Restriction when the Lossnay units are connected with the central control-
ler transmission cable

When the Lossnay units and the Lossnay remote controllers are connected with the central controller transmission cable, the number of the
Lossnay remote controllers is restricted because of the capacity of the power supply unit.
The following table shows how many Lossnay remote controllers can be used.
The number of the Lossnay units that isn’t supplied power from the cable doesn’t concern about it.

Registering the Lossnay Unit With the Lossnay Remote Controller

(Initial registration mode operation)

A Lossnay unit must be registered with the Lossnay remote controller in a group arrangement. Register a Lossnay unit using the initial registra-
tion mode as shown below. In addition, the initial registration mode can be used to search for a Lossnay unit registered to the group or to delete
a registration.

Setting Procedure

1

Turn off the unit.
(Perform the following operation after “H0” flashes on the display.)

2

Hold down both 

 and 

FILTER

 for more than 2 seconds.

This starts the initial registration mode and the set Lossnay re-
mote controller address flashes on the display.

Ensure that installation work is done correctly following this installa-
tion manual.

Any deficiency caused by installation may result in an electric shock or fire.

All electrical work must be performed by a licensed technician, ac-
cording to local regulations and the instructions given in this manual.

Any lack of electric circuit or any deficiency caused by installation may re-
sult in an electric shock or fire.

Do not move and re-install the PZ-52SF-E yourself.

Any deficiency caused by installation may result in an electric shock or fire.
Ask your distributor or special vendor for moving and installation.

Ask your dealer or technical representative to install the unit.

Any deficiency caused by your own installation may result in an electric
shock or fire.

Install in a place which is strong enough to withstand the weight of
the PZ-52SF-E.

Any lack of strength may cause the PZ-52SF-E to fall down, resulting in
personal injury.

Firmly connect the wiring using the specified cables. Carefully check
that the cables do not exert any force on the terminals.

Improper wiring connections may produce heat and possibly a fire.

Never modify or repair the PZ-52SF-E by yourself.

Any deficiency caused by your modification or repair may result in an elec-
tric shock or fire.
Consult with your dealer about repairs.

 or after the registration is complete to delete the regis-

tration of the Lossnay unit that is currently displayed.

When the display appears as shown above, hold down [ON/
OFF] twice for 2 seconds each time.

If the registration is deleted correctly, “– – ” appears in the
display.
If the registration is not deleted correctly, “88” flashes in the
display. Check that the selected Lossnay unit address and
the wiring are correct.

NOTE:

• Up to 16 Lossnay units can be registered.
• If the registration cannot be completed or deleted correctly, either the set address or the wiring of the Lossnay unit whose

registration you wish to add or delete may be incorrect. Check the wiring and the address that is set.

Do not install in any place exposed to flammable gas leakage.

Flammable gases accumulated around the body of PZ-52SF-E may cause
an explosion.

Do not use in any special environment.

Using in any place exposed to oil (including machine oil), steam and sulfu-
ric gas may deteriorate the performance significantly or give damage to the
component parts.

Wire so that it does not receive any tension.

Tension may cause wire breakage, heating or fire.

Completely seal the wire lead-in port with putty etc.

Any dew, moisture, cockroaches, insects entering the unit may cause an
electric shock or a malfunction.

Do not wash with water.

Doing so may cause an electric shock or a malfunction.

Do not install in any place at a temperature of more than 40°C or less
than 0°C or exposed to direct sunlight.

The Lossnay unit type,
“LC”, is displayed.

 CAUTION

Do not install in any steamy place such a bathroom or kitchen.

Avoid any place where moisture is condensed into dew. Doing so may cause
an electric shock or a malfunction.

Do not install in any place where acidic or alkaline solution or special
spray are often used.

Doing so may cause an electric shock or malfunction.

Use standard wires in compliance with the current capacity.

A failure to this may result in an electric leakage, heating or fire.

Do not touch any PCB (Printed Circuit Board) with your hands or with
tools. Do not allow dust to collect on the PCB.

Doing so may cause fire or an electric shock.

Do not touch any control button with your wet hands.

Doing so may cause an electric shock or a malfunction.

Do not press any control button using a sharp object.

Doing so may cause an electric shock or a malfunction.

Never contact the power supply with the control wiring terminals.

Doing so will certainly cause the controller to catch fire.

Set the Lossnay remote controller address.

Set the Lossnay remote controller address using the rotary switches SW1
and SW2 on the front of the Lossnay remote controller.

Setting range: 101 to 200
Rotary switch SW1 indicates the tens digit and SW2 indicates the ones digit.
In addition, 100 is automatically added to the setting as shown below.

Lossnay remote controller address

101 - 199

200

The address is set to 01 when the Lossnay remote controller is shipped
from the manufacturer.

 CAUTION:

The address must be set if the Lossnay remote controller is used as a part of a multiunit system. Set the address
according to its position in the system. In addition, refer to the Lossnay Adaptor Installation Manual for more
information concerning the setting of the addresses.

(6)

After setting the Lossnay remote controller address, attach the Lossnay remote controller cover.
When attaching the Lossnay remote controller cover, set the top of the cover onto the two top hooks, then push in on the bottom of the
cover until it snaps into place.
If the bottom of the cover is attached first, the top of the cover cannot be attached. Forcefully pushing in the top of the cover to attach
it may break the hooks.

Lossnay remote controller

(2)

Purchase the thin-copper wiring pipe and locknuts and bushings separately.

2. Install the Lossnay remote controller.

(1)

Pull out about 80 mm of cable from the wall and remove the insulation from its end.

(2)

Use putty to seal the cable lead-in hole in order to prevent insects from damaging the wiring and to prevent air from condensing on the
Lossnay remote controller circuit board. If the hole is not sealed well, the Lossnay remote controller circuit board may be damaged.

(3)

Connect the cable to the terminal board in the bottom rear of the Lossnay remote controller unit.

The cable does not have polarity.

When connecting stranded cable, hold down the button on the terminal board while
inserting the cable.

The cable connects to the main terminal board when it is inserted into the bottom
terminal.

When disconnecting the cable, hold down the button while pulling out the cable.

After inserting the cable, slightly tug on it to check that it does not easily disconnect.
If the cable is not securely connected, a short-circuit or malfunction may occur.

(4)

Remove the Lossnay remote controller cover using a standard screwdriver, then attach the Lossnay remote controller unit to the switch
box using the two enclosed cross-recessed pan-head screws. Use a standard screwdriver with a blade that is 4 mm or wider to remove
the cover.

 CAUTION:

• Forcing off the cover using a screwdriver that is less than 4 mm wide may result in damage to the equipment

or injuries.

• Attach the Lossnay remote controller to a level surface. Do not overtighten the screws, otherwise the case

may become deformed or break.
