DCN: 141-01773-01 10/20/10 4 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 Status Indicator LEDs Setpoint Up/Down Buttons Function Control Buttons Heating (H) And Cooling (C) Setpoints On-screen dynamic button labels
DCN: 141-01773-01 10/20/10 5 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 TZ45 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.

DCN: 141-01773-01 10/20/10 27 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.
DCN: 141-01773-01 10/20/10 28 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.
DCN: 141-01773-01 10/20/10 29 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 (O/B terminal) Most heat pump systems are designed to work normally in the heating mode and require a change over output for cooling operation. There are two types, O and B. Change the C/O Type in the Installer Settings – System Settings – Mechanical Settings menu option to match your system type. O: Changeover with Cooling (orange wire from HVAC system): Set C/O Type to w/Cool (This is the default setting). B: Changeover with Heating (brown wire from HVAC system): Set C/O Type to w/Heat. Note: during Heat Pump operation, the changeover relay, once engaged, will stay on until an opposite heat or cool 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.
DCN: 141-01773-01 10/20/10 30 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! Remote Sensors The TZ45 is compatible with Model RTS3 and RTS4 two wire remote sensors. Refer to the wiring instructions included with the remote sensor. NOTE: Remote Sensors require shielded twisted pair cable. Connect the shield to the 24VAC Com connector on the wiring terminal strip.
DCN: 141-01773-01 10/20/10 31 HVAC SYSTEM CONNECTION Standard Gas/Electric HVAC System Wiring Installation Notes Standard HVAC System Setup You must set up the system configuration in the Installers Settings – Mechanical Settings Menu (page 23). System Type: Set the system type to Gas/Elec. This is the default setting. Fan Type: Set Fan Type to Gas for gas systems or Elec for electric heating systems. Default is Gas 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. (You must enable two stage heating in installer settings) Two Stage Cooling systems use Y1 for stage 1 and Y2 for stage 2 cooling. (You must enable two stage cooling in the installer settings) 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. JP1: internal RC/RH Jumper on the circuit board. Cut for separate heating & cooling transformer systems.
