Pre-Installation
Before installing the AXT-TEMP and RTS1, you must properly set jumpers and
potentiometers (POTs).
Setting Fahrenheit or Celsius
Set the Fahrenheit or Celsius feature by manually selecting each jumper (JP1- JP4) or by manually
selecting the RAW A/D OUTPUT jumper on the card. FIG. 3 shows the location of the jumpers and
POTs. The RAW A/D OUTPUT jumper overrides jumpers JP1 - JP4.

Jumpers JP1 - JP4 and
JP13 (RAW)

Jumpers JP9 - JP12
Setting the Jumpers
Use the two-position jumpers (FIG. 4) to select Fahrenheit or Celsius operation. The setting takes
effect when you power on the system or reinsert the card into the CardFrame. The default setting is
Fahrenheit (°F).

°C
JP1
FIG. 4 Jumpers
1. Set each jumper (JP1 - JP4) on the card for either Fahrenheit or Celsius.
2. Set all calibration POTs to zero. Each POT is a 25 turn POT. Full counter-clockwise is a -4°
variance and full clockwise is a +4° variance.
To access the jumper and POTs, remove the AXC-TEMP card from the CardFrame.
After making all adjustments, be sure to reseat the card properly. You can also adjust
the card using an optional Axcess Extender Card (AXC-EXTN), for easier access.
3. Insert the card into the desired Axcess CardFrame slot. It is not necessary to disconnect power
to the CardFrame when installing the card.

Pre-Installation
4. Hold the card by the tab end and slide the card into the frame. Make sure the card is correctly
positioned in the guide slot.
5. Gently push the card in until it is firmly seated in the card connector slot. It is not necessary to
disconnect the power to the CardFrame when installing the card.
Calibrating POTs
Use the four calibration potentiometers (POTs), marked CH 1 - CH 4, to adjust the respective RTS1
units 1 - 4. The default setting for each POT pointer is 0°. The table below describes the POT
calibration for CH 1 - CH 4.
Calibration POTs CH1 - CH4
POTs Description
R1 Offsets input CHAN1 by -4 to +4 degrees
R8 Offsets input CHAN 2 by -4 to +4 degrees
R2 Offsets input CHAN 3 by -4 to +4 degrees
R9 Offsets input CHAN 4 by -4 to +4 degrees
R33 Stops Adj for input CHAN 1 (for RTS2 only)
R34 Stops Adj for input CHAN 2 (for RTS2 only)
R35 Stops Adj for input CHAN 3 (for RTS2 only)
R36 Stops Adj for input CHAN 4 (for RTS2 only)

Pre-Installation
RTS1 Preparation
To install the RTS1 units:
1. Wire RTS1 units 1 - 4. Refer to Wiring the RTS1 for additional information.
2. Check the temperature.
! If the panel has a display, check the temperature readings on the system Wiring control
panel. The temperature readings will change when the room temperature changes by a
half degree.
! If the panel does not have a display, check the variables in Axcess.
Wiring the RTS1
Use Belden 8723 or equivalent cable. When an application or code requires plenum-rated cable, use
Belden 88723 or equivalent cable.
Call AMX Technical Support for any installations that require a wire run of more than 100 feet.
RTS1 depth is 0.9"

1. Place a reference thermometer near RTS1 unit 1.
2. Allow the reference thermometer to stabilize for approximately 1-minute.
3. Adjust calibration POT R1 (CHAN 1) clockwise or counter-clockwise to match the reference
thermometer temperature.
When connecting wiring, ensure the Drain and Green wires are used. The
capacitance/filtering effects of these wires are required for accurate measurements.
4. Touch the sensor at bottom of RTS1 unit 1 for 2-seconds to force a temperature change.
5. Wait approximately 5 seconds for the temperature to stabilize. Then, recheck the display panel
temperature display. Allow the reference thermometer to stabilize approximately one minute,
then check.
6. If necessary, repeat steps 1 - 5 for RTS1 units 2 - 4, and move the reference thermometer near
each sensor you are calibrating.

Pre-Installation
Testing the RTS1
Touch the sensor at the bottom each RTS1 unit for a few seconds. The temperature on the display
panel should change. If the temperature does not change:
1. Check the wiring to each RTS1 unit that did not display a temperature change.
2. Verify the AXC-TEMP card is properly seated in the CardFrame. Repeat the steps provided in
the RTS1 Calibration section on page 6, if required.

Programming
This section provides the Axcess programming commands for the AXC-TEMP and RTS1.
! The TEMP_LEVEL variable receives data from the TEMP card (Device 16), inputs 1 - 4.
! The data is in three-digit numbers (986 = 98.6 degrees). The SEND_STRING command
to the Mini-LCD Panel converts the number to print with a decimal point.
! The 12 clears the LCD screen.
