When starting up, the software version is shown in the display for
about three seconds. Then the thermostat enters run mode (except
the programmable thermostat which may require the time and date to
be set).

8 seconds, while in a submenu, the current values will be

about 60 seconds later, it exits to run mode.

long, the software requires the time and date to be set. This setting is
required to utilise scheduling programs for this thermostat.
