Display
Upper digits (red color): configurable, see parameter CF36 (PB1, PB2, PB4, Set-point
(parameter value)*, working set-point (real set-point modified from dinamic set-point,
Energy saving or function for units without water storage tank), Hysteresis, Machine
status **))
Lower digits (yellow color): configurable, see parameter CF43 (PB1, PB2, PB3, PB4,
Set-point (parameter value)*, working set-point (real set-point modified from dinamic set-
point, Energy saving or function for units without water storage tank), Hysteresis, RTC,
Machine status **)).
*the display visualizes chiller set point when the unit is on and in chiller mode, heating
set point when the unit is on and in heat pump mode, and OFF when the unit is in
standby.
**the display visualizes OnC when the unit is on and in chiller mode, OnH when the unit
is on and in heat pump mode, and OFF when the unit is in standby.
