The min. fan speeds for Comfort, Precomfort, Economy and Protection (P153, P156,
P157 and P158, see page 129) must be set to a value that guarantees that the full heat
of the electric heater can be dissipated.
11.3 Temporary Comfort mode
If the room controller is set to Economy mode and the associated room unit is switched
to Auto (Comfort), the controller maintains Comfort mode for the period defined by the
temporary occupancy override time (veto) and then switches to Economy.This function
is only available if the room unit concerned has a
/
Auto switch (see also pages 41
and 52).

11.4 Presence detector switch-on and
switch-off delay
A switch-on or switch-off delay can be applied to the presence detector function. The
room controller only switches to Comfort or to Precomfort or Economy mode when the
delay time has expired.

11.5 Heating and cooling demand
To provide the required heating or cooling energy, the heating and/or cooling demand
from each room is transmitted to the building automation and control system.
Refer to the application example in section 3.4 for more detailed information on
heating/cooling demand.
In the case of changeover applications the real demand is transmitted, independent
from the state of the changeover input (therefore it might be that a controller demands
heat, if c/o = cooling and room temp < SpH).
With ETS Professional, this function can be disabled in the room controller.
This parameter is not supported.
