Thermostat Info

The Thermostat Info screen displays the current configuration of the Z-WAVE Thermostat. This information is useful for quick check of firmware versions and HVAC system setup. It also shows the ZWave network setting.

Thermostat information displayed is:

 Thermostat - Model and firmware version number.  Z-Wave Settings – ZWave Firmware version, ZWave Node ID, ZWave Home ID  System Type - Standard or Heat Pump HVAC system  Fan Type – if HVAC type = Standard: Gas or Elect

 Changeover – if HVAC type = Heat Pump: Changeover with cool or changeover

with heat.

Thermostat Info Screen

Thermostat Operation

Minimum Run Time (MRT)

The thermostat has a Minimum Run Time after the start of any heating or cooling call. This minimum run time assures even heating and cooling cycles. The MRT delay will keep the system on even if reaches setpoint or 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. The MRT can be adjusted in the Installer Settings menu of the thermostat.

Note: The MRT status is shown in the thermostat System Status on-screen labels.

Minimum Off Time (MOT)

The thermostat has a Minimum Off Time after any heating or cooling call is finished. 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 system from restarting. 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: The MOT status is shown in the thermostat System Status on-screen labels.

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, Add or Install 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. When prompted by your Z-Wave controller, 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 Node ID (ZNID) located in the Thermostat Info screen. An un-installed thermostat should show zeros for the Node ID (000). 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 Home mode it was in 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.

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.
