- Set temperatures between 4° & 99° F with X10 signals
- Report temperatures between -60° & 131° F
- Retain complete manual control from the thermostat
- Works with standard and heatpump systems
Get complete local and remote control of virtually any thermostat function with this X10 Bi-Directional HVAC System that not only responds to X10 commands, but also has the ability to send reports via X10. When used with an intelligent home control system, you can have your system automatically respond with any action (i.e. turn on a ceiling fan, open or close dampers, etc.) when certain temperatures are reached. Yet with all its advanced, automated features, the system still offers the complete, manual control that you have with ordinary thermostats.Adjust the house temperature in the morning from an X10 controller that you can keep on your nightstand
Responds to X10 Commands
With a simple X10 command, the system can set any temperature between 60° and 90°F, or a low temperature setting of 40°F. You can also use X10 to access other features, such as HEAT/COOL, AUTO, and OFF functions. These functions allow you to do things like:
Make sure your house is the perfect temperature when you get home with any X10 timer
Control the temperature with a phone call with an X10 telephone transponder
Responds to Status Requests
If you have an intelligent X10 controller or home automation software that can send & receive advanced X10 codes, such as pre-set dim and request status, this system will respond to those commands. Systems that can directly control this bi-directional thermostat and understand its signals include:
Home Control Assistant
RCS CommStar network Controllers
Depending on the controller, the X10 Bi-Directional HVAC System can provide it the current temperature. This information can be used to make decisions, run macros, or notify you that something is wrong.

Optional Expansion AccessoriesThe X10 Bi-Directional HVAC System works with almost all heating and cooling systems, including standard Gas/Electric, Heat Pump, Radiant, or Hydronic systems and with single or multi-stage systems. Compatible with single or separate transformer heating/cooling systems.
Wall Mount Remote Temp. Sensor This optional Wall Mount Remote Temperature Sensor replaces the internal temperature sensor in the Wall Display Unit with an external sensor. This allows you to control and monitor temperatures in locations away from the display unit. Also, if the present location of your thermostat does not accurately sense the home's average temperature, you can place this unit in the optimum location. Manufacturer's part number: RS15.
Pool/Spa Remote Temperature Sensor With the optional remote sensor you can even monitor temperatures in locations away from the RCS display unit. The sensor connects to the Wall Display Unit. Manufacturer's part number: RSP1/RSP2.
