Model TBZ500

Battery Powered Z-Wave Thermostat

This thermostat is compatible with most HVAC systems, including the following:

 24VAC systems Note: requires both the R and C wires unless battery powered.

 Standard gas/oil/electric heating systems

o 1 stage heating and cooling

o 2 stage heating and cooling

 Heat Pump systems:

o 1 stage heating and cooling

o 2 stage heating and cooling

o 2

or 3

stage Auxiliary heating (heat strips)

 Do NOT use for line voltage controls (120/240VAC)

The thermostat can be powered by batteries or 24VAC.

Battery Power

The thermostat can be powered by four AA Alkaline batteries. The thermostat will operate

for approximately two years on four AA Alkaline batteries depending on the frequency of

user operations and backlight operation. Always use Alkaline batteries and replace in

complete all four at a time with new batteries.

Z-Wave Operation when Battery Powered

Important Note: If the thermostat is installed on a Z-Wave network, while it is battery

powered, it will not work as a Z-Wave repeater.

24VAC Power

Powering the thermostat with 24VAC power requires both the C wire (24VAC common

wire - typically blue) and the R wire (24VAC hot wire - typically red). If the C wire is not

available, then batteries are required.

Note! If the thermostat is powered from 24VAC, batteries are not required.

Z-Wave Operation when 24VAC powered

If the thermostat is installed on a Z-Wave network while it is 24VAC powered, it operates

as an always-on Z-Wave repeater.

Installation Steps

 Remove old thermostat.

 Install TBZ500

 Set up the thermostat for the HVAC system

 Enroll on Z-Wave network

Remove old thermostat

 Turn off power. Usually at the heating/cooling system or circuit- breaker panel.

 Remove cover of old thermostat to expose the wiring terminals

 Take a picture of the wiring terminals! Note: This will help with

troubleshooting later if needed.

 Mark the wires attached to the terminals with the wiring labels included

To connect dual transformer systems, FIRST REMOVE THE SUPPLIED RH-RC JUMPER. Then connect the heating “R” wire to the RH terminal and the cooling “R” wire to the RC terminal on the thermostat. Single Stage Heat Pump HVAC System Wiring to the Thermostat Connect the wires as marked from the HVAC system to the corresponding terminals on the thermostat back. *C wire (24VAC common) Heat Pump systems usually have the C wire connected to the thermostat. If there isn’t a C wire, batteries must be installed.

Thermostat Setup The thermostat must be setup for the correct system type and configuration of the HVAC system for proper operation. Preset HVAC System settings The thermostat is preset for the following typical HVAC system configuration:  HVAC system type: Standard gas/electric  HVAC fan type: Gas heat  HVAC heating stages: one  HVAC cooling stages: one If the thermostat is installed on this type HVAC system, the System setup does not need to be changed.

  Press Select to set. Press Done to exit Fan Type (For Standard HVAC systems only) Fan type depends on the heating system type.  For Gas heat: select “GAS”. This is the default setting.  For Electric heat: use the Up/Dn arrows to change to “ELECTRIC”.  Press Select to set  Press Done to exit Changeover Type (For Heat Pump HVAC systems only) The changeover (or reversing) valve is used to change from heating to cooling operation.

To unlock the thermostat, press and hold the FAN button for 5 seconds to access the Setup screen (it’s the only button that works in the lock mode). Access the Advanced Settings Menu (as above) to turn the Display Lock off. Test Mode Range Y or N Default: N Test mode shortens the system built-in delays (like MOT and MRT) Y= Test mode on. Reduces all delays to 10 sec for quicker system testing N= Test mode off.

See Installation Guide for more information on System setup and the Advanced Systems Menu Z-WAVE Menu This menu item allows the thermostat to be enrolled to the Z-Wave network. Follow the instructions shown in the Z-Wave® Operation section (page 19) to enroll the Thermostat onto the network. CLOCK Menu Set the time and day of the week. Press select to set the DAY. The current day of the week setting will be displayed. Press the UP/DN arrows to change the day of the week desired.
PAGE 18
Minimum Off Time (MOT) The thermostat has a Minimum Off Time (MOT) delay after any heating or cooling cycle ends. This delay prevents rapid heating/cooling cycles and also provides “short cycle protection” for the system compressor. This delay may be noticeable when you change a setpoint and it does not respond immediately due to the MOT delay timer preventing the system from restarting.

Z-Wave® Operation Thermostat Battery Operation: If the thermostat is installed in a Z-Wave network while powered by batteries, it will be enrolled as a Z-Wave FLiRs type device. This is a power saving mode that conserves the batteries by keeping the radio asleep most of the time. However, in this mode, the thermostat does not act as a repeater/router in the Z-Wave network.
