Quick guide/start up
Check that all constituent parts are present
(see section Constituent parts).
Advice about location
Control unit SIReUB1 has an integrated room
temperature sensor and is installed so that it
is easily accessible to the user.
PC Board base SIReB1X is installed close to
the unit. Wiring between the PC Board Base
SIReB1X and heating fan must be laid for
230V.
RJ12 (6p/6c) modular cables, which are
available in different lengths, are used to
connect the PC board and the control unit.
Longer cables are available as options.
Maximum cable lengths see section Options.
To prevent unauthorised people from
accessing the Control unit it can instead
be placed in another area and an external
room sensor, SIReRTX (option), can be
installed in the premises to sense the correct
temperature.
Note! Internal sensor SIReIT02 shall be
mounted in the fan exhaust in the fan heater
unit in intended holder.
Connect the system
In PC board Base SIReB1X the unit is
connected further with RJ12 (6p/6c) modular
cable if several units are to be connected in
parallel.
If an external room temperature sensor
SIReRTX is used it is connected using
modular cable RJ11 (4p/4c) on SIReB1X.
PC board Base SIReB1X in/at the unit and
control unit SIReUB1 is connected with RJ12
(6p/6c)modular cable after the other units are
powered up.
Power supply for electric heat must be
connected separately (check manual for the
fan heater unit).
