A Remote Terminal Unit (RTU) HVAC is a type of heating, ventilation, and air conditioning (HVAC) system that is used to control and monitor the temperature and air quality of a building or facility. It is a computerized system that is connected to the HVAC system, and it is able to monitor and control the temperature and air quality of the building or facility. The RTU HVACHVAC system is typically connected to a central control system, which is responsible for controlling the system and sending out commands to the RTU. The RTU is able to receive these commands and then adjust the HVAC system accordingly. The RTU is also able to provide feedback to the central control system, such as temperature readings and other information. The RTU HVACHVAC system is an important part of any building or facility, as it is responsible for ensuring that the temperature and air quality are kept at an optimal level. It is also responsible for reducing energy costs, as it is able to adjust the HVAC system in order to maximize energy efficiency.
