Guarantee

As a prerequisite for any guarantee 
claims to be considered,  
it is essential that the ordering 
party or its representative  
complete and return  
the "certificate of warranty"  
to REMKO GmbH & Co. KG  
at the time when the units are 
purchased and commissioned.
The guarantee conditions are  
listed in the "General terms  
and conditions". Furthermore, 
only the parties to a contract 
can conclude special agreements 
beyond these conditions. In this 
case, contact your contractual 
partner in the first instance.

(energy is given up) or past  
the resister (energy is not given up). 
The unit is designed for installation 
in suspended ceilings (horizontal 
installation), in an indoor area. 

Thanks to the new and very robust 
brushless EC fans (electronically 
commutated), the energy 
consumption, particularly  
in the low speed range, can be 
reduced significantly and the fan 
speed can be adjusted infinitely  
to the requirements. This also 
enables an infinitely variable 
output of the cooling or heating 
capacity in order to obtain an even 
more constant temperature  
in the room.
The unit can be operated via 
numerous controller options  
or via an external control signal. 
The applications can be adjusted 
easily using jumpers. The following 
controls are possible:

■ 

Single control 

using the IR remote 

control provided by the factory, 
alternative cabled remote control 
(accessory) with five-stage fan 
operation

■ 

Network control f

or up to 

32 units, 

all units within 

a group via a REMKO bus 
provided by the factory  
with five-stage fan operation

■ 

Network control f

or up to 

32 units, 

specific units within 

a group via a REMKO bus 
provided by the factory  
with five-stage fan operation

■ 

Single control

room temperature

 controller 

(provided 

by the customer 

or available as an accessory) 
with three-stage fan operation

■ 

Group control 

using the wired 

room temperature

 controller 

and switching relay (provided 

by the customer or available  
as an accessory) with three-
stage fan operation

■ 

Single control 

via external 

0 - 5V or 0 - 10V signal

 

(e.g. CBCS) with infinitely 
variable fan operation

■ 

Modbus network control 
via 

external hardware

 or CBCS

 

with infinitely variable fan 
operation

The unit comprises a fin register, 
an EC recirculating fan,  
a condensate tray with  
a condensate pump, an additional 
condensate tray for the valve 
assembly, swing fins, controller 
with IR remote control and shape 
improver, a discrete cover  
for horizontal installation within 
suspended ceilings.
The controller enables  
the air quantity to be reduced  
or increased by adjusting  
the jumpers. This can also be  
done retroactively and is used  
to be able to react to changes  
to the room's use. A potential-free 
input for the "Enabling contact" 
and an output for "Operating 
modes" and "Cooling/heating 
request" are available.

The accessories available include 
room temperature controllers  
for installation in the unit  
or on the wall, a cooling valve 
assembly and condensate pumps.

Unit description

 

In cooling mode the unit (chilled 
water outlet) extracts the heat 
from the interior room to be 
cooled into the fin register  
and passes it on to the cold 
operating medium - water  
or a mix 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 warms  
the room to be heated.  
The medium cools down as a result 
of the heat exchange.
To control the cooling or heating 
capacity, a valve assembly  
that is available as an accessory is 
used, which routes the operating 
medium through the register
