  • Page 8: Control Logic

    Messana PID temperature control logic mZone can dynamically modulate the fluid supply temperature when is combined with an hydronic mixing and pumping station. The mixing station features a high efficiency recirculating pumps, a motorized 3-way proportional mixing valve (0-10V or 2-10V) and two temperature probes installed on the supply (S) and return pipes (R). This configuration allows to a PID (Proportional Integrative Derivative) control loop with temperature feedback mechanism.
  • Page 9 The Messana PID control logic evaluates the supply temperature (target crosshai) 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.
