With an outdoor temperature sensor con-

you can now set a fixed boiler temperature
setpoint.

V
keys to exit.

In the same way, set parameter 5 to "User" to set the
"reduced room temperature setpoint" or "reduced boi-
ler setpoint".
Parameter 555-b2 lets you specify whether a room
thermostat or a timer-thermostat is connected to the
"TA" terminals.
In the first case (room thermostat), the boiler switches
off when the contacts open.
In the second case (timer thermostat/room unit) the re-
ference curve will be that determined by the reduced
room temperature setpoint that has just been set.
