A rooftop unit (RTU) is a system that has all the necessary equipment to transfer heating, cooling and ventilation into a building through ductwork.
It is the ultimate unit to provide comfort and optimize indoor conditions for occupant health and comfort, and business activities.
The control section of a rooftop unit may consist of two cooling stages, two heating stages and a fan activation terminal. With this is mind,
Neptronic has designed the TRT2422, a precise temperature controller that can be directly wired to the rooftop unit. It includes a programmable
proportional-integral (PI) algorithm and a 7-day scheduler.
Projects that need remote control from a direct digital control (DDC) or automation software are better implemented with one of Neptronic’s two universal
controllers. The TUUB or TUCB series are models specifically for straightforward and precise control of rooftop units. They include BACnet and Modbus as
standard communication protocols.
