Figure 9.3 shows an example of ‘Blocking errors’. In this case, the text HISTORIE OF ERRORS is followed by (B).

Figure 9.4 shows an example of the ‘Lock out errors’. In this case, the text HISTORIE OF ERRORS is followed by (L).

nRemark

For an overview of all errors and the possible causes, please refer to chapter ’10 Troubleshooting’.

The appliance history sub-menu is used to display the burning hours, the number of ignitions, the number of flame errors, and the number of ignition errors.

Bring up the menu for displaying the appliance history via:

•S: APPLIANCE HISTORY

Figure 9.5 shows an example.

Bring up the menu for displaying the appliance selection via:

•S: SELECT APPLIANCE

The appliance selection has been correctly preset in the factory. Figure 9.6 shows the relevant display.

If a program-controlled pump is installed (Installation, see paragraph 3.10.6) then this can be turned ON or OFF via:

•S: PUMP RELAY

The standard setting for the pump relay is OFF.

Figure 9.7 shows the related display.

If the mode WEEK PROGRAM or EXTRA PERIOD is active, then the setting for mode WEEK PROGRAM or EXTRA PERIOD has priority over the ON/OFF selection for the pump relay in the service menu.

Example

One of the week program periods is currently active. The pump relay setting is OFF within this period. If the pump relay is set ON in the service menu, the pump will nonetheless remain OFF. The pump will only switch ON once the week program period has ended.

To aid servicing, the ThermoControl has a service interval which defines the frequency of maintenance by the service and maintenance engineer based on the number of burning hours. Refer also to paragraph 11.2.
