SENSOR RESISTANCE
4.3 Control stop or lock-out
The code
8
,
5
or
9
can appear in the display.
•
Code
8
is a control stop and will appear if the measured
flow temperature ( t1 ) is higher than the flow temperature
set (T
set
flow). The boiler will start working again automati-
cally once the flow temperature falls below the flow tem-
perature set.
• Code 5 is a control stop from 3 till 10 minutes and
appears if the set flow temperature ( t1 ) has already been
reached and the heating demand still exists.
•
Code
9
is a lock-out and appears if the maximum tem-
perature rise is exceeded or if the
d
T between the sup-
ply and return temperature
≥
45°C or a rate of rise in the
flow temperature > 1°C/sec. And also at a boiler-start with
no through flow or insufficient water. The boiler will try to
restart after 10 minutes.
z
Every 10 minutes the boiler will try to restart until the cause
has been removed.
• Code 9 is a lock-out and can appear in the following
situation:
- the lock-out down input (between terminals 5 and 6 on X9)
has been activated (= opened).
z
The lock-out will disappear once the cause has been removed!

No through flow
during venting
cycle.
Insufficient water. Check the minimum water pressure, read off the gauge and check
for leaks.
No through flow. Check that the pump is working; turn the spindle with a screwdriver,
if that works but the pump still does not respond, check the wiring;
that is in order the pump is faulty.
Too much air in the system. Vent the system.
Wrong pump wiring.
Check wiring from and to control unit.

has responded;
replace the heat
exchanger after
finding and solv-
ing the cause. Heat exchanger faulty. Check wiring between heat exchanger fuse.
Insufficient water. Check the minimum water pressure, read off the gauge and check
for leaks.
No through flow. Check that the pump is working; turn the spindle with a screwdriver,
if that works but the pump still does not respond, check the wiring;
that is in order the pump is faulty.
