TH104 Installation Instructions
P/D 061208
TEMPERATURE SENSORS
Control reverts to the TH104 temperature sensor only when the room key is removed. The TH104
then enables the HVAC if the room temperature falls to 60 degrees F (if HVAC unit is in heating
mode) or greater than 80 degrees F (if HVAC is in cooling mode), using internal or remote sensor.
The remote sensors are useful in multi-room suites were one room may get warmer or cooler than
the other. The TH104 is designed to accept any 10K curve F thermistor. Remote sensors are not
supplied with the TH104 and must be purchased by the installer if required.
The TH104 has two external sensor inputs and can be configured four different ways. Sensor 1 can
be selected for remote or local operation with Jumper Block J2.
1. Local Sensor only, J2 set to L (typical application, factory default)
2. One Remote Sensor only, J2 set to R (remote sensor wired to Sensor 1 terminal).
3. Local Sensor and One Remote Sensor, J2 set to L (remote sensor wired to Sensor 2 terminal).
4. Both Remote Sensors Only, J2 set to R (Remote sensors wired to Sensor terminals 1 and 2).
CHANGING ROOM KEY SIZES
The TH104 can accept two room key sizes. It is factory set to accept the large key card. To accept
the small key card, two snap in pegs on the printed circuit board must be removed from "Lg" and
"Move for Sm" hole positions & moved to both "Sm" hole positions.
LED INDICATOR LIGHTS
The three LEDs on the TH104 indicate following:
1. HVAC Enabled LED: With "Status Request" mode on, and key inserted, the TH104 transmits
ON and STATUS REQUEST after a 5 second delay, and the status LED lights and receiver
responds with a "STATUS ON".
With key removed the TH104 transmits OFF after a 1 minute delay, and the LED and receiver
turn off and receiver responds with a "STATUS OFF".
With "Status Request" mode off, and key inserted, the TH104 transmits ON after a 5 second
delay; the status LED lights and receiver comes on after completion of the signal transmission.
With key removed, TH104 transmits OFF after a one minute delay, LED and receiver goes off
upon completion of the signal transmission.
2. Status LED: Status LED is on only in the program mode and blinks after receiving a valid address
or configuration command. Status LED is off in the run mode.
3. Slot light LED: LED is on to illuminate key card slot. In case of error condition the Slot Light
LED will blink in unison with the HVAC Enabled LED (see below). If Slot Light LED and HVAC
Enabled LED are both blinking, any of the following may be the cause:
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 through other signals on the powerline).
