All available information is supplied through the serial RS485 line. It is available through
both RJ45 plugs located in the front of the control panel and in the plug behind the
control unit.
A PC program for testing and troubleshooting is also an option.
The number of the unit is defined through a binary DIP converter located on the control
unit. The factory setting is 0.
Setting:
Back-up
Dip switch no. 6 has been reserved for back-up setting.
When the switch is set on ON, the unit will function as a back-up unit. This could be
preferable in situations where there are other primary cooling units in the shelter.
In back-up condition the unit will be standby and not running, unless the adjusted
cooling and heating set point is registered by the return air temperature sensor. See
more about this in section ”Fan”, page 9.
