PRODUCT OVERVIEW The GES2181 Energy Saving Thermostat can connect to 3 Heat / 2 Cool conventional Heat Pump HVAC systems. The thermostat’s smart ZigBee™ technology enables it to communicate with your utility company so you can receive messages about energy saving events and price reductions. In addition, the easy‐to‐use interface makes it simple to control your energy consumption.

When the vacation mode is activated, your utility company can override your temperature setting when the new event setting saves energy, for example: a) In wintertime when the outdoor temperature is cold, you may set your vacation temperature to 10°C to prevent pipes from freezing. However, if the utility company sends an event to reduce the temperature to 8°C to save energy, it will override your vacation temperature and make the new ‘Heat Set Point’ 8°C.
