Taking room temperature control into the next millennium

    The XE88 brings room temperature control into the 21st century. Its state-of-the-art microprocesssor-based technology ensures the most accurate temperature control available on the market today. Add to this its ability to help you save energy by interfacing with occupancy sensors or other energy-saving devices, and you have a win-win business proposition.

Using the latest state-of-the-art technology, the XE88 ensures the highest level of comfort in any room. It is suitable for use in a variety of settings, including hotels, offices, hospitals and others. The microprocessor-based thermostat uses a Proportional plus Intergral (PI) algorithm to ensure precise comfort control.
     
     
  Easy to operate
    The XE88 has a clear LCD digital display that can be viewed from any angle. A simple up-down electronic keypad provides hotel guests with an attractive and functional thermostat that is easy to operate and ensures complete comfort.
     
     
  Easy to install
    The XE88 makes life easy for the installer. The direct line voltage input eliminates the need for additional tranformers and connectors. A separate sub-base allows the installer to complete all wiring work before mounting the thermostat, avoiding possible damage or theft at site.
     
     
  Easy to service
    In case of a power failure, an EEPROM in the XE88 permanently retains the last user settings. A built-in self test program will pinpoint any fault the first time it occurs, so that no time will be wasted on defective unit replacement.
     
     
  Energy saving
    The XE88 allows for direct interfacing to energy saving devices such as hotel card key systems. The card key input overrides the room guest's temperature setting to an installer-defined setpoint when a guestroom is unoccupied, in order to minimise energy consumption.
