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.

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.
A valve assembly, 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 for use 
indoors in the lower wall area 
(vertical installation) and for ceiling 
installation (horizontal installation). 
Operation is either individually 
or in groups using a room 
temperature controller or via 
the building management system.
The unit consists of a fin heat 
exchanger, circulation fan, 
controller and two condensate 
trays for horizontal and vertical 
installation.

The available accessories 
include room temperature 
controllers for installation in 
the unit or on the wall, heating 
coil for connection to a 4-wire 
system, valve assembly cooling, 
fan modules, air inlet plinth, 
duct parts, grille and condensate 
pumps.

Intended use

Depending on the model and 
the equipment, the units are only 
intended to be used as a cold 
water drain to cool or warm 
the operating medium water 
or a water-glycol mixture within 
a closed medium cycle.
Any different or additional 
use is a non-intended use. 
The manufacturer / supplier 
assumes no liability for damages 
arising from non-intended use. 
The user bears the sole risk in such 
cases.
Using the equipment as 
intended also includes working 
in accordance with the operating 
manual and installation 
instructions and complying with 
the maintenance requirements.
