RE additional heating elements are supplied to complete conventional water-
heating systems (e.g. ventilating convectors that work with a heat pump). They
may be used on the ventilating convectors from the éstro series, models 1 to 11.
This accessory cannot be used on the éstro FA wall model.
The kit is shown in figure 1. It is mainly composed of
A Armoured finned heating element made of aluminium, requiring a 230V / 1~
/ 50Hz power supply, pre-assembled with supporting brackets for fastening it
to the ventilating convector and equipped with automatic and manual reset
safety devices: the table below shows the power input (equivalent to the heating
capacity) and current absorption;
B An automatic-reset safety thermostat, integral with the heating element,
which switches it off should overheating occur;
C Safety fuse, mounted on the supporting brackets, which causes the heating
element to shut off in the event of a failure of the automatic-reset safety
thermostat.
D Brackets for supporting the heating element.
E Box containing electric wires and control relays.
F Set of intermediate heat-resistant plastic grilles.
G Additional fuse supports to be used for ventilating convectors with water
connections on the right.
H Package of screws.
I
Sticker with the warning "DO NOT COVER".
The RE heating element must be associated with one of the following controls:
These controls guarantee that the heating element will work safely, thanks to the
function of supplementing the hot water heating system and the post-ventilation
function
INSTALLATION
Warning! Before starting the installation procedure, disconnect the ventilating
convector from the power supply
1. Remove the cabinet covering the unit, where present, and replace the existing
intermediate grilles with the heat-resistant grilles supplied in the accessory
kit.
2. Remove the front panel from wall-mounted models and the condensation
tray from ceiling models.
3. Install the heating element complete with its supporting brackets on the
shoulders of the heat exchanger (4 fastening screws). The wires must come
out on the side opposite the water connections. Note: in the case of F3 -F4
ceiling-mounted ventilating convectors, replace the fuse with the one supplied
in the kit.
4. Pass the wires of the heating element and safety devices through the opening
provided on the side of the base unit; make sure you first thread the wires
through the bushing (figure 2, standard configuration with water connections
on the left).
If you are installing the heating element on a ventilating convector with water
connections on the right it will be necessary to change the position of the
safety devices (figure 3):
- the safety thermostat (B) must be installed on the front fin at the bottom,
always on the side where the wires come out;
- the fuse (C) must be installed using the new additional fuse support (G)
supplied with the kit and repositioned on the top part of the heating element,
on the side where the wires come out.

5. For éstro FL and FU floor-mounted ventilating convectors, install the
MICROPRO control panel (after configuring it by means of the internal
microswitches, see the manual provided) on the side of the base unit
opposite the water connections. Then fit the frame onto the control panel,
fasten the door with grille on the water connection side using the screws
provided, so as to prevent access to the heating element compartment.
The MICROPROD control panel (see the manual provided) must be fastened to
the wall in an easily accessible position allowing the user to set the functions
while ensuring an accurate reading of the ambient temperature. Therefore, avoid:
- positions directly exposed to sunlight;;
- positions exposed to direct currents of warm or cold air;
- placing obstacles that impede an accurate temperature reading (drapes or
furniture);
- constant presence of steam;
- covering the control panel or building it into the wall.
Install the MICROPROD in a position out of the reach of persons who are in the
bathtub or shower.
After installing the MICROPROD in the desired position, secure both doors of
the covering cabinet in place (using the screws supplied in the kit in the case of
FU and FL ventilating convectors); in the case of built-in ventilating convectors
(éstro FC series), prevent access to the heating element using grilles or ducts
that may be removed only with the aid of a tool.
6. Install box E containing the wiring and control relays on the same side of the
base unit as the control panel.
7. Make the electrical connections, with the power supply disconnected, strictly
complying with the wiring layouts shown in the MICROPRO-MICROPROD
manuals.
8. Fit the panel or condensation tray back in place.
9. Replace the cabinet (where present) and place the "DO NOT COVER" sticker
in proximity to the air outlet in a clearly visible position.
Each fan-coil requires a switch (IL) on the feeder line with a distance of at least
3 mm between the opening contacts, and a suitable safety fuse (F).
The minimum gauges of the power cables are specified in the table below:
To guarantee the efficiency of a ventilating convector unit equipped with a
supplementary RE heating element, comply with the following directions:
- On completing installation, make sure that the minimum airflow is guaranteed
(see table of "operating limits" below);
- Check the airflow rate periodically;
- Do not obstruct the air outlet or inlet of the ventilating convector in any way.
- Do not place damp or wet clothing on the air outlet grille of the ventilating
convector
- Do not turn off the ventilating convector using switch IL or by cutting off power
to the entire electric system. This would disable the post-ventilation function
and thus the air and components in the vicinity of the heating element would
risk overheating. Always use the MICROPRO/MICROPROD controls to switch
off the ventilating convector.
- Keep the air filter clean;
- Do not pour liquids inside the equipment.
HOW TO ORDER
N.B. If you are using accessory EYRE3 for ventilating convectors F3 and F4
mounted on the ceiling in a horizontal position (versions FU - FC), replace the
standard fuse (temperature 77°C) with the one supplied in the kit (temperature
98°C).
