Model TZ45R
Z-Wave Thermostat
This thermostat is compatible with most HVAC systems, including the following:
24VAC systems Note: requires both the 24R and 24C (common) wires
Standard gas/oil/electric heating systems
o1 stage heating and cooling
o2 stage heating and cooling
Heat Pump systems:
o1 stage heating and cooling
o2 stage heating and cooling
o2nd or 3rd stage Auxiliary heating (heat strips)
Do NOT use for line voltage controls (120/240VAC)
Stop! Before removing your existing thermostat do the following:
1. Take a picture of the original wires and terminal connections
2. Label the wires with the terminal markings on the old thermostat
3. Record old thermostat terminals and the wire color connected to them below

type in the Installer Settings menu to C/O Type: w/Heat. Otherwise leave it set to
w/Cool.

Thermostat Setup:
Heat Pump HVAC Systems
To set the HVAC system type, go to the Thermostat Info screen
and press Setup button.
1. Type. Set the HVAC System Type: set to Heat Pump
2. Fan Type. Automatically set for heat pump systems. Ignore this setting.
3. C/O type. Change Over (reversing) Valve Type. Heat pumps change from heating to cooling by reversing operation.
You must configure the thermostat’s changeover valve setting to work correctly with your HVAC system.
Check your system information to be sure and note the color of original thermostat wire and the terminal it was connected to.
No matter what the old stat connection was (O or B), connect the wire to the thermostats W2/O terminal.
The setting of the C/O Type will set the correct system operation.
For change over with cool systems (Orange wire, O terminal): set C/O type to w/cool (most common and default setting)
For change over with heat systems (Brown wire, B terminal): set C/O type to w/heat
4. 2nd Stage Heat. Enable second stage heating outputs
If you have a single stage heating system, leave this set to N
If you have a 2 stage heating system, set to Yto enable.
5. Aux Heat (HP). If you have auxiliary heat strips, set this to Y to enable.
6. 2nd Stage Cool. Enable second stage cooling outputs
If you have a single stage cooling system, leave this set to N.
If you have a two stage cooling system, set to Yto enable.

INSTALLATION SETUP
Before operating the system, the HVAC System Type must be setup in
the Installer Settings/System Settings/Mechanical Settings Menu!
Default Settings: The HVAC System Type is default set for a
Gas/Electric system with Gas Heat Fan type. If this matches the HVAC
system the thermostat is connected to, then no further setup is required.
If the HVAC system has Electric heat or is a Heat Pump system, then the
Mechanical Settings must be changed to match. Go to the Installer
Settings Menu to complete the HVAC setup.
Installer Settings Menu
To change the HVAC setup, go to the Installer Settings Menu. This is a hidden menu
and it can be accessed by pressing the main menu button and when the main Menu
Selection screen appears, press and hold the middle two buttons for 5 seconds.

HVAC Setup Settings
Set these settings to match the HVAC system the thermostat is connected to.
Type Selects HVAC type, Gas/Electric or Heat pump (HP)
Options: Gas/Elec or Heat pump Default: Gas/Elec
Fan Type (if Type=Gas/Elec) Selects the heating system Fan type
Options: Gas or Electric (heat) Default: Gas
C/O Type (if Type=HP)Selects the Changeover Valve type for Heat Pump systems
Options: w/Cool or w/Heat Default: w/Cool
For retrofit installations, refer to the existing thermostat connections to help determine
correct C/O type setting. If the original system had an orange wire connected to an “O”
terminal, then it is a “changeover with cool” system. If there is a brown wire connected to
the “B” terminal, then it is a “change over with heat” system. NOTE: if you get cooling
when expect heating (or heating when you expect cooling), change the C/O type to the
other selection.

Other Installer Settings
The Installer Settings Menu includes other HVAC operation settings that can customize the
thermostat for the installation. CAUTION: these settings affect HVAC system operation
and should only be changed by qualified HVAC service technicians.
Installer Settings Menu Items
Display Lock Options: Y or N Default: N
Y = Display LOCKED N = Display UNLOCKED
Allows you to lock or unlock the thermostat buttons. When the buttons are locked, you can
still access the main menu, but you will not be allowed to select any menu options. The
Installer Settings hidden button operation is always operational, allowing you to return to
this screen and turn Display Lock off.
Service Mode
Test Mode Options: Y or N Default: N
Y= Test mode on. Reduces all delays to 10 sec for quicker system testing
N= Test mode off. Normal system delays
CAUTION: in test mode all system safety delays are shorten. Do not operate the
system compressor in test mode. Disconnect Y1 or Y2 outputs if using test mode
on a live system.
