HAI Omnistat RC-100B

Omnistat thermostats feature a sleek, modern case design that blends in with any décor. The large LCD display with "cool blue" LCD backlight shows time, temperature and operational mode.

Features

• Single stage heat pumps with auxiliary heating
• 2 stage heat, 1 stage cool
• Energy Efficient Control of auxiliary heat to save energy (EEC can be turned off if not desired)
• Automatic anticipator
• Use for water source heat pumps, geothermal heat pumps or air to air heat pumps with electric, hot water or other source of auxiliary heat.

The controls are easy to use, with simple raise and lower temperature keys, mode (off, heat, cool, auto) and fan keys (on, auto). The Prog key is used for programming when the thermostat's internal scheduling features are used. The 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.

Omnistat thermostats feature a multi-mode communications interface for connection to many types of home and building automation systems. This interface 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.

Omnistat thermostats will work with any of HAI's Lumina family or Omni family home control systems. When used with an HAI home control system, full control of Omnistat thermostats is available on a Console or Keypad, OmniTouch touchscreens, telephones (with voice response) and over the Internet with HAI Web-Link II. The HAI home control system's advanced programming features add comprehensive energy management capabilities to one or more thermostats. The HAI home control system automatically sets the thermostat's time and displays the outdoor temperature when an outdoor sensor (available in Omni Accessories) has been setup.

All Omnistat thermostats feature advanced logic for superior temperature control, including "anticipation" for maximum comfort. Uses HAI's advanced Energy Efficient Control (EEC) to minimize the use of expensive auxiliary heat.

ENERGY STAR Logo 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.

HAI is an ENERGY STAR® Partner. All Omnistat thermostats meet the Environmental Protection Agency's ENERGY STAR Guidelines for energy efficiency.

Dimensions: 5.5" W x 3.75" H x 1.1" D

This Omnistat has the following features:

• Large "cool blue" LCD backlight that displays time, temperature and mode.
• Selectable Fahrenheit or Celsius display, AM/PM or 24 hour time format
• Outdoor temperature display (when connected to Omni-family controller and using outdoor sensor)
• Simple user controls for: Mode, Fan, Set, Hold, Raise and Lower Temperature.
• Non-volatile program and setting memory: no batteries required for long term, maintenance-free operation.
• Automatic Changeover between heating and cooling modes (can be configured for manual changeover if auto is not desired).
• Adjustable cycle times.
• Adjustable Anticipator
• System Runtime monitor (this week, last week; hours).
• Filter Clean/Replace indicator reminds owner to clean filter to maintain best efficiency and performance. This reminder is based upon the time the fan has run. It indicates "Filt" on the display to suggest changing the filter. This reminder is reset by pressing the Prog key.
• Compatible with systems using 24 volt (20 to 30 V) AC or DC controls.
• 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 by installer.
• Low limit for cool setting is adjustable by installer.
• Advanced Energy Efficient Control (EEC) monitors performance to minimize use of auxiliary heat.
• Adjustable differential between stages.
• Emergency heat mode (in case of heat pump failure).
• Uses transformer common wire.
• Energy Star compliant and UL Listed.

This Omnistat has the following remote control features:

• 4 communications modes, selectable during installation: 2 serial modes for connection to home automation systems, building management systems and personal computers, and 2 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, 1 start bit, 8 data bits, 1 stop bit NRZ. 300 baud data rate. Can communicate continuously without loss of function. Protocol is available from HAI web site. (Serial Mode 2)
• Remote selection between Day and Night settings: a remote signal (12 VDC) 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 (12 VDC) 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 degrees F. (Voltage signal mode 2)
