3.2.2 Heating Control
Heating startup point = Heating on point - Heating sensitivity. In order to protect the
internal equipment, when the internal temperature below the heating on setting point,
the unit begins heating, when the cabinet temperature is higher than heating off point,
heater stops operating.

3.4 Hydrogen Discharging/Emergency Fan (Optional)
The hydrogen discharging/emergency fan will provide automatic-cycle hydrogen
discharging according to the requirements of the environment inside the cabinet. The
interval between each automatic cycle hydrogen discharging is 24 hours (adjustable) and
the discharging time is 5 minutes (adjustable).
When the cabinet is over-temperature, a system failure occurs, or the external
temperature is low, the hydrogen discharging/emergency fan will be started to provide
forced ventilation.
3.5 Monitoring
The Heat exchanger is supplied with a RS485 control interface offers a variety of
information output. For detailed information, please refer to the protocol list.
If you need to adjust the set point, you can connect heat exchanger and computer with
RS485 ports, through the background monitoring software or handheld monitor to make
changes.
Note:
To prevent unauthorized setting changes, make sure only qualified people are
permitted access.
