not set.
3. Canceling “Test Run” Mode
-When the unit is not operating, press the RESET switch.
-When the unit is operating, press the RUN/STOP switch.
CAUTION:
The setting of the indoor unit number can not be
performed by the controller.
In case of setting the unit number, refer to the item
“Address of Indoor Unit” of Item 2 “Electrical Wiring for
multiple units” and perform the setting.
