- Fully interactive with the Omni family of home automation controllers
- Create separate weekday, Saturday and Sunday heating schedules
Essential Info
Get complete control of your home's temperature both locally and remotely with the RC Series family of electronic communicating thermostats! Available for conventional single stage heat/cool, heat pump, two-speed heat pump, two-stage conventional, and zone control systems, the RC Series Thermostats come in a sleek, contemporary case design that blends with any home décor. Use this backlit model for single-stage heating and cooling systems with zoned damper control systems (1-stage cool, 1-stage heat with B and O terminals for master control).

More Info

A large LCD display shows time, temperature and operational mode. The controls are easy to use, with simple raise and lower temperature keys, mode (off, heat, cool, auto) and fan keys (on, auto). A "Prog" key is used for programming when the thermostat's internal scheduling features are used. A "Hold" key maintains the current settings as long as the hold indicator is on. A "remote" indicator shows when the thermostat has been set by remote control.
The thermostats feature a multi-mode communications interface for connection to many types of home and building automation systems. This allows more comprehensive energy and comfort management by setting the thermostats based on occupancy and home or building modes along with traditional scheduling. Two full communications modes are available for connection to automation systems and personal computers. Two additional modes are available for simplified connection to most access control, security and time clock systems.
When used with the OmniLT or OmniPro II, full control of RC-Series thermostats is available on remote LCD consoles, telephones (with voice response) and over the Internet with HAI Web-Link II. The Omni's advanced programming features add comprehensive energy management capabilities to one or more thermostats. The Omni automatically sets the thermostat's time and outdoor temperature displays.
All models feature advanced logic for superior temperature control, including "anticipation" for maximum comfort. Models with more than one stage feature HAI's advanced Energy Efficient Control (EEC) to minimize the use of expensive auxiliary heat. The installer can set limits on the heat and cool settings, to prevent the thermostat from being set too high or too low. The thermostat prevents short cycling, protecting the system's compressor. A filter reminder tracks running time of the fan, indicating when it is time to replace the filter.
All RC Series programmable thermostats meet the Environmental Protection Agency's ENERGY STAR Guidelines for energy efficiency.
Features:
- Automatic Changeover between heating and cooling modes (can be configured for manual changeover if auto is not desired)
- Adjustable cycle times
- Adjustable anticipation for wide range of heating system types, including gas, oil or electric, forced air, radiant, hydronic, steam, etc.
- System Runtime monitor (this week, last week; hours)
- Filter Clean/Replace indicator reminds owner to clean filter to maintain best efficiency and performance (press "Prog" key to reset)
- 5-1-1 programming capability: Separate schedules for Weekdays, Saturday and Sunday, with separate heat and cool settings for morning, day, evening and night. Internal scheduler can be disabled for use with automation systems
- High limit for heat setting is adjustable
- Low limit for cool setting is adjustable
- Non-volatile program and setting memory: no batteries required for long term, maintenance-free operation
- Heat pump and two-stage models have adjustable differential between stages
- Heat pump models have "emergency heat" mode (in case of heat pump failure)
- Uses a transformer common wire to disable power stealing
Remote Communications:
- Four communications modes, selectable during installation: two serial modes for connection to home automation systems, building management systems and personal computers, and two voltage signal modes for connection to time clocks, remote setback switches and many burglar alarm panels.
- Data signal is electrically isolated from heating and cooling system for superior reliability in all modes. Fully interactive with all HAI-manufactured controllers, including mode, heat setting, cool setting, fan and hold settings. (Serial Mode 1)
- Can communicate directly with the RS-232 port of a personal computer — no adapter required. Serial mode protocol: addressable up to 127 units, bi-directional, one start bit, eight data bits, one stop bit NRZ. 300-baud data rate. Can communicate continuously without loss of function. (Serial Mode 2)
- Remote selection between Day and Night settings: a remote signal (12VDC) selects between user programmed "day" and "night" settings for both heating and cooling modes. The settings can be changed by a user, but they will return to the preprogrammed ones on application (for night) or removal (for day) of the signal. Ideal for use with time clocks, building management systems, access control systems, alarm systems to set to preprogrammed temperatures when building is unoccupied. (Voltage signal mode 1)
- Thermostat Override: a remote signal (12VDC) overrides the thermostat operation and turns off the HVAC system. Removal of signal restores normal operation. Remote indicator shows that thermostat is overridden. Safety feature will turn on heat if temperature drops below 45°F. (Voltage signal mode 2)
