1.3.1 Applications
The Comfort Circle is designed for heating, cooling and/or
ventilating rooms.
The model is designed for integration into suspended ceilings
but can be used in other ceilings as well. The unit is designed
to be mounted at a height of 2.0 to 3.5 m (from floor to dis-
charge grille).
The recirculation unit draws air from the room, heats or cools
it, and blows it back into the room.
The ventilation unit draws air from elsewhere, heats it, and
blows it into the room. This may be either unconditioned out-
side air or preconditioned air supplied by an A/C system. The
ventilation unit is available in two models: air intake from a
side, and air intake from above.
1.3.2 Working
The Comfort Circle blows out a flow of heated or cooled air,
creating a comfortable climate in the room.
The units that can both heat and cool have automatic dis-
charge angle control, which determines the discharge angle
based on the mode (cooling or heating). The other units have
a fixed discharge angle setting.
The units that can cool come standard with an integrated con-
densate draining pump.
The unit can be delivered with two types of control: a modu-
lating control and an On/Off control. The modulating control
controls both the fan speed and the discharge temperature to
reach the desired room temperature. The On/Off control
controls only the fan speed to achieve this goal. The ventila-
tion units come with modulating control only.
