NR9003 is a digital controller that allows to manage both the heating and cooling of the mixing group of a radiant panel system with a maximum of 9 independent zones through temperature and relative humidity sensors positioned in each single zone acting on positioned electro-technical actuators on the distribution manifold. In addition, the controller is able to enable a possible dehumidifier on the basis of the relative humidity measured in the rooms for humidity control and as a safety against possible condensation during the summer.
The STA61M temperature and relative humidity sensors are connected to the controller via a Modbus communication bus and allow the setting of a time set-point (daily and weekly) and a relative humidity set-point for each individual zone.
NR9003 can also be supervised via PC or Tablet with the MT-NET-PON3 Operator Panel.
