For more detailed instructions refer to the complete Energy Management Thermostat Installation and Operation Manual. This is located online at HVAC System / Thermostat Overview The RFTSTAT01 connects to the HVAC system’s thermostat connections just like a traditional thermostat. HVAC System Compatibility The RFTSTAT01 is compatible with most heating and cooling systems. There are two types of HVAC systems: Standard (gas/electric) Heat Pump systems Setpoint Status Up/Down Indicator Buttons LEDs Heating (H) On-Screen and Dynamic Cooling (C) Button Setpoints Labels Function Control Buttons The system type is selectable from the Thermostat Installer Screen by using the Function Control Buttons to access Menu > System Settings > Mechanical Settings submenu. Refer to the complete Installation and Operation Manual for detailed explanation. Standard HVAC systems: For Gas heating or Electric heating. 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 RFSTAT01 is embedded with a Z-Wave module for communicating wirelessesly with Z-Wave compatible control systems. WIRING / INSTALLATION The RFTSTAT01 requires 24VAC power from the HVAC system it is controlling. Refer to Figure 1 for connection to a Standard HVAC System and Figure 2 for a Heat Pump HVAC System. • Connect the 24V/AC Common (typically the Blue wire/terminal) from the HVAC system to the thermostat terminal block 24Com • Connect the 24V/AC Return (typically the Red wire/terminal) from the HVAC system to the thermostats HVAC System terminal block 24RH or 24RC terminals NOTE – the 24RH and 24RC terminals are default tied together in the thermostat. Most HVAC systems have a common heating and cooling transformer. 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. Refer to the complete Thermostat Manual for a detailed explanation. NOTE – Do NOT split the 24RC/24RH terminals for a Heat Pump system.

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 heating and W2 for stage 2 heating. Two Stage Cooling systems use Y1 for stage 1 cooling 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. This is typical of most central HVAC systems. 24COM 24RC 24RH W1 HEAT W2/O G FAN Y1 COMP Y2 COMP FIG. 2: HEAT PUMP HVAC SYSTEM WIRING RFTSTAT01 Heat Pump HVAC System JP1: Internal RC/RH Jumper See notes BLUE RED WHITE ORANGE GREEN YELLOW BROWN C 24V/AC COMMON R 24V/AC RETURN W 1 AUX HEAT CHANGE OVER VALUE O or B G FAN Y1 COMPRESSOR STAGE 1 Y2 COMPRESSOR STAGE 2 THERMOSTAT CONNECTION Typical HVAC system thermostat wiring color codes Be sure to verify your systems wiring color codes Figure 2 : Installation Notes – Heat Pump HVAC System Setup System Type: Set the system type to Heat Pump in the Mechanical Settings menu of the Installer Setup. Single Stage Compressor Systems: Use Y1 for stage 1 heating/ cooling, and W1 for stage 2 Aux Heating. Two Stage Compressor Systems: Use Y1 for stage 1 heating/cooling and Y2 for stage 2 heating/cooling and W1 for stage 3 Aux Heating. Change Over Valve: You must configure the thermostat’s changeover valve setting to work correctly with your HVAC system. Check your HVAC system documentation to be sure. • Changeover settings are made in the Installer Settings > System Settings > Mechanical Settings menu. • Changeover with “Cool” is the default setting and typical for most systems. • If you get cooling when you expect heating, change the C/O type to the opposite setting. 24COM 24RC 24RH W1 HEAT W2/O or B G FAN Y1 COMP Y2 COMP Z-Wave INSTALLATION Aspire RF’s controllers (RFHDCSG and RFTDCSG) support the Helios Z-wave Thermostat General Version 2 Device class.
