7.2 Error message list
A warning or fault is always displayed in plain text as soon as it occurs.
The red signal light will also flash.
Warning (W): Boiler remains operational.
Fault (F): Boiler switches off immediately, heating circuit control and pumps remain on.

Type
Cause of error Elimination of error
Ex. temp. error W Sensor signal faulty Check sensor and sensor cable
DHW temp. error W Sensor signal faulty Check sensor and sensor cable
DHW temp2. error W Sensor signal faulty Check sensor and sensor cable
Remote control 1 error W Sensor signal faulty Check sensor and sensor cable
Remote control 2 faulty W Sensor signal faulty Check sensor and sensor cable
Remote control 3 error W Sensor signal faulty Check sensor and sensor cable
Remote control 4 error W Sensor signal faulty Check sensor and sensor cable
Boiler return temp. error W Sensor signal faulty Check sensor and sensor cable
Boiler temp. error W Sensor signal faulty Check sensor and sensor cable
Solar return temp. error W Sensor signal faulty Check sensor and sensor cable
Oil boiler temp. error W Sensor signal faulty Check sensor and sensor cable
Check primary air damper W Feedback signal varies from control
signal by more than 5% for 5 minutes
Actuator not turning.
Actuator incorrectly fitted
Incorrect direction of rotation
Damper movement impeded
Connection line damaged
Check actuator and cable
Correct fitting:
0% = damper closed
On actuator: swap connection for left
with right
Check dampers can turn
Check cable and connection
Storage temp low RELOAD W “Top storage tank” temperature
insufficient for heat supply
Info only – no error
Æautomatic acknowledgment
Store temp. mid error W Sensor signal faulty Check sensor and sensor cable
Store temp. up error W Sensor signal faulty Check sensor and sensor cable
Store temp. low error W Sensor signal faulty Check sensor and sensor cable
Return feed temp. too LOW
too long
W Return feed temperature too cold Check return feed lift, check sensor
Check sec. air damper W Feedback signal varies from control
signal by more than 5% for 5 minutes
Actuator not turning.
Actuator incorrectly fitted
Incorrect direction of rotation
Damper movement impeded
Connection line damaged
Check actuator and cable
Correct fitting:
0% = damper closed
On actuator: swap connection for left
with right
Check dampers can turn
Check cable and connection
Secondary flow temp. error W Sensor signal faulty Check sensor and sensor cable
Safety temp. limiter released F Boiler has overheated, substantial
reduction in heat consumption:
Heating and pump switches have
gone off.
Pump suddenly stops
Slide valves/cut-offs closed.
Release safety temperature limiter
(only possible once boiler has cooled
down)
Set switch back to “AUTO”
Check pump
Reopen slide valves/cut-offs
Flow temp.1 error W Sensor signal faulty Check sensor and sensor cable
Flow temp.2 error W Sensor signal faulty Check sensor and sensor cable
Flow temp.3 error W Sensor signal faulty Check sensor and sensor cable
Flow temp.4 error W Sensor signal faulty Check sensor and sensor cable
Safety time wrong air W Filling doors, soot doors or blanking
plate not tightly sealed
Check seal on doors. Readjust,
tighten screws if necessary
