Solar Fan Overrides
Off Button – Shuts the fan off. This setting remains at the off position until another fan speed button is pressed.
Half Speed Button – Limits the fan speed to approximately 50%. This setting also prevents the boost mode from operating. This setting remains in this position until another button is pressed.
Full Speed Button – Allows the Powertrack controller to boost the fan speed automatically. Under this setting the fan speed will be dictated by the power of the sun. This setting remains in this position until another button is pressed.
VCD Positioner
- Turn dial positioner allowing 0 to 100% damper control.
- When set to closed the fan is automatically shut off.
- When opening the damper again the control panel remembers the previous position of the fan and sets the fan to run again if required.
Internal Temperature Sensor
- When the internal temperature is below 20°C the fan is
prevented from running.
- When the internal temperature is below 15° the damper will automatically close to prevent over cooling an internal room.
- When the internal temperature reaches above 24°C the damper will automatically open to automatically ventilate the internal space.
On the basis of these three instructions these override all other settings. |
