3.19.1 Option management
The unit may be fitted with some options.
After installation, option management must be enabled in the controller.

Options that require enabling in the controller include:
- heaters;
- fire/smoke alarm;
- static pressure/differential pressure probe;

air quality probe.
These functions are enabled in the screens containing the “SP - Setup” parameters. Access to these screens requires entry
of “Service” credentials.
When a function is enabled, the inputs and outputs required for operation are automatically activated.
Refer to the instructions supplied with the option for the installation procedure. Refer to the wiring diagram for the electrical
connections.
The controller must be restarted to make any change active.
When an option is enabled, a request for controller restart appears automatically in the form of a message on the display.
A countdown appears in the message window, which can be bypassed - the restart procedure is started immediately - or
delayed. If none of the two actions above is selected, the controller gets restarted at the end of the countdown.
If the restart procedure is delayed, the controller will automatically display a restart message after a few seconds.
The controller may also be restarted by de-energising and then re-energising it.
