We are glad to introduce our new application for controlling the temperature of a room in a centrally air-conditioned environment when paired with the built-in wifi server & Micro-Processor Based Temperature controller developed by us. The application has the provision to set the motor speed of the air handling unit through VFD and maintain the temperature of the room through PICV or condensing the Unit in accordance with the desired set temperature by the user. It also has the provision to monitor the real-time temperature of the room.
