Efficient control

Climatic temperature control

A climatic control system is the more efficient way of controlling temperature and offers the greater energy savings.

The amount of heat required to maintain conditions of comfort in a room is linked to external temperature and a buildingā€˜s heat loss. Heat requirements increase with decreasing external temperatures and increasing building heat loss. A climatic control system allows you to select a heating curve from among a set of curves, allowing the settings to be adjusted to the specific building.

Once the heating curve has been set, the flow temperature to the system is regulated automatically according to external temperature, adjusting the heat input to the heat demand of the building and thereby ensure continued optimum comfort.

The system does this using a digital electronic control unit to which two temperature probes are connected - one to measure external temperature and one to measure the system flow temperature - and a servomotor. which drives the mixer valve.

The control unit processes the signal from the external probe and, based on the climate code that most suits the building type, determines the ideal value for the flow temperature, comparing it with the actual value measured by the supply probe and, if necessary, operating the mixer valve.

Climatic control adjusts the flow temperature based on heat required.

Climate according to building:
The slope for flow temperature depends on the heat requirements of the building!

The climatic curve or heating curve is the relationship between the external temperature and the flow temperature to the heating bodies calculated by the climatic regulators. Two parameters are required to scale the curve correctly:

  • Minimum external design temperature, for example Milan -5°C
  • Maximum flow temperature to the floor system, for example 40°C floor system

Knowing these values allows us to link the two corresponding lines on the graph, thus producing the curve.
