Current regulations require having display screens available to continuously monitor temperature and relative humidity at facilities such as operating rooms and clean rooms among others. The e-Clima display screen is a simple device that includes a wide LCD and allows the monitoring of temperature, relative humidity and pressure values of remote sensors.
This device is designed to receive the weather values over a communication bus. For this purpose e-Clima features a standard EN 14908 (LonWorks) bus enabling the reception of values from sensors located anywhere in the room. The e-Clima display also includes an analogue input for the direct connection of a temperature sensor such as the e-Temp device; if this option is chosen, using a LonWorks temperature sensor will not be required and thus reducing the cost of the installation.
Two possible configurations are available to install e-Clima:
1) Installation of sensors featuring LonWorks communication. In this case, sensors will include a Lon communication port and will transmit weather values over the bus on to the e-Clima display.
2) Installation of analogue sensors and value conversion to LonWorks bus through an analogue input module. In this case, standard commercial sensors may be used featuring a 0-10 V or 4-20 mA output, which will be connected to an analogue input module for signal conversion to Lon protocol. This information will transmit through network variables to the e-Clima display.
Furthermore, the communication bus allows remote monitoring of the facility at all times, such as from a maintenance centre, thus enabling remote parameter display and alarm setting for HVAC failure, humidity, etc.
