local regulations in force.
- The appliance is fitted with the standard network power supply
cable with a lateral earth and a prong earth. Plug the cable into a
wall socket connected to the earth.
- The appliance is designed to be used at 230V 50Hz.
- Use of the appliance can be adapted to climate conditions using
the outdoor temperature sensor, available as an option. (art. No.
10510100). The sensor should be placed on the north wall of the
house, at a height of approximately two metres. In addition, the
sensor should be connected to socket X3, connection 3-4
(see

-You can connect a standard enabled/disabled room thermostat
with a contact without potential. We offer a room thermostat as
part of option art. No. 10800018. Connect this to socket X3,
connection 1-2
(see page 19).
-The AM 3-11 unit, available as an option, allows you to connect a
second circuit. This unit is connected to socket X8 on the MCBA
using the connection cable supplied. This unit has a relay to sup-
ply the pump for the second central heating circuit, a relay to open
the external three-way valve, and a relay to close this valve. The
MCBA is set in the standard manner for the three-way valves, with
a 150-second time delay for the control. Please see the connec-
tion diagram below.
-You can also connect the AM3-2 alarm unit to the MCBA as an
option. This unit emits a signal through a relay when the burner is
operating and the boiler breaks down.
Please see the connection diagram below.
