Home Automation RC-2000 manual

1 1 RC-2000 Th ermostat Installation Ins tructions DESCRIPTION The RC-2000 is a precision digital thermostat designed for 24 VAC he ating and cooling systems. The RC-2000 will support the following systems: ¾ Single Stage Heat/Cool Conventional ¾ Two Stage Conventional (2 Stage Heat / 2 Stage Cool) ¾ Heat Pump (2 Stage Heat / 1 S tage Cool) ¾ T[...]

2 2 Location When replacing an ex isting thermostat, install the RC-2000 in the same location. If the existing location doesn' t meet the following criteria, choose a n ew location to mount the RC-2000. When choosing a location for the thermostat: 1. Ensure that the thermostat is mounted 5 feet above the floor and is at least 2 feet from an ou[...]

3 3 Connect each wire to the terminal st rip(s) on the thermostat base per the wiring diagram for your system application - See Figures 4 - 10. Form the thermostat wiring so that the ca ble lies flat between the terminal strip(s) and the center of the base - See Figure 2 . If a remote s y stem or temperature sensor is bein g used with the thermosta[...]

1 1 2 2 REMOTE SYSTEM WIRING DIAGRAMS This thermostat has been prepro grammed with energy saving program schedules in accord ance with the ENERGY STAR ® program. W hen used with a remote system, HAI recommends that the Program Mode be configured as “None” or “Occup ancy”. This will disable the internal program schedules. HAI HOME CONTROL S[...]

1 1 3 3 REMOTE SETBACK SWITCH The thermostat can be connected to a remote switch to toggle the desired heat and cool temperature se ttings between preset setpoints. A signal ca n be sent from the re mote switch location to ch ange the thermostat temperature setting s from the Occupancy Day temperature se ttings to the Occupancy Night temperature se[...]

1 1 4 4 REMOTE TEMPERATURE SENSOR A remote temperature se nsor can be installed to monitor the temperature from a re mote location or can be combined with the onboard temperature sensor for the average temperature of two locations. Run a twisted pair, shielded cable from the RC-20 00 to the remote temperature sensor location. For distances up to 10[...]

1 1 5 5 SETUP AND CONFI GURATION NOTE: For proper operation of the features of this thermostat, the Ti me and Date must be set. Even w hen connected to an HAI controller which sets the time and day, the Date must be manually set in the ther mostat under the “S ettings” menu. INSTALLATION SETTINGS This section describes the items that the instal[...]

1 1 6 6 System Options Note: Before op erating the the rmostat, the “S y stem Type” and “S ystem Mode” must be configured.

Cool Minimum On The number of minutes the thermostat forces the cooling system to remain on before turning off. Raising this number will inc rease the total time the cooling system is on (saving energy), but may a llow t[...]

1 1 8 8 This thermostat is equipped with Energy Efficient Control (EEC) tha t continually monitors the performance of the HVAC system and uses Stage 2 (he at or cool) and Stage 3 (auxiliar y heat) onl y when necessary. If it determines that Sta ge 1 is able to heat or cool at a rate of 5 degrees per hour or better, Stage 2 will not be used. If Stag[...]
