3. INSTALLATION NOTES
The installation and, if necessary, the maintenance and the
disassembling must be carried out by a qualified electrical installer.
The installation must be compatible with local regulations. Check the
maximum circuit length for your circuit breaker in the next table:
Maximum circuit length at VAC and for °C start-up temperature
C-characteristic circuit breaker
Multiple units on multiple power points can be used if longer heating
cables are required. We recommend to use nVent RAYCHEM HWAT-SBS
panels to operate 3, 6, 9or 12 heating circuit

The nVent RAYCHEM HWAT-ECO has a removable top lid. Both top and
bottom of the box have electronic parts and are connected to each other
by an Ethernet connector cable. The unit is delivered with top lid and
back part dismantled.
Warning: For over voltage protection (e.g. in case of thunderstorm) we
recommend the use of an external over voltage protection device.
Care and maintenance
Clean the HWAT-ECO with a soft damp cloth only, do not use any
solvents. Do not pour water directly on the device. Do not use a water
hose or a high pressure cleaner.
Description
The HWAT-ECO control unit has been developed for operation with the
self-regulating heating cables: nVent RAYCHEM HWAT-R, HWAT-M and
HWAT-L. The hot water temperature maintenance system is a comfort
system providing instant hot water at the tap. A self-regulatinga heating
cable is positioned on the pipe and compensates for any temperature
loss of the warm water.
The HWAT-ECO control unit combines the following features:
• The operating temperature of the heating cable can be limited to a
desired temperature. Combined with the integrated “power off” timer
function, this offers important energy savings.
• Energy can be saved upon activation of the “trace boiler” function
and installation of the boiler sensor. The maintain temperature of
the heating cable will automatically be lowered in case the boiler
temperature is reduced, preventing the heating cable from using too
much energy for heating the water in the pipes.
• On big warm water systems it is sufficient to programme one
HWAT-ECO unit in a nVent RAYCHEM SBS panel to manage multiple
heating circuits. The HWAT-ECO controller can be delivered in
different prefabricated panels, depending on the quantity of heating
circuits (3, 6, 9).
• An alarm terminal makes remote reading of errors possible.
• A pipe sensor (to be ordered separately) can be installed as reference
point to track and monitor pipe temperature in a large hot water
distribution network.
• The unit can be pre-programmed in power-off mode by external
power bank (to be ordered separately) connected via A-A-USB cable
and USB connection.

4. OPERATION
The HWAT-ECO version 5has a resistive touchscreen user interface:
The unit will go in dim mode after 2minutes with no interaction.
The unit will switch to the main screen after 2minutes of no-interaction
on the parameter input screens.
Quick install
When the unit is powered up for the first time, a quick setup must be
executed before the unit is ready to start. The Quick start helps to set all
important settings, the unit will go in main screen mode automatically
when done. Quick start is sufficient for normal operations. More settings
are available in the Setup menu for special installation conditions.

parameters
Every parameter line shows the actual value /attribute for
each parameter.
HWAT cable Select the type of cable used in your installation
(HWAT-L, HWAT-M, HWAT-R).
Pipe
diameter
Set the pipe diameter. You can change the value from DN
15 mm up to DN 125.
Insulation
thickness
Set the insulation thickness. You can change the value
from 9to 130 mm, with the pipe diameter as the limiting
value.
Boiler sensor
Activate/deactivate a connected boiler sensor by clicking
on ON/OFF. The external temperature sensor measures
the boiler temperature. The trace boiler setting is
included to ensure that the heating cable temperature
does not exceed the boiler temperature. The HWAT-ECO
memorizes the highest measured temperature over
the last 24 hours. If the boiler temperature is too low,
the maximum temperature is lowered to the boiler
temperature minus the trace temperature. In this case
the green trace boiler LED will be on.
Boiler low
temperature
limit
You can determine the low temperature limit. If the
boiler temperature reaches this value, the unit will
switch off the heating system in order to fulfil hygienic
requirements and avoid energy waste.
Boiler high
temperature
limit
You can determine the high temperature limit.
If this value is reached the unit will switch off
the heating system to avoid scalding.
Pipe sensor
Activate/deactivate a connected pipe sensor by pressing
ON/OFF. The pipe sensor monitors the pipe temperature
and needs to be installed close to the furthest point in
the pipe distribution network.
Pipe sensor
low

limit
You can determine the low temperature limit.
When the value is reached a warning will appear on the
screen but will not interrupt the unit’s functioning. The
info status screen will show the actual pipe temperature.
Pipe sensor

limit
You can determine the high temperature limit. A warning
will appear on the screen when the value is reached but
