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.
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.

Main Menu - User Settings - Filter Service The Filter Service screen will show the accumulated Filter Runtime hours as well as the Service Interval that will be used to trigger a Filter Message. Any type of HVAC operation that causes the HVAC system fan to run will cause the Filter Runtime value to increase. When the Runtime hours equals the Service Interval hours, the Red LED will flash along with a “Filter” message to remind you to replace the filter.
Main Menu - User Settings - Maint Service The Maintenance Service screen will show the accumulated Heat and Cool Runtime hours as well as the Service Interval that will be used to trigger a Maintenance Message. Any HEAT or COOL type of HVAC operation will cause the respective Runtime values to increase. When the combined HEAT and COOL Runtime hours equals the Service Interval hours, the Red LED will flash along with a “Maint” message to remind you your HVAC system may require periodic maintenance.
Main Menu - User Settings - Sensor Calibration The Sensor Calibration screen allows you to change the temperature calibration of the internal temperature sensor. You can change the temperature calibration by +/- 7 degrees. When the Sensor Calibration screen is selected it will show the current temperature calibration (The (75) in the example screen below) and the current number of degrees of offset being applied (1 deg in the example).
Main Menu - User Settings - Backlite/Display The Backlite/Display screen allows you to set the Backlite timeout and contrast. Backlite Timeout: Sets the time from last button press that the backlite will timeout and turn off. The timeout value is adjustable from 0 or 20 to 120 seconds. If set to “0”, the Backlite will always be ON. If set in the range of 20 to 120 seconds, the Backlite will turn OFF after the selected time expires.

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.
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.
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.
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.
