2.The current time falls outside a set time period of the week program.

The figure shows the display with the following information:

-line one: the text PROG;

-line two: the time, the day and T1 and Tnet alternately (9.3 "The appliance's heating cycle");

-line three: the next scheduled switch-on time;

-line four: displays the text

PERIOD ACTIVATED.

These errors disappear automatically once the cause of the error has been removed, after which the appliance resumes operation by itself.

The display does not show what type of error has been detected. A comprehensive overview of the errors is provided elsewhere in the

manual (13 "Troubleshooting").

If, as end-user, you find the appliance in an error condition, you may attempt to restart the appliance by

pressing the button

However, if the error returns or occurs several times in a short time you must contact your service and maintenance engineer.

8.4Service condition

The figure shows the message

!!!WARNING !!!

MAX. BURNING HOURS:

SERVICE REQUIRED

In all modes, the temperature may at any moment drop below the desired temperature. The appliance then enters a heating cycle. This heating cycle is identical (9.3 "The appliance's heating cycle") for all basic operating modes.

Note

Setting and if necessary programming of the basic operating modes are described in the main

menu (11 "Main menu") chapter.

8.3Error conditions

The figure shows an example of an error condition. If the appliance enters this condition, the display will show the following information:

•line one: error code comprising a letter and two digits, followed by the error description;

•lines two to four: alternately, a brief explanation of the error, and a brief action to resolve the error.

S04: SENSOR ERROR

CHECK

SENSOR OR DUMMY

Caution

The displayed action to resolve the error may only be performed by a service and maintenance engineer.

There are various types of errors:

•LOCK OUT ERRORS

When the cause has been removed, these errors

require a reset with the button before the appliance can resume operation.

•BLOCKING ERRORS

SERVICE REQUIRED.Should this message appear, then the appliance is in need of a service and maintenance inspection. In that case, contact your service and maintenance engineer.

Note

The message SERVICE REQUIREDis based on the number of expired burning hours and the preset service interval. Should the service interval have been incorrectly selected, contact the service and maintenance engineer for instructions on how to adjust this. Information on the maintenance frequency is provided elsewhere in the

manual (14 "Maintenance frequency").

8.5Collector temperature warning

This message appears whenever the collector temperature is excessive. This message disappears automatically. If the message does not disappear, you must contact your service and maintenance engineer.
