CONTROL SYSTEM OF A HVAC (HEATING, VENTILATION AND AIR-CONDITIONING) SYSTEM
The invention relates to a method of controlling the temperature in a conditioned zone in an energy saving (ECO) mode. In an active mode, before switching to ECO mode, the fluid flow is controlled within a deadband defined around the "active" temperature setpoint.

The ECO cooling setpoint is activated (B) and the controller starts controlling the temperature within a deadband around the ECO cooling setpoint. Whenever the temperature falls below the lower boundary of the deadband, fluid flow is reduced to Vmin and all local cooling aggregates are switched off. When the mode is changed to active mode (C), regular control is activated and the temperature is controlled within a deadband around the active setpoint.
