!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
set or change the setpoint.
!To change the Heat Setpoint you must be in the 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.
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.

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.

Remote Sensors
The thermostat has two remote temperature sensor inputs.
Remote Sensor RS1. When connected, the thermostat will use the RS1 remote sensor
instead of the internal sensor. Temperature displayed will be the RS1 temperature.
Remote Sensor RS2. Selectable Indoor or Outdoor Sensor type. RS2 can be selected to
be an indoor remote sensor or an outdoor remote sensor in the Installer Settings Remote
Sensors menu item.
RS2 set to Indoor (default setting). When set to Indoor sensor type, RS2 is an averaging
sensor that is averaged with the internal thermostat temperature sensor. If RS1 is also
attached, RS2 will be averaged with the RS1 sensor instead (since it replaces the internal
sensor).
RS2 set to Outdoor. When set to Outdoor sensor type, RS2 will be used to display
outdoor temperature on the thermostat.

Z-Wave Remote Sensors
Z-Wave remote sensors can also be used for remote thermostat sensors. When Z-Wave
remote sensors are installed on the same Z-Wave network as the thermostat, their node
IDs can be linked to the thermostat as either RS1 or RS2 remote sensors. Note: Do not
attach both hardwired remote sensors and Z-Wave remote sensors at the same time.
In the Installer Settings Remote Sensor menu, set the Z-Wave network node ID for the Z-
Wave remote sensor that is to be used for either the RS1 or RS2 remote sensor. The
thermostat will use the Z-Wave remote sensor temperatures the same as if it was
hardwired to the RS1 or RS2 terminals. The function of the thermostat with a Z-Wave
remote sensor is identical to the RS1/RS2 usage shown above.

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.
