13.4.4. Selecting the operating mode
To launch the unit, the user must select the desired mode in the menu:
• Delegate: the current mode is determined by
the BMS or by default by the calendar (refer to
the user manual)
• Off: Unit is stopped
• On: System is launched
• Reduced: Refer to the § “Reduced mode”,
page 35
• Limited capacity: Refer to the § “Limited
capacity”, page 35
The “State from” line states which element requested the current status:
• Cont.off: on/off digital input
• Cont.ext: D2 confi gurable digital input (in “Reduced mode” or “Limited capacity”
• HMI: User interface
• BMS
• Schedul
13.4.5. User temperature setpoints and actual setpoints
In the Status menu, the user can set start or
return temperature setpoints, according to the
control mode selected:
• Cooling setp: temperature setpoint for the cool
mode
• Heating setp: temperature setpoint for the heat
mode
These setpoints are fi xed and restricted to the
unit’s operating limits.
They can however be adjusted with the “Water
law” and “Reduced mode” options, which are
deactivated by default.
Regardless of the adjustment, the resulting setpoint is restricted to the operating limits to protect
the unit.
Actual heat and cooling setpoints correspond to values used in real time, account taken of any
adjustments and protections.
