Communication
error
ID is set to 0 (Unit is running
continously).
Cables are not original.
Set an ID, run a Manual system check.
Make sure communication cables are correct (Frico
original cables has a circuit diagram indicating how
the contacts shall be crimped on to the cable.)
In multiple unit system, check that you have
230VAC to all units.
In Installer menu - Installer status screen, check that
all units ID are listed and that no extra units are listed.
When all units are powered up run a Manual system
check.
Disconnect power, set ID=0 and reconnect
power to test the B1/B2/B1EC pc-board.
Hardware failure - replace the SIReB1/B2/B1EC
pc-board. Contact Frico technical support.
Visual damage to SIReB1/B2/
B1EC.
Two or more SIReB1/B2/B1EC
have the same ID.
Try to reset the alarm. Make sure all units have
different ID-settings and perform a Manual system
check.
Program
error (No
program)
Try to reset the alarm. Disconnect power, set ID=0
and reconnect power to test the B1/B2/B1EC pc-
board - result? If the unit is running act as if it was an
E1 Communication error. If it is not running, contact
Frico technical support.
Room
sensor error
Wrong temperature is displayed
in SIReUA1.
Try to reset the alarm. Check connections and
cable. False errors can occur in conjunction with
communication error, check that all other alarms
have been reset. Measure resistance, 47kOhm at
25°C.
If the sensor intentionally has been removed, run a
Manual system check to exclude it from the system.
If a return water sensor (SIReWTA) is connected
but not activated, the system will interpret that
value as a room temperature value, activate return
water sensor. When SIReWTA is used, SIReRTX
shall be connected to the SIReA1X.
Fault on or missing Return
water sensor SIReWTA
connected to SIReB1/B2/B1EC.
Return water temperature sensor is activated with
a SIReRTX-sensor connected - In the menu, disable
return water temperature sensor.
SIReB1/B2/B1EC (internal pc-
board) do not communicate.
Try to reset the alarm. Check connections and
cable. False errors can occur in conjunction with
communication error, check that all other alarms
have been reset. Measure resistance, 47kOhm at
25°C.
If the sensor intentionally has been removed, run a
Manual system check to exclude it from the system.
Wrong temperature is
displayed in SIReUA1.
Return water
temp. sensor
error.
The unit won't start.
Perform a factory reset and reboot the system
(disconnect/ reconnect power).
One or more SIReB1/B2/B1EC do
not have program.
ID Error
Fault on or missing external
room sensor SIReRTX
connected to SIReB1/B2/
B1EC.

Try to reset the alarm. Check connections,
modular cables and terminals, between all units
and components. Systematically shift position of
communication cables to identify a broken terminal
or cables.
