TRANSLATION OF THE ORIGINAL INSTRUCTIONS 70
After enabling time bands from the “Enable time bands” parameter in the “Scheduler” menu , time bands can be set and different setpoints can be specified according to
requirements.
The following must be defined to ensure correct use of the time bands:
1. The type of programming of the time bands:
o
Standard : For setting a single programming category (A), with a maximum of 10 time bands, that can be assigned to each day of the week.
o
Advanced : For setting up to 4 different types of programming category (A, B, C and D), with a maximum of 10 different time bands, that can be
assigned to each day of the week.
2. For each day of the week:
o
Disable the time bands: On the day selected, the controller runs without the time bands.
o
Enable a type of time band (A, B, C or D): On the day selected, the controller runs as programmed.
3. For each time band:
o
Unit status: OFF (unit turned off by time bands) or in adjustment mode (unit turned ON by time bands).
o
Time band start time (for the first time band, this is fixed at 00:00).
o
Time band end time (for the tenth time band, this is fixed at 23:59).
o
Cooling setpoint.
o
Heating setpoint (when applicable and configured).
INFORMATION
The time bands B, C and D are shown only when Advanced programming is selected.
INFORMATION
To use a smaller number of bands, simply set the time a band ends to the same time it begins. In this way, the band in question is ignored.
Below are a few examples that, in graphical form, use bands A, B and C in the clock menu.
The weekly chart uses band A for Monday, band B for Tuesday, Wednesday, Thursday and Friday, and band C for Saturday, while for Sunday the bands are disabled.

Using the supervision protocol
Only if the serial board is fitted.
Check in the
“User menu” that the parameters “Serial line enabling” and “On/Off enabling from supervisor” are set at “Yes”.
Proceed as follows:
• Switching On : Send the switching on command from the protocol. The corresponding icon is displayed in the main mask.
Note : The unit doe s not switch on if it is set to “Off from keypad” or “Off from digital input”.
•
Switching Off : Send the switching off command from the protocol. The corresponding icon is displayed in the main mask.
3.4 START OF AUTOMATIC ADJUSTMENT
Temperature and humidity adjustment is enabled 60 seconds (settable time, minimum value: 20 seconds) after the unit is activated, that is, after ventilation is started. The
aim is to give the unit time to circulate the ambient air for long enough to assure correct reading of ambient temperature and humidity values.
Automatic adjustment permission is immediately withdrawn when ventilation is disabled or when the manual commands are enabled.
