HYST OFF LOW TEMP
For low temperature systems, this parameter allows you to set the hysteresis value used by the

SCREED HEATING
This parameter allows you to activate the screed heater function (see paragraph "4.15 Screed
heating function" for more details). The factory setting is 0, with the boiler set to OFF, set to 1 to
activate the screed heater function on the low temperature heating zones.
The parameter automatically returns to 0 once the screed heater function is finished, it is possible to
interrupt it earlier by setting the value to 0.
ANTI CYCLE FUNCTION
This parameter allows you to change the FORCED HEATING TIMING OFF, regarding the delay
time introduced for re-igniting the burner in the face of an off due to the heating temperature being
reached. The factory setting for this parameter is 3 minutes and can be set to a value between 0
min and 20 min.
RESET CH TIMERS
This parameter allows you to cancel the ANTI CYCLE and REDUCED HEATING MAXIMUM
OUTPUT TIMING, lasting 15 min during which the speed of the fan is limited to 75% of the maximum
heating output that has been set.
The factory setting for this parameter is 0, set 1 to reset the timings.
MAIN ZONE ACTUATION TYPE
This parameter allows you to configure the system to manage a mixing valve and an additional
pump on the main heating system (the use of the BE16 accessory board is required, not supplied
as standard).
The factory setting for this parameter is 0, set to 1 for the connection of a BE16 board.
Note: this parameter cannot be changed when an OT+ chronothermostat is connected.
MAIN ZONE ADDR
When MAIN ZONE ACTUATION TYPE = 1, this parameter allows you to set the address of the
BE16 board.
The factory setting for this parameter is 3 and can be set within the 1 - 6 range.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
this parameter.
MAIN ZONE HYDRAULIC CONF
When MAIN ZONE ACTUATION TYPE = 1, this parameter allows you to set the hydraulic
configuration of the main heating zone.
The factory setting for this parameter is 0 and allows a direct zone to be managed, set the parameter
to 1 for the management of a mixed zone.
Note: see the instruction sheet of the BE16 accessory board for more information about the use of
Jumpered
this parameter.
MAIN ZONE TYPE
zone valve management
This parameter allows you to specify the type of zone to be heated, it is possible to choose from the
following options:
0 = HIGH TEMPERATURE (factory setting)
1 = LOW TEMPERATURE
MAX CH SET
This parameter allows you to specify the maximum heating setpoint that can be set:
- range 20°C - 80.5°C, default 80.5°C for high temperature systems
- range 20°C - 45°C, default 45°C for low temperature systems.
Note: the MAX CH SET value cannot be less than MIN CH SET
MIN CH SET
This parameter allows you to specify the minimum heating setpoint that can be set:
- range 20°C - 80.5°C, default 20°C for high temperature systems
- range 20°C - 45°C, default 20°C for low temperature systems.
Note: the MIN CH SET value cannot be greater than MAX CH SET.
OTR
This parameter allows you to activate the thermoregulation when the system has an outdoor
temperature probe connected.
The factory setting is 0, the boiler always operates at a fixed point. With the parameter on 1 and an
outdoor temperature probe connected, the boiler operates in thermoregulation.
With an outdoor temperature probe disconnected the boiler always operates at a fixed point.

timing that has been set.
MAN AUTO
This parameter allows you to set the way of mode for passing from manual heating to automatic
