"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.
