Overview
Z-Wave Thermostat
The Z-Wave thermostat provides for typical thermostat control of a central heating and cooling HVAC system plus has the added feature of Z-Wave communications for remote control.
The thermostat has a large, backlit graphical display, control buttons, status LEDs and a temperature sensor. The thermostat can display multiple screens for different functions of the thermostat. The default thermostat control screen shown below, will display the current room temperature, heating and cooling setpoints, system mode, manual-fan mode, time, and status information.
Display operation
Thermostat control screen
Normally the thermostat displays the thermostat control screen as shown above. Using the “Menu” button, you can access other screens and functions of the thermostat.
Minimized Display Mode
Optionally, you can set the thermostat to show only the temperature in a “minimized” display mode. This mode can be set on or off in the thermostat “Users Settings” menu.
Backlight
The thermostat has a backlit display for low light and night visibility. It can be set to remain on constantly, or to turn off after a 20-120 second delay. These are selectable in the User Settings menu.
Status LEDs
The thermostat has four LED’s that displays status information. The LEDs have dynamic “on-screen” labels that change with the screen being displayed.
Function Control Buttons
The thermostats buttons are “Soft Keys” meaning that they change functions when you change screens. The function of the button is defined by “on-screen labels” that are dynamic and change when you change screens

Z-Wave® Installation
Z-Wave controllers from various manufacturers may support the Z-Wave Thermostat General V2 Device class used by the RCS Z-WAVE Thermostat. The following procedure will allow the thermostat to be added to a Z-Wave network.
General Programming Procedure
(for controllers supporting the thermostat device class):
1. Set your primary controller to Include mode, to add the thermostat as a node on your network (see your controller’s user manual for detailed instructions).
2. In the Thermostat’s Main Menu, scroll down to the ZWave Install item. Select the item.
3. Press the YES button in the ZWave Install screen.
Your controller will indicate the thermostat was successfully added to its network (see your controller’s user manual for details). Also you can check if the thermostat was successfully added to the network by checking the ZHID (Home ID) and ZNID (Node ID) located in the Thermostat Info screen.
For other specific tasks such as adding the thermostat to Scenes or Groups, or deleting the thermostat from an existing network, use the Z-Wave Install procedure.
Note: Before adding the thermostat to a Z-Wave Network, check that it does not already belong to one by viewing the Home and Zone ID’s located in the Thermostat Info screen. An un-configured thermostat should show zeros for both the Home and Zone IDs. Consult your controller’s user manual for details on removing a device from a Z-Wave network.
Setback Mode Operation
If your controller does not support full thermostat device class functions, it may still be able to control the energy saving AWAY mode of the thermostat through BASIC_SET commands.
Sending the BASIC_SET (Value = 0x00), the thermostat will go into the AWAY mode and use the predefined AWAY setback setpoints. These setpoints are set in the Main Menu Away Setpoints item.
Sending the BASIC_SET (Value = 0xFF), the thermostat will revert back to the mode it was in (Hold or Run) before the BASIC_SET (Value = 0x00) command was sent.
Note that when the BASIC_SET commands are sent, the TZ43 will momentarily display the new mode on the Schedule Mode screen.
Inclusion and Exclusion
Inclusion or exclusion is started by putting the controller into add node or remove node state and performing the General Programming Procedure outlined above. As part of the process, the thermostat sends a node information frame at normal power.
Low power inclusion or low power exclusion is not possible.

Setting Heating or Cooling Setpoints
Setpoint Up and Down Buttons
Press either the Up or Down button in the main Thermostat Control Screen to go to the current system operating mode (Heating or Cooling) Setpoint screen. as shown below.
Heating /Cooling Setpoint Adjustment Screen
The UP and DOWN buttons adjust the setpoint temperature. Pressing the UP button will increment the setpoint value by one degree and conversely, pressing the Down button will decrement the setpoint one degree. Pressing and holding a button will cause the setpoint to continuously change until the button is released.
Setpoint Range: The setpoints can be set from 50°F to 90°F (4°C to 32°C) for heating or 55°F to 99°F (10°C to 37°C) for cooling.
Setpoint Push: Note that you cannot lower the cooling setpoint below the heating setpoint. The thermostat will “push” the heating setpoint lower if you try to lower the cooling setpoint below the heating setpoint. It maintains a 3 degree separation between the heating and cooling setpoint. The same is true for raising the heating setpoint above the cooling setpoint. Again the thermostat will “push” the cooling setpoint up to maintain the 3 degree separation.
NOTE: If the system mode is OFF, pressing either the Up or Down buttons will take you to the System Mode screen. You must first set an operating mode before you can change the setpoints.
To change the Heat Setpoint you must be in Heating mode, to change the Cool Setpoint you must be in the Cooling mode. If you are in Auto mode, the mode of the last system call will be the setpoint screen displayed.

HVAC System Connection
The thermostat connects to the HVAC system’s thermostat connections just like a traditional thermostat does.
HVAC System Compatibility
The thermostat is compatible with most heating and cooling systems. There are two types of HVAC systems: Standard (gas/electric) and Heat Pump systems. The system type is selectable from the Installer Screen – System Settings – Mechanical Settings submenu.
For Standard HVAC systems: Gas heating or Electric heating. For Heat Pump HVAC systems: supports changeover valve operation for either changeover with cooling
or changeover with heating. Multi-Stage HVAC Compatibility For Standard HVAC systems, the HVAC outputs support 2 stages of heating and 2 stages of cooling. For Heat Pump HVAC systems, the HVAC outputs support 3 stages of heating (2 compressor/1 Aux Heat)
and 2 stages of cooling.
Remote Communications
The Z-Wave thermostats have a Z-Wave communications module for communicating to control systems with Z-Wave capability.

HVAC System Operation and Setup
General Heating and Cooling Operation
In the HEATING mode, the heating system will be turned on at one degree below the setpoint and will turn off at the setpoint. This turn on and turn off offset is referred to as the heating setpoint “delta T” and is adjustable in the Installer Settings menu of the THERMOSTAT. It is set to the one degree operation by default.
In the COOLING mode, the cooling system will be turned on at one degree above the setpoint and will turn off at the setpoint. Similarly, the cooling setpoint delta T is adjustable in the Installer Settings menu.
In the AUTO mode, the system will switch between heating and cooling as determined by the heating and cooling setpoints and the current temperature. Once in a heating or cooling mode of operation, the normal one degree setpoint control is maintained.
Setpoint Push. Heating and cooling setpoints are forced to maintain a separation between them, with a default setting of 3 degrees. If the heating or cooling setpoint is changed to be within the setpoint delta, the system will automatically “push” the other setpoint to maintain the setpoint delta separation. The H/C setpoint delta is also adjustable in the Installer Settings menu of the THERMOSTAT.
Standard HVAC System Types
Gas or electric heating systems are considered “Standard” HVAC systems. These systems consist of an indoor furnace/blower assembly and an outdoor AC condensing unit (for those systems with air conditioning installed). These systems in general are referred to as central forced air HVAC systems.
You must configure the Thermostat to match your HVAC system type for correct system operation.
Setup Standard System Type Selection
To configure the Thermostat for standard Gas/Electric HVAC system operation, change the Type in the Installer Settings – System Settings – Mechanical Settings menu option to Gas/Elec.
Fan Type Selection
Gas systems do not require a fan output for heating operation. Set the Fan Type in the Installer Settings – System Settings – Mechanical Settings – Fan Type to GAS.
Electric (and hydronic) heating systems do require a fan output with the call for heating. Set the Fan Type in the Installer Settings – System Settings – Mechanical Settings – Fan Type to ELEC.
Be sure to check your HVAC system’s requirements.
Heat Pump HVAC System Types
Heat Pump HVAC systems are combined heating and cooling systems. The system consists of an indoor “air handler” (a blower fan and coil assembly) and an outdoor unit. Heat pumps change from heating mode to cooling mode by switching the refrigerant flow using a “changeover” or “reversing valve”. In both heating and cooling operation the compressor and fan outputs are on and the state of the changeover output determines if heating or cooling is being provided. Heat pumps can have one or two stages of compressor operation plus an optional third stage of electric heat strips.
The third stage of heating will be turned on when the current temperature falls 3 deg below the current setpoint and will turn off at the setpoint.

Setup
Heat Pump System Type Selection
To set the Thermostat for Heat Pump HVAC operation, change the Type in the Installer Settings – System Settings – Mechanical Settings menu option to Heat Pump.
Changeover Type Selection
Most heat pump systems are designed to work normally in the heating mode and require a change over output for cooling output. Change the C/O Type in the Installer Settings – System Settings – Mechanical Settings menu option to match your system needs.
Changeover with Cooling: Set C/O Type to w/Cool (This is the default setting). Changeover with Heating: Set C/O Type to w/Heat.
Note: during Heat Pump operation the changeover relay, once engaged, will stay on until the opposite HVAC call occurs.
Check your HVAC system requirements for correct settings.
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time after the start of any heat or cool call. This minimum run time assures even heating and cooling cycles. Minimum Run Time will keep the system on even if you change the setpoint to a temperature that would satisfy the call, until the MRT expires. Changing the Mode to OFF will cancel the MRT and the system will turn off immediately. MRT can be adjusted in the Installer Settings Menu of the THERMOSTAT.
Note: MRT status is shown in the thermostat System Status LED on-screen label.
Minimum Off Time (MOT)
The thermostat has a Minimum Off Time after any heat or cool call. This delay prevents rapid heating/cooling cycles and also provides “short cycle protection” for compressor calls. This delay may be noticeable when you change a setpoint and it does not respond immediately due to another call that has recently completed and the MOT delay timer is preventing the restart of the system. The MOT delay time can be adjusted in the Installer Settings Menu of the THERMOSTAT. There is a minimum of 5 minutes delay to assure compressor protection.
Note: MOT status is shown in the thermostat System Status LED on-screen label.

INSTALLATION
Power
The thermostat requires 24VAC power from the HVAC system it is controlling. Connect the 24VAC Common (typically the Blue wire/terminal) and 24VAC R (typically the Red wire/terminal) from the HVAC system to the thermostats HVAC System terminal block 24VCom and 24V RH or 24V RC terminals (the RH and RC terminals are default tied together)
Common or Split Transformer Systems
Most HVAC systems have a common heating and cooling transformer. A trace is connected to tie the RH and RC inputs together for this configuration. If you have a system with separate heating and cooling transformers, you will need to split the RH and RC jumper by cutting the trace on the PCB.
When wiring split systems, wire the heating systems 24VAC R (red wire) to the thermostat’s RH terminal, and wire the cooling systems 24VAC R to the thermostat’s RC terminal. Also wire the cooling systems 24VAC Com to the thermostat’s 24VAC Com terminals.
Note: Do not split RC/RH for Heat Pump systems!

Standard Gas/Electric HVAC System Wiring
Installation Notes Standard HVAC System Setup
System Type: Set the system type to Gas/Elect in the Mechanical Settings menu of the Installer
Setup. This is the default setting.
Single Stage systems use W1 for heating stage 1 and Y1 for cooling stage 1. Two Stage Heating systems use W1 for stage 1 and W2 for stage 2 heating. Two Stage Cooling systems use Y1 for stage 1 and Y2 for stage 2 cooling. HVAC system transformer: If you have an integrated heating and cooling system with a single
transformer, do NOT cut jumper JP1. Wire the HVAC system’s 24VAC common (blue wire) to the 24Com terminal and the 24VAC Return (red) wire to either 24RH or 24RC terminal. This is typical of most central systems.
If you have separate heating and cooling systems with separate transformers, cut jumper JP1. Wire the heating 24V R (red) wire to the thermostat’s 24RH terminal. Wire the cooling systems 24V R (red) wire to thermostat’s 24RC terminal. Also wire the cooling systems 24VAC Common (blue
wire) to the thermostat’s 24COM terminal.
