AXC-TEMP Temperature Control Card and RTS1 Room Temperature Sensor
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.
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).
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.
3.
Insert the card into the desired Axcess CardFrame slot. It is not necessary to disconnect power
to the CardFrame when installing the card.

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.
