This gorgeous thermostat has an extra pair of connections, and two temperature settings. When you short the extra contacts together, the thermostat uses the 'night' setting (which could also be an 'away' or 'anti-freeze' setting.) Run an extra pair of wires from the thermostat to something that can connect the wires via remote control, and you have a remotely controllable thermostat!

There aretwo basic ways to hook up this thermostat: Run the two wires to a Universal Module. Plug in the Universal Module and you can send X-10 commands from any X-10 controller (including a telephone transponder) to operate the thermostat. This mode is quite popular with the 'mountain cabin' folks. Imagine calling your cabin from your cell-phone while on the way to tell it to warm up the place! And always being assured that, when away, the thermostat will not let the pipes freeze.

Energy Management

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

The Omnistat2 thermostats are the latest generation of programmable communicating thermostats. They combine HAI’s 20+ years as a leader in energy management to provide sophisticated and intelligent function in an easy to use device.

What sets the Omnistat2 thermostats apart from other thermostats 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.

The Omnistat2 may be used stand-alone or with a home control system. When used stand-alone you may schedule your HVAC activity using a easy-to-use 7 day schedule function. The Omnistat2 has a built-in vacation mode feature that restores temperatures before arriving home.

The Omnistat2 can display a graphical display of HVAC usage/energy consumption by week and has a filter reminder for peak efficiency.

The Omnistat2 is UL Listed for energy management.
Style

The Omnistat2 has three different color options, Black, Silver, and White, in order to match nearly any décor. The thermostat does not come with color change kits - you must purchase the thermostat in the desired color.

You may change the backlighting from blue to red or any color in between by turning the knob. This capability, adjustable at any time, provides you with over one hundred customizable backlight colors, The RC-1000 Omnistat2 has 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.

Choose between a simple or advanced display, based upon what information you want to view.

Use this thermostat for full RS485 control of your HVAC system. It installs in two pieces: The thermostat, which replaces your existing thermostat. And the control unit, which goes back by your HVAC equipment. The control unit and the thermostat talk over the same wires that your old thermostat used. (4 conductors min.) The control unit has a plug-in power supply and a RS485 connection. The control unit connects to the HVAC equipment where your original thermostat wires connected.

For control, you can adjust the mode and temperature setting at the thermostat, or send RS485 commands from a whole-house controller such as HomeVision or a PC.

Remote temperature sensor available. RS15 .

Use this thermostat for full X-10 control of your HVAC system. It installs in two pieces: The thermostat, which replaces your existing thermostat. And the control unit, which goes back by your HVAC equipment. The control unit and the thermostat talk over the same wires that your old thermostat used. (4 conductors min.) The control unit has a plug-in power supply and a TW523 to receive the X-10 commands. The control unit connects to the HVAC equipment where your original thermostat wires connected.

For control, you can adjust the mode and temperature setting at the thermostat, send X-10 commands manually from any X-10 controller or from a whole-house controller such as ActiveHome or HomeVision. Use this small remote temperature sensor with the TXB16 thermostat. It connects to the thermostat with four conductor wire. Place the remote sensor near an air return duct for best results.

Sensor is only 1.5' X 2' X 1' Thick.

The HVAC Zone Controller converts a single heating and cooling system into an intelligent comfort control system that provides independent temperature control of two to four zones within the home.
