Joining to a Z-Wave®Network

To join a Z-Wave network, set the Z-Wave controller to INCLUDE mode, then press and release the BIND button on the CA8900 thermostat. Follow instructions provided with your controller. You would also use the BIND button when excluding from a Z-Wave network.

Low Battery Warning

When the batteries are low, the battery icon on the display panel will flash. The two

AAbatteries in the unit need to be replaced. These batteries are not for operation, but provide battery backup for your settings. The thermostat requires 24VAC for operation, and

the HVAC system will stop function if the thermostat loses power.

Replace the batteries as soon as you see the flashing battery icon. Press the RESET button after replacing batteries.

Displaying Fahrenheit or Celsius

Whether the temperature display panel displays in Fahrenheit or Celsius depends on the position of the F/C jumper. The F/C jumper is at the top right of the PCB, called Jumper 4 in the diagram below.

With the jumper removed, the display is in Fahren- heit (the default setting).

With the jumper placed on both pins, the display is in Celsius (centigrade).

When the jumper is changed, you must press the RESET button on the front of the thermostat.

Setting a Heat Pump’s AUX ONLY Mode

If you have a heat pump with auxiliary heat and the heat pump is not working or cannot keep up with heat demand, you can use the auxiliary heat only.

Move the jumper from position 2B [heat pump] to position 2A [Aux only].
