Omnistat2 thermostats are the latest generation of programmable communicating thermostats and provide precise digital temperature control over your HVAC system. With the ability to control a host of energy sources including gas, oil, steam, hydronic, forced air, radiant, electric, geothermal, and heat pumps. What makes Omnistat2 thermostats stand above their competition is that they use advanced digital technology to learn the heating/cooling patterns of your home to control the equipment for maximum efficiency and comfort.

Omnistat2 thermostats have an automatic heat/cool changeover, which features an automatic switch from heating to cooling mode and back without any manual operation. The Fan cycle mode periodically circulates air for comfort. To adjust temperature settings, simply turn the scroll wheel to the right or left.

The Omnistat2 can display outdoor temperature and humidity settings as well. A graphical chart can be viewed showing HVAC usage/energy consumption, sorted by week. The display includes a filter reminder to keep your systems at peak efficiency. Omnistat2 thermostats do not require batteries to retain their settings and time.


Wireless Omnistat2 thermostats utilizing ZigBee Home Automation technology are perfect for new construction and residential or small commercial retrofits. These do not require additional wiring to connect the thermostat to the automation controller as they communicate wirelessly. These thermostat models provide additional wireless controls over individual high-draw devices such as pool pumps, fountains, signage, or other motors/fans.


The Omnistat2 may be used stand-alone or with a Leviton security and automation system. When used stand-alone you may schedule your HVAC activity with an easy-to-use 7 day schedule function. You can set back the equipment when the house is not occupied and save on your energy costs. The Omnistat2 has a built-in vacation mode feature that restores temperatures automatically ensuring a comfortable return and energy savings.

Omnistat2 thermostats allow you to have a different program option for every day of the week, which makes them flexible enough for home or business owners with varying schedules. Additionally, the thermostats have a simple copy and paste feature to make it easy to copy a program schedule from one day to the next (perfect for most M->F schedules!).


Omnistat2 thermostats communicate with Leviton automation systems, as well with other manufacturer’s automation systems. When you add an optional Leviton automation system to the Omnistat2 thermostats, you get comprehensive energy management capabilities. Temperatures and humidities may be controlled via events, such as the setting of the alarm system or motion detection. Additionally, the automation system has automatic temperature setbacks for Home, Night, Away, and Vacation. Finally, full control of every Omnistat2 thermostat is available on built-in Touchscreens and mobile devices like smartphones or tablets.


Omnistat2 thermostats support one external temperature sensor for indoor or outdoor temperature monitoring. When an outdoor sensor has been set up, the outdoor temperature is displayed on the Advanced Display of the Omnistat2 and can be seen on other user interfaces. The temperature from a remote temperature sensor can be combined with the onboard Omnistat2 temperature sensor to determine the average temperature of two locations, and this average temperature may then be used for comparison to heat/cool set points. The RC-2000 model even features a built-in humidity sensor.


The Omnistat2 is available in three different colors - White, Black, and Silver - ready to match your décor. The LCD's multi-color backlight means you can choose from over one hundred different backlight options. Omnistat2 thermostats have a built-in proximity/motion detector so that the screen illuminates when approached, enabling quick adjustments even in the dark of night.

For further customization, the Omnistat2 features both simplified and advanced display options. The simplified display has large numbering for current temperature and is perfect for viewing across the room or for those who are hard of sight. The advanced display shows the cool and heat setpoints along with the day of the week and the relative humidity.
