12. Installer settings

` BCT (Bottom of Curve temperature)

Used to impose a minimum temperature on the boiler circuit.

To direct/control the boiler at a constant temperature by HCZP,

set circuit gradient A/B to 0. This setting is required to control an

aerothermal or pool type circuit.

For example: A different value may be set for day time HCZP D

or night time HCZP N between the values NO, 20 to 90ºC.

` MAX.CIRC...

For circuits B and C, this setting limits the start temperature in the

corresponding circuit.



If using underfloor heating, do not modify the factory

setting (50 °C).

Regulations require a safety system independent of the

control unit, with manual reset, which cuts the heat supply

to the underfloor heating when the temperature of the fluid

reaches 65°C (France: DTU 65.14).

Connect a safety thermostat to the TS contact on the pump

connector.

It is advisable to set the RELATIVE DHW parameter in the

event of domestic hot water production.

` FL.DRY...

Used to impose a constant outlet temperature to accelerate

drying of an underfloor heating floor.

The setting of this temperature must follow the

recommendations from the underfloor heating installer.

The activation of this parameter (setting other than NO) forces

the permanent display of FL.DRY C and deactivates all other

functions on the control unit.

When floor drying is active on a circuit, all other circuits (e.g.

DHW) are shut down. The use of this function is only possible on

one circuit.

` OUT.ANTIFREEZE

Below this temperature the pumps are permanently on and the

minimum temperatures for each circuit are respected.

When NIGHT : STOP is set, the reduced temperature is

maintained in each circuit.
