, this parameter allows you to the setpoint value of heating zone 1. The factory
setting for this parameter is
P4.28
and can be programmed within the
P4.29
and
P4.28
range.

P5 (DHW menu)
P5.10
This parameter allows you to set the delayed starting of the boiler in domestic hot water mode.
The factory setting for this parameter is 0 and can be programmed within the range 0 - 60sec.
P5.11
This parameter allows you to activate the following functions related to the operation of the boiler in
domestic hot water mode:
0 = no function; the boiler in domestic hot water mode starts immediately and uses the related
domestic hot water thermostats, i.e. it switches off at se5°C and switches back on at
se4°C (factory setting)
1 = domestic hot water delay function, so the boiler in domestic hot water mode starts with a delay
equal to the value of the parameter
P5.10
2 = FUNCTION NOT AVAILABLE ON THIS MODEL
3 = the boiler uses absolute domestic hot water thermostats, i.e. in domestic hot water mode it
always switches off at 65°C and switches back on at 63°C, independently of the domestic hot
water setpoint that has been set
4 = functions 1 and 3 are active
P8 (CONNECTIVITY menu)
P8.01
This parameter is used to manage the boiler remotely. Three values are available for this pa-
rameter:
0 = FACTORY-SET VALUE. The interface on the machine is operational but the boiler can
also be controlled remotely if the Modbus device for WiFi/Bluetooth connection is attached
to the connector under the shelf (optional accessory, not supplied as standard)
1 = remote boiler control is disabled, only the interface on the machine is operative. If con
-
nected, the Modbus device for WiFi/Bluetooth connection is ignored, while a connection
error is generated when connecting a Modbus remote control (REC10) and the error
<<COM>> is shown
2 = you can connect a Modbus remote control (REC10) to control the boiler; the interface on
the machine is disabled and <<RCTR>> is shown on the display. Only the MENU button
for changing parameter P8.01 remains active.
P8.03
This parameter is used to enable remote boiler management using an OpenTerm device:
0 = With the OT+ function disabled, you cannot control the boiler remotely using an OT+
device. If this parameter is set to 0, any OT+ connection is instantly interrupted, and the
“xx” icon and “OTB” message on the display are switched off
1 = FACTORY-SET VALUE. With the OT+ function enabled, you can connect an OT+ device
to control the boiler remotely. When you connect an OT+ device to the boiler, the “xx” icon
lights up on the display and “OTB” appears.
