Patent

CA 2126925

A setback control for an HVAC system is selectable by depressing a switch on a control panel associated with a programmed microprocessor. The programmed microprocessor is operative to thereafter change the setpoint temperature by a predefined amount each hour until a predetermined number of hours have passed. The set point temperature is thereafter held for a further hourly count before being returned to the starting setpoint temperature. The directional change in setpoint temperature is a function of whether the HVAC system is in a heating or cooling mode of operation.

Il est possible de régler une commande de remise au point de consigne d'un système CVC (chauffage, ventilation, climatisation) en abaissant un sélecteur sur un panneau de commande associé à un microprocesseur programmé. Le microprocesseur programmé permet ensuite de modifier d'une quantité prédéfinie la température du point de consigne à toutes les heures jusqu'à ce qu'un certain nombre d'heures soit passé. Ladite température est ensuite maintenue pendant un deuxième compte d'heures avant d'être remise à son niveau initial. Le changement de direction de ladite température dépend du mode de fonctionnement du système CVC : mode chauffage ou mode refroidissement.
