OPERATING MODE

12.1 Operating mode (x [[)

During normal operation the code-display shows the
status (position in cycle) of the boiler, with the t -dis-
play indicating the actual flow temperature.
The digits or letters in the code-display have the follow-
ing meaning:
Code Description
0
Standby; there is no heat demand from control system
1
Pre-ventilation (pre-ventilation time 30 seconds, post ventilation time 3 seconds)
2
Ignition
3
The burner is firing (flame detection)
4
n/a
5
Waiting mode; check for sufficient air flow using fan and air pressure differential sensor (LDS)
Control stop (burner off + post ventilation) :
- flow temperature T1 > setpoint + 5°
6
- flow temperature T1 > desired setpoint modulating control + 5°
- flow temperature T1 > parameter 1
- difference flow T1 and return T2 > 10° (factory setting); Starting condition is [ 10 °.
End of heating demand, pump run on time. During cycling prevention delay-time the boiler will remain in
7
state 7 and will not react to heat demand.
8
n/a
b
Shut-off mode (see section 12.4)
h
Forced full load (HIGH)
l
Forced part load (LOW)
t
Gas leakage control
c[l Burner cooling

12.2 Read-out mode (X [[)

Read-out mode is used to display various values. Press
the m key until ! appears in the code window (dot
flashes). Select the required code using the s key.
