There is not a way to schedule an outside damper to be at 100% open before occupancy. However, the pre-occupancy ventilation recommendations established by ASHRAE assumes that the outside damper is at its minimum position and not 100%. With it at the minimum position, the target is four complete indoor air changes during a 1 hour period. This position also assures that the heating and cooling system can keep up with maintain the indoor air temperature.
For normal pre-occupancy ventilation, the thermostat should be scheduled for Fan set to ON one (1) hour before occupancy with Outside Ventilation* set to ON.
To prevent the spread of COVID-19, ASHREA has recommended to increase the pre-occupancy ventilation to two (2) hours before occupancy. Click here for more information on how to use your Pelican solution to maintain proper indoor ventilation rates to reduce the spread of COVID-19.
*Outside Ventilation
