THERMOSTAT WITH EPIDEMIC CONTROL VENTILATION

원문 (중국어)

A controller for controlling HVAC equipment in a building includes a processing circuit configured to receive an occupancy schedule indicating at least one of a first occupied period or a last unoccupied period for a space in the building for a schedule period and receive a user input indicating the space should be purged based on occupancy. The controller selects, based on the user input, at least one of a pre-occupancy purge mode or a post-occupancy purge mode. The controller is further configured to control the HVAC equipment to ventilate the space for a purge duration prior to the beginning of the first occupied period in response to selecting a pre-occupancy purge mode, and ventilate the space for the purge duration at the beginning of the last unoccupied period in response to selecting a post-occupancy purge mode.
