The Messana PID control logic evaluates the supply temperature (target
crosshairs
) based on how far is each zone from the
desired set-point (proportional), how long is in that status (integrative) and how quick the radiant terminals reacts
to the fluid temperature change (derivative). This technology allows to deliver just enough heat (or cool, by heat
extraction) to always meet the actual internal loads and maintain the correct room operative temperature within a
0.5F differential.
With the PID control logic the radiant system achieves optimized performance in terms of energy efficiency and
comfort maintaining always an accurate and uniform indoor temperature.
The PID control logic regulates the supply water temperature, and ultimately the room temperature, based on the
three different actions:
Actions
Based on
Proportional
The actual value of the room temperature
Integral
The past values of the room temperature
Derivative
The expected variation of the room temperature
