STANDARD PROGRAM
Options: ON, OFF
Default: ON
The settings can be reverted to default values in this menu. However this does not apply to the following
menus: APPLICATION, LANGUAGE, TEMP. UNIT and COUNTER. Desired changes must be done in the
menus in question. It is possible to choose only the alternative ON in this menu because when the default
settings have been changed the menu will automatically change into OFF mode.
LANGUAGE
Options: GERMAN, ENGLISH, FRENCH, FINNISH, SWEDISH, CZECH
Default: GERMAN
Various languages can be selected in this menu. The selected language will retain even if the standard
program is reverted.
TEMP. UNIT °C/°F
Options: °C, °F
Default: °C
The temperature scale can be either Celsius (°C) or Fahrenheit (°F). The selected temperature unit will retain
even if the standard program is reverted.
COUNTER
Range: 00000H00M...65535H59M
The counter calculates the time, in minutes and hours, during which the heating has been on. The counter
reading will retain even if the standard program is reverted. To reset the counter, select RESET with the
VALUE button and then press ENTER to reset.
ALARM MESSAGES
In the event of an alarm, the display starts flashing in one second intervals and the alarm relay closes (con-
nectors 5 and 6). The word ALARM appears on the top line and the reason of the alarm on the bottom line.
This alarm display alternates with the measured values so that each option is displayed 3 seconds at each
time. The heating relay opens (connectors 8 and 9) turning off the heater, unless the continuous heating
has been selected. The alarm message appears on the display still for 5 seconds after fault clearance. It is
possible to change menu options during the alarm.
