Displaying the operating data overview
On the "Overview" information level, the RoCon mb controller's
display shows the current operating data for the ROTEX HPSU
monobloc compact.
The display of the operating data is split over several screen
pages. Adjust the rotary button to navigate between the screen
pages.

Current heat pump energy mode:
LT: EVU function HT/NT active and off-peak.
HT: EVU function HT/NT active and peak.
SGN: EVU function Smart Grid active, normal
operation.
SG1: EVU function Smart Grid active, shut-off: no
heat pump operation, no frost protection function.
SG2: EVU function Smart Grid active, switch-on
recommendation, operation at higher target
temperatures, inexpensive electricity.
SG3: EVU function Smart Grid active, switch-on
command and storage tank charging to 70 °C,
inexpensive electricity
- - -: No external mode active, heat pump operates
in standard mode.
