HVAC Panel For Dual AC Units

This is a ready to use HVAC panel for operating two independent air conditioning units in the cyclic mode, based on the programmed time and the temperature settings. It is designed to control the room temperature in the cold storages, computer server rooms, etc. Normally in applications where round the clock guaranteed low set temperature (15-20?C) is to be maintained and to decrease the burden on a single AC unit, two ACs are installed. The main control unit Model LST-300 is a microprocessor based controller, which accepts the temperature sensor Pt-100 as the input and displays the same on the digital display. The user is allowed to program the On and Off cycle time. Each AC unit operates for the programmed On time and at the same time the over-riding logic acts to simultaneously operate both the AC units, in the event the room temperature rises above the set value, and on temperature coming down below the set value, one of the AC unit is turned off. The panel is easy to install and user friendly to operate. Suitably rated input and output terminals are provided inside the panel for power and load connections. To accurately sense the room temperature, Class A Pt-100 sensor with 10 mtr cable is also supplied along with this panel.
