To run the unit
temporarily
without external
control select
mode 0.
Each unit should
have a unique ID on
its SIReB1X card.
Quick guide/start up
Check that all constituent parts are present
(see section Constituent parts).
Advice about location
PC board Base SIReB1X and PC board HUB
SIReA1X are installed close to the unit.
Control unit SIReUA1 has an integrated room
temperature sensor and is installed so that
it is easily accessible to the user. 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 con-
nect the PC board and the control unit. Long-
er cables are available as options. Maximum
cable lengths see section Options.
To prevent unauthorised people from acces-
sing 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 control 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 SI-
ReRTX (option) is used it is connected using
modular cable RJ11 (4p/4c) on HUB SIReA1X.
Outdoor sensor SIReOTX is connected to
the terminal block on PC board Hub SIReA1X
Control board Base SIReB1X in/at the unit
and control unit SIReUA1 are connected by
PC board HUB SIReA1X with RJ12 (6p/6c)
modular cables, after the other units are po-
wered up.
Power supply for electric heat must be con-
nected separately (check manual for the fan
heater unit).
Wiring diagrams
The wiring diagrams are in a separate section
at the end of this manual.
Enter ID/Operation without control unit
The control system can control one or more
units in parallel (max 9). Each unit must get
a unique ID number (1-9) which is set in the
ID selector of the PC board. E.g. Unit 1: ID=1,
unit 2: ID=3
If the external control for some reason has
not been installed the unit can still be run
temporarily. The ID selector is then set to
mode 0 see the image below.
The function is half speed and half heating
output
When the ID number must be changed the
unit must be disconnected from power.

Operating modes
Operating modes (without mixing cabinet)
Control is based on the three operating
modes:
•Thermostat/Manualfan
•Thermostat/Automaticfan
•Manual
Thermostat / Manual fan
The thermostat just controls the heating and
the fan runs continually. The fan speed is set
manually. The fan symbol is marked in the
status window, select desired speed with the
rotary dial and confirm. (High speed limit is
step 4 for SE06-15 and step 2 for SE20/30).
When the setpoint value is fallen below by
0.5 K the first heating step is engaged , if the
temperature falls further the next heating step
is engaged, etc. (SE06-15, 20 has 2 heating
steps, SE30 has 3 heating steps).
The difference between the set point value
and the room temperature that controls the
engagement of the Heating step is set under
Heating step diff., see Installer menu > Set-
tings heating > Heating step diff.
Thermostat / Automatic fan
The thermostat controls both the heating and
the fan. The fan speed is set manually in the
status window.
Manual
The fan speed and heating is set manually in
the status window. The heating can be set to 2
or 3 steps. Heating is blocked by the outdoor
temperature, see: [Installer menu > Settings

If the temperature continues to fall below
+18.5°C another output step cuts in (cuts
out at +19.0°C). For 3 output steps the last
step is engaged at +17.5°C and switches off at
+19.0°C.
Factory setting
Heating step limit: 2 (SE06-15, 20) 3 (SE30)
Sensor calibration
If the sensor displays the wrong values these
can be calibrated. Some display errors may
occur, but this is primarily due to the location
(cold/hot surfaces etc). The value + or – adds
to or subtracts from the measured value
(for example +2K gives an increase of the
displayed value of 2 degrees).

Alarm and error codes
SIRe has different alarms and error codes for
safe and problem free operation.
If alarms or error codes have been indicated
these must be reset in order to return to
normal operation, for example activating the
heating again. Fan mode is active even when,
for example, the over heating alarm has been
indicated.
Displaying alarm and error codes
In event of alarm or error the alarm/error
code is shown in the status window. In event
of alarm/error code the unit it applies to is
displayed.
See Table - Alarms and Table – Error codes.
Reset alarm
Note! Before resetting, check that the fault is
rectified and there is nothing to prevent the
unit from being recommissioned!
When the fault is rectified, the alarm is
reset by pressing the forward arrow and selec-
ting Reset alarm and then confirm. If several
units give an alarm at the same time, the fact
that there are several alarms is indicated, but
only one is shown in the display. By resetting
that alarm the next alarm can be read.
At the first start up alarm and error codes
can occur, these can usually be reset without
action.
Power failure
Note that in case of power failure the time
settings need to be checked, if the time is not
set correctly week program will be affected.
Overheat protection
SE06-15:
The over heating protection is intended to
restrict the exhaust temperature to 70 °C.
At 70 °C an output step is tripped off. If the
temperature continues to rise all output
is interrupted at 75 °C. If the temperature
continues to rise despite this, for example
because of a faulty contactor, the fan will
start to spin at 70 °C to keep the temperature
down. At the same time there is an over
heating alarm, see Table - Alarm. At internal
temperatures of +80 °C the fan runs at
maximum speed.
If the unit cools the output is engaged again.
The alarm remains in the control unit’s dis-
play. If the unit overheats twice within an
hour, the alarm must be reset before the hea-
ting can be engaged again, the fan operates
until the alarm is reset.
SE20-30:
The over heating protection is intended to
restrict the exhaust temperature to 85 °C.
At 85 °C an output step is tripped off. If the
temperature continues to rise all output
is interrupted at 90 °C. If the temperature
continues to rise despite this, for example
because of a faulty contactor, the fan will
start to spin at 85 °C to keep the temperature
down. At the same time there is an over
heating alarm, see Table - Alarm. At internal
temperatures of 95 °C the fan runs at
maximum speed.
If the unit cools the output is engaged again.
The alarm remains in the control unit’s dis-
play. If the unit overheats twice within an
hour, the alarm must be reset before the hea-
ting can be engaged again, the fan operates
until the alarm is reset.
Note! In event of repeated alarms and over
heating alarms, carry out a thorough check
and if the fault cause cannot be found contact
authorised service personnel or Frico.
