Each discipline has its own rules for determining the influence of energy
efficiency that is evaluated in the room coordination function.
The criteria for evaluating energy efficiency are:
● The maximum tolerance to manually shift the room temperature setpoint
can be configured.

● Fan speed: No configuration. A higher value than the automatic value is
classified as inefficient.
● Room operating mode: No configuration. A higher value than the automatic
value is classified as inefficient.
● Lighting: No configuration. Lighting setpoints cannot be less energy
efficient than the automatic values.
● Shading: No configuration. Shading positions cannot be less energy efficient
than the automatic values.
The application tracks the heating/cooling state of the room as well as average
room temperature over 24 hours and notes the Comfort room temperature
setpoints for heating and cooling. And decides, based on the present comfort
setpoints for cooling and heating, the room temperature and heating/cooling
state whether shading supports heating and cooling. The information is
provided to the local shading elements in the room and processed as per the
settings.
The application outputs the thermal room load condition with two states: Load
(heating) and discharge (cooling).
Manual operation on all room operator units for HVAC can be locked based on
the specified central operating mode. Manual operation for lighting and blinds
is always available and is not impacted by this function.
A parameter determines if manual operation can be locked for HVAC. Manual
HVAC operation is locked during the displayed room operating modes, i.e.
Comfort cannot be increased and energy efficiency cannot be changed.
