1. GENERAL INFORMATION
1.1 Warnings
This product has been manufactured according to rigorous technical rules of safety in conformity with EC
standards. The EC declaration may be downloaded from the Internet site (address given on the last page).
Before installing and using this product, carefully read these instructions, which contain important indi-
cations for your safety and the user’s safety during the installation, commissioning and maintenance of
this product. Once the installation is terminated, keep this manual handy nearby the machine for future
consultation.
This product must be installed (installation, connections, commissioning, maintenance) and all other inter-
ventions performed by a professional applying recognized good practice procedures, and respecting the
standards and safety regulations in force. The installation must be made in accordance with the prescrip-
tions indicated in the Electromagnetic Compatibility (EMC) and Low Voltage (LV) Directives.
We advise all people exposed to risks to scrupulously respect the accident prevention standards. The ma-
nufacturer may not be held liable for any human injury and/or material damage resulting from the non-res-
pect of the safety instructions or from a change made on the product.
JBRB ECOWATT®PR units are intended for controlled mechanical ventilation or air recycling applications
on tertiary premises and in collective residential buildings:
• Indoor or outdoor installation
• Environmental temperature: -20°C / +50°C
• Relative humidity: max. 95% without condensation
• Non-potentially-explosive atmosphere

1.2 Safety instructions
• Put on appropriate PPE (Personal Protective Equipment) before any work.
• Before installing the ventilation unit, make sure that the bracket and the location are strong enough
to bear the weight of the unit and any accessories.
• Do not open the access panels without having shut o󰀨 the padlockable switch-disconnector included
in the unit.
• If work has to be carried out on the device, cut o󰀨 the power supply on the main circuit breaker and
make sure that nobody can accidentally turn it back on.
• Make sure that moving parts are stationary.
• Check that the ventilation motor is not accessible via the connection brackets. (connection sheath
or protective shield).
Before starting, check the following points:
• Make sure that the device does not contain any foreign bodies.
• Check that all the components are mounted in their original positions.
• Check manually that the fans do not rub or get blocked.
• Check the connection of the earth electrode.
• Check that the access hatch is properly closed.
1.3 Reception - Storage
In case of short shipment, non-conformity, and/or total or partial damage to the products delivered, the
Buyer must, in accordance with article 133-3 of the French Commercial Code, add written reservations to
the carrier’s delivery slip and conrm them within 72 hours by registered letter with acknowledgement of
receipt with a duplicate for the seller. If the equipment is received without express reservation, the Buyer
has no subsequent recourse against us.
The product must be stored protected from weather, shocks and soiling due to splashing of any kind during
its transport from the supplier to the nal customer and on the site before installation.

4/48 NT00000603-JBRB-ECOWATT-PR-AN-191202
1.4 Warranty
The equipment is covered by a 12-month parts-only warranty from the billing date.
The seller undertakes to replace all parts or equipment that it recognises as malfunctioning, to the exclu-
sion of any damages or penalties such as operating losses, market injury and other non-material or indirect
damage.
The following are excluded from our warranty: faults connected with abnormal use or use not in accord-
ance with the recommendations in our manuals and instructions, defects found following normal wear and
tear, incidents caused by negligence, failure to monitor or maintain correctly, defects due to poor installa-
tion of the equipment or to poor storage conditions before installation.
In any event, the seller is not responsible for equipment that has been modied or repaired even if only
partially.

Comment:
JBRB ECOWATT®PR models are equipped with an electronic-switching motor.
This motor is protected by:
- a built-in thermal protection on the motor winding,
- a thermistor built into the electronics.
These built-in motor protection systems have been tested and approved during re-resistance testing and
certied C4 400°C 1/2hr.

Operating modes
COP mode: Constant pressure control
This operating mode is used to maintain constant pressure in the network over the fan’s entire used oper-
ating range. Network pressure drops (register opening/closing, dual-ow vents, etc.) modify the pressure
in the ventilation unit inlet plenum.
This pressure is measured by a sensor built into the RMEC controller.
This pressure measurement combined with a control loop means the RMEC can adjust fan speed to main-
tain constant pressure in the network.
The pressure setting can be adjusted using the RMEC controller control buttons.
Its operates 100%-automatically.
This operating mode is programmed by default on the unit when it leaves the factory with a pressure set
point of 140Pa.

CAV mode: Constant air volume control
This operating mode is used to maintain constant airow in spite of changing network pressure drops (ex-
terior screen clogging, etc.). Up to 2 constant airow settings can be entered.
When CAV mode is selected, it is programmed to operate at a factory-pre-set airow of 70% of max. air-
ow. (See table § "6.9 CAV: Constant airow – 1 setting", page 28)
This value can be modied. Up to 2 airow set points can be entered, and in this case, a BCCA 2V 3-po-
sition switch will have to be used to switch from one airow to another. (See diagram § "5.4 Electrical
connection of an external On / O󰀨 control", page 17)

VAV mode: Variable airow control according to analogue input
In VAV mode, the airow varies linearly, according to a setting signal (voltage 0-10V or current 4-20mA),
between a min. airow and a max. airow to be set in the RMEC controller. Each signal value corresponds
to an airow maintained constant irrespective of network pressure drops.

The signal can be transmitted by di󰀨erent types of sensors:
• SCO2 – CO2 sensor (0-10V or 4-20mA), in this case it will be displayed in ppm
• SHUR – Hygrometry sensor (0-10V or 4-20mA), in this case it will be displayed as a %
• STEM – Temperature sensor (0-10V or 4-20mA), in this case it will be displayed in °C
Or by a potentiometer:
• CVF
• REB ECOWATT®
The airow can be varied over part of the sensor’s measurement range or part of the potentiometer’s
voltage range (see § "6.11 VAV: Sensor-type analogue input airow control", page 30 and § "6.12 VAV :
Potentiometer-type analogue input airow control", page 34).
