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.
Confirm that WTA is connected to the SIReB1/
B2/B1EC and securely fastened to the return
water pipe and compare with what the actual
temperature is.
SIReRTX-sensor must not be connected to SIReB1/B2/
B1EC when the intention is to use 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.
Try to reset the alarm. SIRe can control different types
of units, e.g. Fan heaters or air curtains, water or
electrical units, but they cannot be combined. The only
exception is ambient air curtains in combination with
either electrical or water heated units of the same model.
Check the datalabels of your units and 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.
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.
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.
Make sure communication cables are correct (Frico
original cables has a circuit diagram indicating how the
contacts shall be crimped on to the cable.)
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. If the error is not rectified SIReUA1 must be
replaced.
Try to reset the alarm. The system will only support
one control unit, disconnect and reset alarm.
Make sure all units are from the same release, contact
Frico technical support.
