7.7 Night-time operation
During night-time operation there may be a decrease in thermal load. To avoid excessively low temperatures and high energy
consumption, the set point needs to be increased at night by setting parameter r4. Parameter r6a can then be used to select the
virtual probe Sv or air on probe Sr as the control probe.

Tab. 7.h
Night-time operation can be activated by a digital input confi gured as a curtain switch, on the user interface, from the supervisor
or time bands, with diff erent priorities. If the digital input has been selected, this has the highest priority and the other actions
are ignored, while if the digital input has not been selected, the other actions have the same priority and the last one controls
the action.
To set the time bands, see “Setting the date/time and time bands”.

Notice for HACCP: verify that modifi cation of the night-time set point (parameter /4) is permitted by site HACCP procedures.
If required, obtain the required authorisation and record the changes.
