Display faults on the thermostat’s screen
The thermostat can also relay boiler faults. Therefore, first
check whether the fault is not caused by the connected boiler.
Refer to the boiler’s manual for additional explanation regar-
ding the boiler fault.
If it reads “Err” instead of the
temperature then there is so-
mething wrong with the boiler’s
thermostat. Check whether the
wiring has been properly connec-
ted to the boiler (to the Z-ready/
bus-thermostat connection) and
inside the thermostat itself (refer to chapter 2.1). Consult your
installer if the complaint persists.
• Is the boiler plugged into
the socket?.
• Check whether the wiring to
the boiler is correct.
• Maybe the thermostat is
faulty. Consult your installer.
A connected boiler displays a fault. There are minor faults
which sort themselves out
and also disappear automa-
tically. To be sure still check
out the boiler.
