REMKO MXD 202 - Manual (Page 9)

3 Design and function
3.1 Equipment description
The indoor unit serves to extract heat from the
indoor room being cooled. The outdoor unit then
expels this heat to the outside.
If combined heating/cooling units are operated as
heaters, the heat absorbed by the outdoor unit can
be discharged by the indoor unit into the room
being heated.
The unit series has priority "heating", this means
that units that are in heating or automatic mode,
other units in the system that are in cooling mode
can switch off.
The unit is designed for installation high up on
indoor walls.
Operation takes place using an infrared remote
control.
The indoor unit consists of a fin vaporiser, vapor-
iser fan, controller and condensation pan.
The indoor unit can be combined with REMKO out-
door units of series MVT 601DC, 901DC und
1051DC with sufficient combinations. The outdoor
component is controlled via the controller of the
indoor unit.
Cabled remote control and condensation pump are
available as an accessory.
