The Economizer Controller can receive an occupancy signal from the connected thermostat or work under Occupied mode all the time. This is configurable in the Thermostat setup from Climatix Mobile or under the menu of I/O Configuration on the inbuilt display. See I/O Configuration for more information.
On the call of cooling when the controller is configured to receive signal from the thermostat but the thermostat is working under the Unoccupied mode, the damper is fully closed if free cooling is disabled or if there is no heating/cooling demand. If outside air is suitable for economizing and there is cooling demand, the damper can be opened normally. If the thermostat is working under the Occupied mode, the damper at least opens to the minimum position unless MAT-based anti-protection is enabled.
