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 HUB SIReA1X is 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. 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.
Connect the system
In control board base SIReB1(X) the unit is
connected further with RJ12 (6p/6c) modular
cable if several units are to be connected in
parallell.
If an external room temperature sensor
SIReRTX (option) is used it is connected
using modular cable RJ11 (4p/4c) on HUB
SIReA1X.
The actuator for water control and outdoor
sensor SIReOTX is connected on PC Board
HUB SIReA1X.
Transformer for voltage supply of the valve
actuator is connected with quick terminal
block on PC Board Base SIReB1(X) (230V)
and 24V and onward to the actuator.
If return water temp. sensor SIReWTA is
used, it is connected with modular cable RJ11
(4p/4c) on PC Board Base SIReB1(X).
Control board Base SIReB1(X) 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
powered up.
For fixed installation requirements, remove
the supplied cable and plug. Perform the
installation in accordance with applicable
regulations.
Wiring diagrams
The wiring diagrams are in a separate section
at the end of this manual.
When external PC board Base SIReB1X is
used, wiring between the PC board base and
the unit must be done. Please see separate
manual for SIReB1X.
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 heating is on.
When the ID number must be changed the
unit must be disconnected from power.

Start up
System supplied with power. At the first start
up, the start-up wizard is run and the basic
settings are made. Fan and heating steps
are tested through the test program. Then a
status window is displayed.
At the first start up alarm and error codes
can occur, these will usually be reset without
actions.
Unit with mixing cabinet
When a mixing cabinet is used the supplied
Return temp. sensor SIReWTA must be
installed. SIReWTA is a clamp-on sensor
which is installed on the return water pipe as
close to the coil as possible. The sensor must
be insulated so it is not influenced by the
ambient temperature.
In order for the Return temp. Sensor to
detect the correct temperature in the return
circuit when the valve actuator is closed, a
circulation pump must be installed in the
secondary circuit.
Damper motor PSM01 must be installed on
the throttle spindle to the mixing cabinet.
Electrical connection between the damper
motor and PC board HUB SIReA1X and
transformer ST23024 (see the wiring diagram
at the end of the manual).
Start up
Select mixing cabinet On in the start-up
wizard.
Jumper settings
Actuator SDM24 (included in the valve kit) is
adjustable, this is done with jumpers. These
are located under the hatch of the actuator.
To SDM24 to work with SIRe the setting
should be as follows:
1

•Thermostat/Automaticfan
•Manual
Auto
When the set point value is undercut by 0.5 K
the fan starts at speed 1 and the valve motor
starts to open stepless. If a fully open valve is
not sufficient to maintain the temperature,
the fan control increases to a max of step 4.
The difference between the setpoint value and
the room temperature for the fan to increase
one step is set under Heating step diff., see
Installer menu > Settings heating > Heating
step diff.

Factory setting
Heating step diff.: 1.0 K (-10 K – 10 K)
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).
Return water temp.
If there is a demand for the temperature
of the return water not to exceed a certain
value, this function is activated under Return
water temp. A return water temperature
sensor (proximity sensor SIReWTA, option)
must then be installed on the return water
pipe.
Install Return temp. Sensor to Connected
and select max return temperature (15-90 °C)
using the turn wheel. During operation, this
function limits the valve’s degree of opening,
which reduces the flow and the return
temperature.

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
selecting 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.
Overheat protection
The overheat protection is designed to limit
the temperature of the heater to a maximum
of +90° C. If the temperature should exceed
95°C e.g. in the event of a faulty valve or
actuator, the fan starts to speed up to keep
the temperature down.
At the same time there is an overheating
alarm A2. At internal temperatures of +100°C
the fan runs at maximum speed.
If the unit cools, heating is automatically
reengaged. The alarm remains in the control
unit’s display. If the unit overheats twice
within an hour, the fan operates until the
alarm is reset.
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.
Frost protection function
The frost protection function is intended to
prevent the water coil from freezing.
When the fan is in operation the valve
actuator opens the valve at an internal
temperature below +15°C regardless of
whether there is a heating requirement. If the
internal unit temperature continues to drop,
e.g. at low ambient temperatures, insufficient
flow line temperatures, low flow or fault valve
function, the frost protection alarm A3 will be
triggered when the internal unit temperature
drops +5°C. The fan then also stops and when
the mixing cabinet is used the dampers is also
closed.
With return temp. sensor SIReWTA
connected an advanced alarm function
occurs. At return temperatures less than
+15°C the actuator will open regardless of
the heat demand. Alarm is triggered at return
temperature +7°C and the fan also stops.
When the fan is not running there is a heat
retention function that opens the valve when
the water’s return temperature falls below
+25°C regardless of heat demand.
Note! In event of repeated alarms,
overheating alarms and frost protection
alarms, carry out a thorough check and if
the fault cause cannot be found contact
authorised installer or Frico.

Table - Alarm
Alarm Cause Action
A1 Motor
alarm
Thermal switch has deployed.
One or several motors have
overheated. (Only units with
withdrawn thermal switches.)
Check that nothing is obstructing the
unit’s air intake and exhaust. When the
overheated motor has cooled the thermal
switch shuts again and the alarm can
be reset. At repeated alarms, check the
motors, replace damaged motors.
A2 Over heating
alarm
The temperature in the unit
has exceeded the alarm limit
for overheating.
Check that nothing is obstructing the unit’s
air intake and exhaust, the function of the
actuator and valve, flow temperature and
internal temperature sensor.
A3 Frost protection
alarm
The temperature in the unit has
fallen below the alarm limit for frost
protection. (Only applies to units with
internal unit temperature.)
Make sure that the ambient temperature
where the unit is installed exceeds +5°C.
Check the flow temperature, the flow of
hot water and the function of the actuator
and valve. In event of an alarm there a
risk that the battery is damaged, check
carefully for leakage and replace the
battery if damaged.
A4 Filter alarm Fixed run time before the filter alarm
has been reached.
or the external filter alarm has been
activated.
Replace or clean the filter, adjust any
alarm time based on how dirty the filter
was and reset the alarm.
A5 Ext. alarm External alarm input on SIReA1X has
been activated.
Check the external alarm.
