IMPORTANT SAFEGUARDS AND WARNINGS
WARNING: FIRE AND SHOCK HAZARD
nVent RAYCHEM HWAT Systems must be installed correctly to ensure proper
operation and to prevent shock and re. Read these important warn ings and carefully
follow all the installation instructions.
To minimize the danger of re from sustained electrical arcing if the heating cable
is damaged or improperly installed, and to comply with nVent requirements, agency
certica tions, and national electrical codes, ground-fault equipment protec tion has
been built into the HWAT-ECO-GF controller and must be used on each heating cable
branch circuit. Arcing may not be stopped by conventional circuit breakers. Approvals
and performance are based on the use of nVent parts only. Do not substitute parts
or use vinyl electrical tape. Bus wires will short if they contact each other. Keep bus
wires separated.
Connection kits and heating cable ends must be kept dry before and during
installation. The black heating cable core is conductive and can short.
They must be properly insulated and kept dry.
Damaged bus wires can overheat or short. Do not break bus wire strands when
preparing the cable for connection. Damaged heating cable can cause electrical
arcing or re. Do not use metal attachments such as pipe straps or tie wire. Use only
nVent approved tapes and cable ties to secure the cable to the pipe.
Do not attempt to repair or energize damaged cable. Remove damaged cable at once
and replace with a new length using the nVent RAYCHEM RayClic-S splice kit. Replace
damaged connection kits. Use only re-resistant insulation which is compatible with
the application and the maximum exposure temperature of the system to be traced.
MISES EN GARDE ET AVERTISSEMENTS IMPORTANTS
AVERTISSEMENT: RISQUES D'INCENDIE ET DE CHOCS
Les systèmes nVent RAYCHEM HWAT doivent être installés correctement pour
assurer un fonctionnement approprié et pour éviter les risques d'incendie ou de
chocs électriques. Lisez attentivement les mises en garde suivantes et suivez les
instructions d'installation.
Pour minimiser le danger d'incendie causé par un arc électrique entretenu, si le câble
chauffant est endommagé ou mal installé, et pour respecter les exigences de nVent,
des organismes d'homologation et celles du code national de l'électricité, il est
impératif d'utiliser une protection par disjoncteur différentiel sur chaque régulateur
HWAT-ECO-GF et sur chaque circuit alimentant un câble chauffant. Un disjoncteur
ordinaire peut ne pas être assez sensible pour prévenir les arcs continus. Les
homologations et le rendement reposent uniquement sur le recours à des pièces
nVent. Ne substituez pas de pièces ou n’utilisez pas de ruban électrique en vinyle.
Les ls omnibus peuvent être court-circuités s’ils se touchent. Tenez les ls omnibus
éloignés les uns des autres.
Les trousses de connexion et les terminaisons des câbles chauffants doivent être
tenues au sec avant et pendant l’installation. Le noyau du câble chauffant noir est
conducteur et peut occasionner des court-circuits. Il est nécessaire d’isoler
adéquatement les câbles et de les tenir au sec.
Les ls omnibus endommagés peuvent surchauffer et occasionner des court-circuits.
Portez attention pour ne pas casser les brins du l omnibus lors de la préparation du
câble aux ns de raccordement. Un câble chauffant endommagé peut provoquer des
chocs électriques, des arcs et des incendies. N'utilisez pas de pièces de xation
métalliques, par exemple des courroies ou des ls d’attache. N’utilisez que des
rubans et des attaches approuvés par nVent pour attacher le câble au tuyau.
N'essayez pas de réparer ni de brancher un câble chauffant endommagé.
Retirez-le immédiatement et remplacez-le par un neuf à l’aide de la trousse d’épissure
nVent RAYCHEM RayClic-S. Remplacez les trousses de connexion endommagées.
N’utilisez qu’un isolant ignifuge compatible avec l’application et avec la température
d’exposition maximale du système à installer.
WARNING: Water temperature above
130°F (55°C) presents a significant risk of
personal injury and/or death and requires
that scald protection measures be
implemented for safe use.
AVERTISSEMENT : température de l’eau supérieure
à 55 ° C (130 ° F) présente un risque important de
blessure et / ou de mort, et impose que des mesures
de protection contre l’échaudure soient mises en place
pour une utilisation en toute sécurité.

3. INSTALLATION NOTES
3.1. Use of the Manual
This manual covers the installation and operation of the nVent RAYCHEM
HWAT-ECO-GF controller and must be used with the following additional documents:
HWAT System Product and Selection Design Guide (H57538) HWAT System Installa-
tion and Operation Manual (H57548).
IMPORTANT: For the nVent warranty and agency approvals to apply, the instruc tions
included in this manual and product packages must be followed.
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-GF 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.
Pre-Installation testing
Prior to installing the HWAT-ECO-GF controller, perform the insulation resistance
(Megger) test and circuit length verication (Capacitance) test on the heating cable
as detailed in the HWAT System Installation and Operation Manual (H57548).
Installing the controller
Install the controller in an indoor, dry, clean, acces sible location. If using the optional
pipe temperature sensor, make sure you install the controller within 328 ft (100 m) of
where you want to monitor the pipe temperature.
Opening the controller
WARNING: To prevent shock, always switch off the power supply (circuit breaker)
before opening the controller.
The HWAT-ECO-GF has a removable front cover. Both the cover and the box have
electronic parts and are connected to each other by an Ethernet cable. First unscrew
the four screws in the cover.
3.2. Description
The HWAT-ECO-GF control unit has been developed for operation with the
self-regulating heating cables: nVent RAYCHEM HWAT-R2.
The hot water temperature maintenance system is a comfort system providing
instant hot water at the tap. A self-regulating heating cable is positioned on the pipe
and compensates for any temperature loss of the warm water.
The HWAT-ECO-GF control 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 larger and more complex domestic hot water systems, the HWAT-ECO-GF
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 networks.
• 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.
• Built-in ground fault protection

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-GF 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 full hygienic requirements and
avoid energy waste.
Boiler high

limit
You can determine the high temperature limit.
If this value is reached the unit will switch off
the heating system to avoid scalding.

temperature. The economy temperature is the water
temperature for periods in which the amount of hot water
used is low (at night) or high (peak period). Select the
temperature using the + / - keys. The minimum
temperature is 98°F/37°C for use in environments such as
schools, and 105°F/41°C in the Apartments program.
The maximum temperature is the selected maintain
