HAI’s Omnistat2 programmable communicating thermostats (PCTs) are a flexible product designed for use by utility companies for Home Area Network (HAN)
use in Smart Grid programs. The unique design of the Omnistat2 allows it to be used as a thermostat and an In Home Display (IHD)
at the same time.
The Omnistat2 utilizes an easy to understand Multicolor Display that can change colors in
response to utility related events. The Omnistat2 thermostat communicates with smart meters and can be
used to display and control HAI’s other HAN products, such as
Load Control Modules (LCM).
The Omnistat2 thermostat may be controlled by HAI's IHD.
Omnistat2 thermostats
provide
precise digital temperature control over the Heating & Air Conditioning (HVAC) system
using
advanced digital technology that learns the heating/cooling patterns of the home to
control the equipment for maximum efficiency and comfort. Omnistat2 thermostats stand out against their competition!
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.
Omnistat2 thermostats do not require batteries to retain their settings and time.
The Omnistat2 user interfaces are intuitive and easy for the homeowner to use.
Thermostat pages can be customized to provide any type of energy awareness information that a customer may require.
Omnistat2 thermostats can provide real time feedback for customers about their usage in a simple easy to
understand format, including providing charts and graphs of HVAC usage, total energy consumption,
comparative analysis with typical energy usage, and even Carbon Footprint data.
The graphic energy display can change color as an easy way to show energy state or events.
When available from the utility, the Omnistat2 shows the current cost of energy,
how much energy the homeowner has used,
and the current cost of the homeowner's utility bill.

The homeowner may change the backlighting from blue to red or any color in between by turning the knob. This
capability, adjustable at any time, provides the homeowner with over one hundred customizable backlight colors.
The RC-2000 and RC-1000 Omnistat2 thermostats have a proximity/motion detector so that its screen lights up
when it is approached, which makes it easy to adjust in the dark of the night.

|
The Omnistat2 can optionally display outdoor temperature and humidity. It has a
filter reminder for peak efficiency.
The homeowner may switch between a simple or advanced display, based upon what information is
desired to be viewed.
Programmable
The homeowner may schedule HVAC activity using a easy-to-use 7 day schedule function.
The equipment may be set back
when the house is not occupied in order to save on energy costs.
The Omnistat2 has a built-in vacation mode feature that restores temperatures before arriving home.
Omnistat2 thermostats allow homeowners to have a
different program option for every day of the week, which makes them flexible enough
for homeowners who have different schedules every day. Additionally, these thermostats have
a copy feature to make it easy to copy a program
schedule from one day to the next.
Communication
Both Omnistat2 thermostats and IHDs (shown at right) are capable of acting as a ZigBee® coordinator, which means that they can be
used to control Load Control Modules (LCMs) and thermostats for increased ease of use by the homeowner.
Omnistat2 thermostats support one external temperature sensor for
indoor or outdoor. When an outdoor sensor has
been set up, the outdoor temperature is displayed on the Advanced Display of the Omnistat2.
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.
Omnistat2 thermostats communicate with HAI home control
systems, as well with other manufacturer’s automation systems.

Surface Mount Remote Indoor Temp Sensor
Manual
The Surface Mount Remote Indoor/Outdoor Temperature Sensor may be mounted in the conditioned space
and the thermostat can be mounted remotely for protection from
tampering or for aesthetic reasons.
This sensor may be used by Omnistat2 thermostats as an outdoor sensor for dual fuel heat pumps.
This sensor uses twisted pair, shielded cable from the Omnistat2 or Omnistat thermostat to
its location.
-
For distances up to 100 feet,
typical twisted pair, PVC-insulated, shielded cable may be used.
- For distances from 100-150 feet, twisted pair with polypropylene insulated conductors,
shielded must be used.
- For distances from 150-250 feet, twisted pair with foam-polyethylene insulated conductors,
shielded must be used.
- Wire runs must not exceed 250 feet.
The Remote Sensor must be mounted in the same location appropriate
for a thermostat for best performance (for example, on an inside wall,
free of draft from vents, away from sunlight, windows, etc.).
This small (2 W X 1.5 H X I D inches) unit is mounted on the surface of the wall.
This sensor will work with any Omnistat2 thermostat.
