4.6.5.2 WEEKLYPROGRAMMINGFANCOILZONE
In a similar way to the scheduling of chillers, a weekly program of each zone can be set (independently between summer and
winter),withminimumstepsof15minutes.
Thepossiblesettingsare:
• Offzone;
• Normaloperationzone(normalambientset‐point);
• Economicalfunctionzone(economicambientset‐point).

The procedure for configuring the programmable chronothermostat is therefore similar to those described above,
with the only
differencethatthechoiceoftheoperationisonlybetween"Normal"and"Off"(seefigurebelow).
