n Heating curve with BCT
The BCT (Base heat Curve Temperature) parameter allows a
minimum operating temperature to be imposed on the heating circuit
(this temperature may be constant if the circuit gradient is nil).

1. Remove the measuring equipment.
2. Put the flue gas sampling plug back in place.
3. Refit the front panel. Tighten the two screws by a quarter turn.
4. Raise the temperature in the heating system to approximately
70°C.
5. Shut down the boiler.
6. After about 10 minutes, vent the air in the heating system.
7. Checking the hydraulic pressure. If necessary, top up the water
level in the heating system (recommended hydraulic pressure
T001522-A
between 1,5 and 2 bar).
8. Tick the gas category used on the data plate.
9. Complete the checklist.
10.Explain the operation of the installation, the boiler and the
regulator to the users.
11.Inform the user of the periodicity of maintenance work to be carried
out. Input the service date and the contact details of the installer.
¼ See chapter: "Customising maintenance", page 95.
12.Give all the instruction manuals to the user.
Commissioning of the boiler is now complete.
Maximum temperature of the circuit
Water temperature in the circuit for an outside
temperature of 0°C
DAY set point on the circuit
Outside temperature for which the maximum water
temperature in the circuit is reached
Value of the heating curve
Select the parameter CIRC. CURVE ...
Value set to the parameter HCZP D
When you modify the heating curve, Z and R are
recalculated and repositioned automatically.
Finalizing work
The various boiler parameters are preset in the factory.
These factory settings are suitable for the most common
heating systems. For other systems and situations, the
parameters can be modified.
