reduced physical, sensory or mental capabilities
or lack of experience and knowledge if they have
been given supervision or instruction concerning
use of the appliance in a safe way and
understand the hazards involved. Children shall
not play with the appliance. Cleaning and user
maintenance shall not be made by children
without supervision.
CAUTION
1. Turn off the domestic cold water inlet.
2. Open a hot water tap on the installation.

4. When the water stops flowing, the appliance
has been drained.
1. Safety instructions 200SE-2S - 300SE-2S
626/04/2016 - 7607575-05

CAUTION
Pressure limiter device
4The pressure limiter device (safety valve or
safety unit) must be operated regularly in
order to clear out any limescale deposits and
ensure that it is not blocked.
4The pressure limiter device must be
connected to a discharge pipe.
4As water may flow from the discharge pipe,
it must be kept open to the air, in a frost-free
environment, in a continuous downward
gradient.
For the type, characteristics and connection of
the pressure limiter device, please refer to the
section entitled Connecting the domestic hot
water tank to the drinking water network in the
installation and service manual for the domestic
hot water tank.
The user guide and the installation manual can
also be found on our internet site.
CAUTION
Allowance must be made for a means of
disconnection in the fixed pipes in accordance
with the regulations on installations.
CAUTION
If a power cord is provided with the appliance
and it turns out to be damaged, it must be
replaced by the manufacturer, its after sales
service or persons with similar qualifications in
order to obviate any danger.
200SE-2S - 300SE-2S 1. Safety instructions
26/04/2016 - 7607575-05 7

CAUTION
Respect the maximum water inlet pressure to
ensure correct operation of the appliance,
referring to the chapter "Technical
Specifications".
CAUTION
Before any work, switch off the mains supply to
the appliance.
CAUTION
In order to limit the risk of being scalded, the
installation of a thermostatic mixing valve on the
domestic hot water flow piping is compulsory.
1.2 Recommendations
CAUTION
Do not neglect to service the appliance. Service
the appliance regularly to ensure that it operates
correctly.
WARNING
Only qualified professionals are authorised to
work on the appliance and the installation.
WARNING
4The heating water and the water-propylene-
glycol mixture must not come into contact
with the domestic hot water.
4The domestic hot water must not circulate
through an exchanger.
4Solar installations can be protected against
lighting and must be earthed or connected
to an equipotential connection.
To take advantage of the guarantee, no modifications
must be made to the appliance. Only remove the covers
for maintenance and breakdown repair operations and put
the covers back in place after the maintenance and
breakdown repair operations.
Instructions stickers
1. Safety instructions 200SE-2S - 300SE-2S
826/04/2016 - 7607575-05

The instructions and warnings affixed to the appliance
must never be removed or covered and must remain
legible during the entire lifespan of the appliance.
Immediately replace damaged or illegible instructions and
warning stickers.
WARNING
Never cut the power to the solar control system,
even during extended absences. The control
system protects the installation against
overheating in summer when it is running.
WARNING
Do not modify the control system parameters
unless fully conversant with them.
During extended absences, we recommend lowering the
set point temperature in the solar DHW calorifier to 45°C.
When the user is present, the set point must be set to
60°C.

3.2 General description
200SE-2S - 300SE-2S domestic hot water calorifiers are connected
to solar collectors by a solar station.
The calorifiers 200SE-2S - 300SE-2S are fully equipped with a solar
technical station, consisting of a charge device for each zone, a safety
device, an expansion vessel, a pump, a solar control system Delta
Sol AEL etc.
Main parts:
4The tanks are made of high quality steel lined with food quality
standard enamel vitrified at 850°C, which protects the tank from
corrosion.
4The heat exchangers welded into the tank are made of smooth
piping, the external surface of which, in contact with the drinking
water, is enamelled.
4The appliance is highly insulated with CFC-free polyurethane
foam, which reduces thermal losses to a minimum.
4The external casing is made of ABS.
4The tanks are protected against corrosion by several magnesium
anodes.

Live Operating description
1The sun’s irradiation heat the transfer fluid in the collector. To trigger the circulation pump, a minimum temperature of
30°C is necessary in the collectors (CMIN) as is a temperature difference of 6 K between the temperature of the collectors
and the DHW tank.
2In the automatic calibration phase (setting parameter tu, factory setting 3 minutes), the solar pump (relay 1) operates on
full (100%) in order to stabilise the temperature in the solar circuit.
3Subsequently, the rate at which the solar pump operates is calculated dynamically to maintain a reference temperature
difference (parameter DT, factory setting 20 K) between the collectors and the DHW tank.
4The system loads the DHW tank according to the heat available in the collectors and stops when the set point temperature
of the DHW tank is reached (setting parameter SX, factory setting 60).

Live Operating description
5When the temperature in the collectors reaches the maximum value (adjustment parameter CMAX, factory setting 110°C),
the solar pump is triggered to cool the collectors.
The pump continues to operate until the temperature in the collectors is lower than 5 K at parameter CMAX and/or the
maximum storage temperature (80°C) is reached in the hot water storage tank.
6When there is less available sunlight, the temperature in the collectors drops and the temperature in the DHW tank is
stable.
7As soon as the temperature in the collectors drops below the temperature in the calorifier, the calorifier is cooled down to
its set temperature.
8When the set point SX is reached, the circulation pump shuts down, the temperature in the collectors drops again and the
temperature in the DHW tank falls according to any draw-offs made.
The DHW tank cooling function is inactive if using tubular
collectors (function FT active).
3.4.2. Protection against overheating on the solar
circuit
The control system has various functions, which are easy to discern
for the user, which limit overheating of the installation’s components.
