Waiting position

The LED of the on/off button and if necessary one of the LED’s of the

domestic hot water Keep hot function are on. The appliance is ready for

responding to the demand for CH or domestic hot water.

0 Pump overrun

After the operation of the CH, the pump has an overrun. This overrun time

is set to the value according to parameter 8 (see § 7.3; factory setting is 1

min). This setting can be changed. Note: If there is a hot water demand

during this period, the overrun time is cancelled. The controller will

automatically run the pump for 10 seconds, once every 24 hours, to

prevent it from getting stuck. This activation of the pump takes place at the

time of the last heat demand 24hrs later. In order to change this time, set

the room thermostat higher for a while at the desired time.

1 Required temperature reached

The controller can temporarily block the heat demand and stop the burner.

This blocking takes place because the required temperature has been

reached. When the temperature has dropped sufficiently, the blocking is

cancelled.

2 Self-test

The controller regularly checks the connected sensors. During the check,

the controller does not carry out any other tasks.

3 Ventilate (Fan)

On starting, the fan is first brought to the starting speed. When the starting

speed has been reached, the burner is ignited. Code

3 is also visible

after stopping the burner, when post-purge takes place.

4 Ignite

When the fan has reached the ignition speed, the burner is ignited by

means of electric spark ignition. During ignition the code

4 appears. If

the burner is not ignited, another ignition attempt is made after about

5 seconds. If the burner has still not fired after the fourth ignition attempt,

the controller indicates a fault. See § 8.1.

5 CH operation

An on/off thermostat can be connected to the controller, if necessary in

combination with an outside sensor. See the Electrical diagram § 10.1.

When heat is demanded by a thermostat signal, the fan runs (code

3 )

and the burner is ignited (code 4 ), followed by the CH operating

condition (code 5 ).

During CH operation, the fan speed and hence the power of the appliance

is adjusted. This is done in such a way, that the temperature of the CH

water is controlled towards the set CH supply temperature. In the case of

an on/off thermostat, the CH supply temperature is set at the operating

panel. In the case of an outside sensor, the CH supply temperature is
