Checks After Installation; Cleaning - Beretta CONNECT AT LE Installer And User Manual

Selecting the heating MIN Set Point for the high temperature circuit
Access parameter 22 (MIN Set Point) and select the value chosen to suit the
needs and characteristics of the installation and the climatic curve set previously
(also see the boiler manual).
CONFIGURING THE LOW TEMPERATURE CIRCUIT
Access the parameters again using the password 53.
Activate the thermoregulation function on the low temperature circuit
Select parameter 46 (Thermoregulation function) and check that the factory setting
is 1 (AUTO).
If not, select the value 1.
Activate the climatic curve slope on the low temperature circuit
Access parameter 47 (slope on the climatic curve) and choose one of the curves
available as the climatic curve to be used for the high temperature system (see
graph) to suit the installation characteristics and the climatic conditions in the
geographical area (also see the boiler manual).
Selecting the heating MAX Set Point for the low temperature circuit
Access parameter 31 (MAX Set point) and select the value chosen to suit the
needs and characteristics of the installation and the climatic curve set previously
(also see the boiler manual).
Selecting the heating MIN Set Point for the low temperature circuit
Access parameter 32 (MIN Set point) and select the value chosen to suit the
needs and characteristics of the installation and the climatic curve set previously
(also see the boiler manual).
SETTING THE HEATING TEMPERATURE WHEN USING THERMOREGULA-
TION
If thermoregulation is active for the low temperature system, or if thermoregulation
is active for both the systems, the temperature value can be increased or decreased
compared to that calculated automatically by the board's electronics.
Alter the heating encoder. The correction factor can be chosen between comfort
levels -5 and +5.
SETTING THE HEATING TEMPERATURE WHEN THERMOREGULATION IS
EXCLUDED (FIXED POINT OPERATION)
If thermoregulation is not activated for either system, proceed as follows:
Selecting the Heating Set Point for the low temperature circuit
To select the Heating Set Point for the low temperature circuit alter the heating
encoder directly.
Selecting the Heating Set Point for the high temperature circuit
Use the password 00 (see the instructions in the boiler manual) to access the
programming parameters for the high temperature system.
Access parameter 0 (Heating Set Point) and select the value chosen to suit the
needs and characteristics of the installation. Also see the boiler manual.
EXCLUDING THERMOREGULATION FOR A SINGLE SYSTEM
It is possible to make only one of the two systems work without thermoregulation.
In this case, do not activate the thermoregulation function for the relevant circuit
(by altering parameter 44 for high and 46 for low), and select the fixed set point
for the relevant circuit.

CHECKS AFTER INSTALLATION

- Check that the heating system is pressurised.
- Check that the main switch for the plant works.
- Check the hydraulic circuits for leaks.
- Check that the hydraulic and electrical connections are correct.
- To call for heat from a mixed system, check that the mixing valve opens and
closes correctly.
If even one of these checks provides a negative result, the system must not be
started up.

CLEANING

Before cleaning the Connect AT/BT LE in any way disconnect the mains power
supply by switching the main switch to "OFF".
The panels must be cleaned with a cloth, using soap and water.
If stubborn stains are found, use a cloth with a 50% water and denatured alcohol
mixture, or use specific products.
Once cleaning is complete, dry carefully.
Do not use abrasive products, benzene, or trichloroethylene.
