SIRe Competent
Cause
SIReB1/B2/B1EC (internal pc-
board) do not communicate.
ID is set to 0 (Unit is running
continously).
Cables are not original.
The unit won't start.
Visual damage to SIReB1/B2/
B1EC.
Two or more SIReB1/B2/B1EC
have the same ID.
One or more SIReB1/B2/B1EC do
not have program.
Fault on or missing external
room sensor SIReRTX
connected to SIReB1/B2/
B1EC.
Wrong temperature is displayed
in SIReUA1.
Fault on or missing Return
water sensor SIReWTA
connected to SIReB1/B2/B1EC.
Wrong temperature is
displayed in SIReUA1.
Action
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.
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.
Perform a factory reset and reboot the system
(disconnect/ reconnect power).
Hardware failure - replace the SIReB1/B2/B1EC
pc-board. Contact Frico technical support.
Try to reset the alarm. Make sure all units have
different ID-settings and perform a Manual system
check.
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.
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.
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.
Return water temperature sensor is activated with
a SIReRTX-sensor connected - In the menu, disable
return water temperature sensor.
