MODEL CA8900 Z-Wave®  
Digital Thermostat  
Installation and User Instructions  
Description and Features  
The CA8900 is a digital thermostat that can be con-  
trolled wirelessly with Z-Wave controllers supporting  
the Thermostat General V2 Device Class. The thermo-  
stat is compatible with all standard 24 VAC heating  
and cooling systems, up to two-stage heat, one-stage  
cool, and two-stage heat pump. The CA8900 operates  
as a simple thermostat with buttons to set target tem-  
peratures for heat and cool modes. The Save Energy  
button adds two more modes for target temperatures  
to provide a single button set-back mode for easy op-  
eration. It can easily be retrofitted to existing systems  
as part of a Z-wave control strategy.  
The CA8900 Wireless Thermostat provides two-way  
communication as part of a Z-Wave® network. When  
it receives commands from the Central Controller  
Unit, it sends back confirmation that the command  
was received and imple-  
• This thermostat can be used with all 24VAC heat-  
ing and cooling systems. It cannot be used with line  
voltage systems.  
• The CA8900 is digital and your desired heat or cool  
temperatures can easily be set on the large screen  
with the TEMP UP (+) and TEMP DOWN (-) buttons  
on the front.  
mented. Each module in a  
Z-Wave network communi-  
cates with every other mod-  
ule, acting as a “repeater”  
• A minimum 4-minute off time protects heating and  
cooling systems from damage.  
• This thermostat uses a new technique called sequen-  
tial staging for more comfort with faster reaction to  
requested temperature changes.  
and routing your commands  
to their destination by the most reliable pathway.  
When Z-Wave devices (regardless of manufacturer)  
are installed throughout the house, signals are au-  
tomatically routed around obstacles or dead spots,  
strengthening the network as more devices are added.  
The Z-Wave icon shows on the lower right of the dis-  
play panel, indicating that the thermostat is in contact  
with the controller. If the icon is not present, commu-  
nication has been lost. If this occurs, all remote HVAC  
functions are shut off.  
NOTE: When using a heat pump with auxiliary  
heat, if the heat pump cannot keep up and/or is  
defective, remove jumper from position 2B and put  
jumper on position 2A. This will make the auxiliary  
heat your only source of heat. Be sure to restore it  
to PUMP when the pump is again operational, as  
auxiliary heat is more expensive than pump heat.

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  
AA batteries 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.  
Fahrenheit / Celsius  
Indicator  
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).

WARNING–Risk of Fire or Electric Shock  
• To avoid fire, shock, or death, and to prevent damage to the furnace,  
air conditioner, and thermostat, disconnect the power supply before  
beginning work. This can be done at the circuit breaker, or at the  
appliance.  
• Do not short (jumper) across electric terminals at control on  
furnace or air conditioner to test the system. This will damage the  
thermostat and void your warranty.  
• All wiring must conform to local codes and ordinances.  
• Your thermostat is a precise instrument, handle it with care.  
• Do not turn electricity back on until work is completed.  
• This thermostat is designed for use with 24 volt AC systems. The  
thermostat should be limited to a maximum of 1.0 amps; higher  
amperage may cause damage to the thermostat.

2. Attach labels (enclosed) to each wire for identifica-  
tion.  
2 – Label Wires from Old Unit  
IMPORTANT : LABEL ALL  
WIRES BEFORE DISCONNECT-  
ING THEM!  
NOTE: Read instructions carefully before remov-  
ing any wiring from existing thermostat. Wires  
must be labeled before they are removed. THERE  
IS NO STANDARD COLOR CODE. When remov-  
ing wires from their terminals, ignore the color of  
the wires since these may not comply with any  
standard.  
Switch electricity to the furnace  
and air conditioner OFF; then  
proceed with the following steps.  
1. Remove cover from old thermostat. Most are snap-  
on types and simply pull off. Some have locking  
screws on the side or front. These must be loos-  
ened. Note the letters printed near the terminals.  
NOTE: Make sure the wires do not fall back in-  
side the wall. You can wind them around a pencil  
to keep them from falling.  
3 – Remove Old Unit  
1. Label the wires one at a time. You must label all the  
wires before you proceed.  
3. Loosen all screws on the old thermostat and re-  
move it from the wall.  
2. With all wires labeled, remove them from the old  
unit.  
4. Fill wall opening with non-combustible insulation  
to prevent drafts.

Before You Connect Wires  
Please follow these guidelines for safe and secure wire  
connections.  
Which wires do you have?  
• Use the Step-By-Step diagram as  
your guide.  
• Determine which step-by-step wiring diagram you  
should use from the next pages. Make sure your  
wires are labeled. This may require you to find the  
‘other end’ connection for each wire on your heat-  
ing or air conditioning equipment and read the label  
there.  
• Strip 3/8” of the wire and form as  
shown  
• Take care not to damage the labels for each wire in  
handling.  
• You must have a wire marked “C” (24VAC) for the  
CA8900 to operate. Without the 24VAC power, the  
CA8900 will run on its back-up batteries for just a  
few days.  
• Fan wires out as illustrated with CA8900 below the  
wall opening.  
• Wires will dress behind the CA8900 and up over the  
terminal area.  
• Do not bunch wires behind CA8900. Feed slack  
back into the wall opening.  
• Connect labeled wires only to a terminal with cor-  
responding letter.  
CAUTION: Do not allow wires to touch each other  
or parts on thermostat.  
• Insert the wire in the terminal and tighten the screw  
securely.  
• You will need to
