5.5 Electric connections
5.5.2 Connecting the multiple switch
The multiple switch (not supplied with the appliance) is connec
-
ted to the modular connector type RJ12 (connector X2) that is
placed at the rear of the appliance's display cover.
Dependent on the type of multiple switch that is used, a plug
RJ11 or RJ12 can be connected to it.
• Application of a 3-way switch with filter indication in all ca
-
ses requires an RJ12 plug in combination with a 6-core
modular cable.
• Application of a 3-way switch without filter indication in all
cases requires an RJ11 plug in combination with a 4-core
modular cable.
Refer to diagrams §11.2.1 to §11.2.4 for connection examples
multiple switch.
Other options include wireless remote control or a combina
-
tion of multiple switches.
he 4-way switch can also be used to activate a 30-minutes
boost mode by putting the switch to setting 3 for less than
2 seconds and directly turning it back to setting 1 or 2. The
boost mode can be reset by putting the switch to setting 3 for
longer than 2 seconds or by switching it to absence mode
(
).
5.5.1 Connecting the power plug
The appliance can be connected to an easily accessible,
earthed wall socket with the plug that is mounted to the ap
-
pliance. The electric installation must comply with the require
-
ments of your power company.
Make allowance for the 1000 W preheater.
Warning
The fans and control board carry a high volta-
ge. Always take the voltage from the appliance
by pulling the power plug when working on the
appliance.
5.5.3 Connecting eBus or OpenTherm connector
The Ubiflux can operate with Opentherm as well as with eBus
protocol. The setting of parameter 08 in the settings menu (see
chapter 13) lets you choose between eBus and OpenTherm.
An eBus or OpenTherm connection can be made with the
2-pole connector X1 at the rear of the display cover.
The
eBus protocol can for instance be used for coupling (cas
-
cade control) appliances (see §11.3). Because of polarity
sensitivity, always connect contacts X1-1 to X1-1 and contacts
X1-2 to X1-2 ; the appliance will not work when these contacts
are interchanged!
