REMKO WLT 25 - Manual (Page 6)

Infrared remote control
The infrared remote control
sends the programmed settings
a distance of up to 6 m to the
receiver of the unit (fig. 1, page 7).
Data will only be received correctly
if the remote control is pointed
at the receiver and no objects are
obstructing the transmission path.
First insert the supplied batteries (2
each, type AAA) into the remote
control. To do so, pull off the flap
of the battery compartment and
insert the batteries correctly by
polarization (see marks).
Operation
The unit is easily operated using
the standard infrared remote
control. The unit beeps to
acknowledge the correct
transmission of data. If it is not
possible to program the indoor unit
with the remote control, then it can
also be manually operated.
Manual operation
The unit can also be started
manually. After the air inlet screen
has been opened, the inner
recessed key can be pressed and
automatic mode can be activated.
Press a key on the infrared remote
control to interrupt the manual
operation.
Display
The lit display LEDs indicate the
mode set.

Cooling
Immediately replace flat
batteries with a new set,
otherwise there is a risk of
leakage. It is recommended
that the batteries are removed
if the equipment is shut down
for longer periods.
NOTE
Unit description
In cooling mode the unit (chilled
water user) extracts the heat from
the interior room by the finned
heat exchanger and transform it to
the cold operating medium water,
or a mixture of water and glycol,
within a closed medium cycle.
As a result of the heat exchange
the medium heats up and the
emergent air cools the room down.
In heating mode a warm operating
medium is able to warm up the
room. The medium cools down as
a result of the heat exchange.
A 3-way-valve, which routes
the operating medium through
the register (energy is given up)
or past the resister (energy is
not given up), is used to control
the cooling or heating capacity.
The unit is designed to be
mounted high up on indoor
walls. It is operated by an infrared
remote control.
The unit consists of a finned
heat exchenger, circulation fan,
controller and condensate pan.
Cabled remote controls and
condensate pumps are available as
accessories.
