COMPACT Control System
Applies to COMPACT Air & Heat only
Electric Air Heater
The function is automatically activated when the TBLE
air heater is connected (standard in the COMPACT Heat
system).
On a heating load, the power supplied to the air heater is
controlled in sequence with the heat exchanger.
Whenever the air velocity through the unit is low, the
power supplied is automatically reduced to prevent the
electric heating elements from becoming overheated.
After the air heater has been in operation, the supply air
fan is always run for 3 minutes more for cooling the air
heater afterward. This occurs also if the air handling uit
has been manually switched off or automatic functions
have switched it off.
Applies to COMPACT Heat only
Manually Set Heating
Heating
Can be manually activated for increasing the temperature
in the room to be put to use. The controller controls the
unit’s air heater and airflow to meet the load (factory set-
ting: 45 minutes).
The function should be used only if the room is vacant
since the airflows and noise levels differ from the normal
ones.
Heating + Recirculation
Can be manually activated if very quick heating is de-
sired in the room to be put to use. The air handling unit’s
controller controls the air heater and airflow to meet the
load, the supply of outdoor air is shut off and room air is
circulated (factory setting: 45 minutes).
The function should be used only if the room is vacant
since the airflows and noise levels differ from the normal
ones.
Automatic Heating
The functions can be selected at Installation Level.
Intermittent Night-time Heating
The air handling unit is started and stopped within the
preset temperature limits for heating the room when it is
normally stopped by the time switch clock (timer).
The function is otherwise according to
Heating+Recirculation above.
Morning BOOST
The air handlng unit starts at the preset time, before the
start time of the time switch clock, with preset tempera-
ture setpoint for heating the room.
The function is otherwise according to
Heating+Recirculation above.
