9.2.5 Morning BOOST
(applies to COMPACT Heat only)
The unit is utilised to heat the premises during a preset
period prior to the switch-in time set on the switch clock.
The unit starts early and uses the separate settings for
operation and temperature regulation.
The preset time is the time difference between the start of
Morning BOOST to the start of ordinary operation.
Damper output can be set to be inactive. This means that
connected dampers (e.g. outdoor air and exhaust air shut-
off dampers) are not affected. Normally these dampers
are closed when the unit is stopped and thus they remain
closed. The damper in the air recirculation section opens
at the same time.
The extract airflow can be set to Inactive
if it is not desir-
able for the extract air fan to operate.

9.2.6 Setpoint Temperature Displacement
Used for changing the supply air and extract air tempera-
ture setpoints by means of an external 0-10 VDC signal
(control unit terminals 35 (-), 37 (+)). The temperature can
be increased or decreased at certain times of the day by
means of an external switch clock or potentiometer, for
instance.
The setpoint can be influenced ±5 °C.
If the unit is operating in the supply air regulation mode,
the supply air temperature is displaced and if the unit is
operating in the extract air regulation mode, the extract
air temperature is displaced.
When the unit is operating in the ERS regulation 1 mode,
the difference between extract air and supply air is influ-
enced. The difference cannot be less than 0 °C. The differ-
ence will decrease as the input signal increases.
If the unit is operating in the ERS regulation 2 mode, the
supply air setpoint will be offset.
When the function is activated, the setpoint is offset as
illustrated in the chart to the right.

Control signal V DC
Setpoint temp displacement involves:
Control signal 0 V DC: The setpoint is lowered by 5 °C.
Control signal 5 V DC: Unchanged setpoint.
Control signal 10 V DC: The setpoint is increased by 5 °C.
