EXCLUSIVE
- PREHEATING
Setting PREHEATING = 1 the boiler's domestic hot water function
activates. This function keeps the water in the domestic hot water
exchanger hot, to reduce standby times when a request is made. When
the preheating function is enabled the symbol P comes on with a steady
light at the top with respect to the hot water icon. During burner ignition
following a preheating request, the symbol P starts flashing.
To deactivate the preheating function, set the parameter to PREHEATING
= 0, the symbol P switches off.
The function is not active when the boiler is OFF.

- TYPE OF ACTUATION
Set the parameter in question to ITRF05/AKM (default value)
- TYPE OF HEAT REQUEST
This parameter allows you to specify the type of heat request, it is
possible to choose from among the following options:
THERMOSTAT (factory setting): the heat request is generated with an
ON/OFF thermostat
REC10 MASTER: the heat request is generated by the REC10
MASTER; in this case the REC10 assumes the function of MACHINE
INTERFACE
- TYPE OF ZONE
This parameter allows you to specify the type of zone to be heated, it
is possible to choose from among the following options:
HIGH TEMPERATURE (factory setting):
LOW TEMPERATURE
- MIN SET HEAT
This parameter allows you to specify the minimum heating setpoint that
is possible (range 20°C - 80.5°C, default 40°C for high temperature
systems - range 20°C - 45°C, default 20°C for low temperature
systems)
- MAX SET HEAT
This parameter allows you to specify the maximum heating setpoint that
is possible (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)
- CHANGING NAME
This parameter allows you to attribute a specific name to the heating
zone
- POR
This parameter allows you to enable the central heating programming
timing for the zone concerned if the heat request is carried out using a
room thermostat
Time schedule not enabled = 0
When the room thermostat contact closes the heat request is always
met without any time band limitation
Time schedule enabled = 1
When the room thermostat contact closes the heat request is enabled
according to the programming timing.
Note: in this case make sure that the operating mode of the zone is set
to AUTO in the STATE menu.
5.2.3 Time band schedule function (room thermostat)
Whenever the heating system is managed by a room thermostat, and
therefore without any time schedule, it is possible to tie the heat requests
coming from the device to programmable time bands by setting the
parameter POR = 1 (see section "5.2.2 Configuration of the zone" ), in other
cases it is always enabled.
To access this function:
