Only Heating / only Cooling

These operating modes follow the same rules as in HEATING / COOLING
(automatic mode). The selected mode is activated as soon as the
conditions are fulfilled.

Heating / cooling manual

Selection of these modes overrides the above listed "soft" conditions
(but not digital signals HEATING or COOLING coming from external)
and the selected mode starts immediately.
These modes allow the user to start heating or cooling whenever it is
possible in terms of available supply from boiler or chiller.
This mode can be used for testing during servicing and installation.
4.1.4

Energy levels

The energy level defines not only the temperature set points in the
operating modes HEATING and COOLING, but also the operation of
dehumidifiers and fan coils.
An energy level may be activated manually, by timing program or by
the geofencing function of the App. An energy level is valid for the
complete installation, a selection of rooms or a specific room.
Remark:
The system optimizes the transitions between NORMAL
and REDUCED mode to ensure comfortable conditions and to
reduce energy consumption.
Please note also:
The installed heating or cooling systems have physical limits, which
have to be considered, when set points and timer programs are
defined.
- During summer, e.g., it is not possible to reach a room temperature
of e.g. 21 °C in cooling mode by means of an underfloor cooling
system only
- It makes no sense to define short time spans per energy level trying
to raise/or lower the temperature by 3 degrees for an hour and then
to reverse it again because the underfloor system cannot respond
that quickly
There are 4 different energy levels:
NORMAL
Energy level NORMAL should be active when the room is occupied.
Default temperature set points:
Heating: 21 °C
Cooling: 24 °C
REDUCED
Energy level REDUCED should be active when the room is not occupied.
Default temperature set points:
Heating: 19 °C
Cooling: 26 °C
PARTY mode
PARTY mode switches the energy level in the selected rooms to
NORMAL for a default period of 4 hours. When selected via the App,
the activation period can be freely chosen.
HOLIDAY / ABSENCE
Energy level HOLIDAY / ABSENCE is activated for time spans, which
are longer than 1 up to 3 days, (depending on insulation standard of
the building).
Default temperature set points:
Heating: 15 °C
Cooling: not active
The temperature set points for NORMAL, REDUCED
mode (heating/cooling) and HOLIDAY mode (only
heating) can be set on the room configuration pages of the App
or on the web pages.
STANDBY
The energy level STANDBY is used for rooms, which are not used for
an extended period of time.
Default temperature set points:
Heating: 8 °C (freeze protection)
Cooling: not active
The ranking of energy levels in terms of comfort and
energy usage is (from high to low):
NORMAL  REDUCED  HOLIDAY  STANDBY
