Description
The EDH3321112 is a network enabled room LCD display operator unit complete with built-in temperature sensor for controlling temperature in an area served by a Fan Coil Unit such as individual room or office in commercial buildings. Couple with EC series controllers, the EDH3321112 able to include fan speeds and temperature control function. The EC series controller contains a library of pre-programmed cooling / heating / fan speeds applications so that no additional user programming is required. To be fully functional, the operator needs to choose the most suitable pre-programmed application, set the EDH3321112 device address to ensure device addressers are unique on the same network and set the required temperature and fan speed set-points.
The EDH3321112 can be operated as a stand-alone or networking mode with other EDH3321112 to be part of the large HVAC system. This networking function enables integrated control, monitoring, alarm and logging functions of the complete HVAC system to ensure optimum building environment comfort and energy usage. The EDH3321112 support communication speed of up to 76.8k baud which allows rapid access to information within the whole HVAC system. The EDH3321112 built-in temperature sensor is inter-changeable without the need of recalibration because of the used of miniaturize electronic circuits. The EDH3321112 is a plugged-in construction that ensures fast and simple installation, thus greatly reduce installation and maintenance costs. The EDH3321112 enclosure is made of ABS plastic.
