READ ALL INSTRUCTIONS

Make sure your installation will conform to all applicable codes and requirements.

INSTALLATION

POWER CONNECTIONS:

WARNING: Make all connections with the power off to avoid injury to the installer or damage to
the device.

The WHITE and BLACK wires are the only required connections for powerline communications.

POWER LINE CONNECTIONS

The GREEN wire connects to the electrical system ground. The BLACK wire connects to the BLACK
(or hot) wire of the electrical system. The WHITE wire connects to the WHITE (or neutral) wire of
the electrical system. It must be a true neutral or the TH104 will not work. The BLUE wire connects
to the switched load. Make sure connections are tight and no bare conductors are exposed.

Leave cover off to enable address programming.

PROGRAMMING

Address Programming: Connect a suitable PCC transmitter such as the AT004 to the same power

line on which the TH104 is connected.

Select the desired letter & number code on the AT004 and press "Transmit" once. Press and hold
the PROGRAM push-button inside the TH104 for just over three seconds and release. The
TH104 STATUS LED should turn ON and remain on. The TH104 is now in PROGRAM mode.

Select the desired letter & number code again on the AT004 and push "Transmit" twice. The
TH104 STATUS LED should blink twice (indicating address setting received) and remain ON,
indicating it is still in program mode. If using a one way receiver, proceed to page 2 and read "Using

one-way receivers".

If a two way A10 receiver is being used, exit the PROGRAM mode by pressing the PROGRAM push­button on the TH104 once.

TH104 Installation Instructions

"Using one-way receivers" with the TH104: The TH104 default setting is to "request status" after
transmitting because it is designed to be used with A10 enhanced receivers having two way
communication. To use with receivers having only one way communication, you must disable the
status request feature as follows.

While still in PROGRAM mode transmit OFF on the AT004 twice. The TH104 STATUS LED will blink
three times indicating "request status" is set to OFF. To exit the PROGRAM mode press the
PROGRAM push-button on the TH104 once and the STATUS LED will go off, or 1 minute after the
last transmitted command it will automatically exit PROGRAM mode. LED indications are as
follows:

STATUS LED Off - TH104 is In RUN mode
STATUS LED On - TH104 In PROGRAM mode
STATUS LED blinks 2 times - Valid Address
STATUS LED blinks 3 times - Valid Command
STATUS LED blinks continuously - Hardware Error. Return for replacement
SLOT LIGHT and HVAC LED blink continuously, the following may be the problem:

1. Jumper J2 which selects Local (L) or Remote (R) sensor may not be correctly placed.

2. Remote sensor (thermistor) may be bad

3. Remote sensor wiring may be open or shorted.

4. Status Request failure. Incorrect status or no status is received.

5. Collision Failure (unable to transmit due to collision with other signals on powerline).

CHECK OPERATION

A typical installation will use an RI104 as a receiver to control the HVAC unit. To verify operation
program an RI104 to the same address as the TH104 and connect both the TH104 and RI104 to
same power line system. Manually turn off relay 1 of the RI104. Apply power to both devices and
insert a room key in to the TH104 slot. If both are operating properly, after a five second delay relay
1 on the RI104 should turn on. Remove the room key from the TH104 and relay 1 on the RI104
receiver will turn off after a 1 minute delay.
