Firmware 1.52 and 1.53 in WTM & RTC/WTC
Whole Modular Rack Type range (Electrolux WTM series) and Compact Rack
Type range (Zanussi RTC series and Electrolux WTC series)
New features and new procedures to avoid alarms 72, 73 and 78.
Since serial number 71300001 we have introduced the firmware release 1.52
in User Interface 0L1285 and MEC board 0L1284 for WTM and the firmware
release 1.53 in User Interface 0L1196 and MEC board 0L1291 for RTC/WTC
(spare part codes are not changed).
The new firmware has new features/procedures as listed here below.
Most of them can be implemented just replacing the Master board (either
User Interface in WTM or MEC board in RTC/WTC). Remaining ones can be
implemented only replacing both Master board and Slave boards.

Visible and modifiable tank levels and air-gap level (both maximum level
and working level)
Visible 2nd boiler temperature (US range), dryer temperature and feeding
motor current load
Boiler thermoregulation only during warm-up and wash/rinse (it avoids
boiler overheating during the stand-by
Parameters reset (the default is a WTM165 without dryer)
Pressure sensors calibration
Peak energy control (timeout alarms about all heaters are disabled)
Boiler temperature timeout alarm disablement
Dryer temperature cool-down procedure (to avoid alarms 72 and 73)
• the fan works even when machine switches from ready/wash to warm-
up;
• the fan works for 1 minute after switching-off (by control panel) if the
dryer temperature is over 60°C. Then it stops automatically;

• the alarm 72 appears only if the dryer temperature is over 80°C for 2
minutes while the fan is working
Alarm 72 and 73 may still appear if the machine is off/on by the main
switch instead of control panel because in that case the fan motor has to
stop working straight after switching-off if (for safety reasons).
See “Action in Field” below for more details about the “DT fan delay” /
“AFd” parameter and the cool-down procedure.
Reviewed air-gap draining procedure to avoid cavitation in case the air-
gap is already empty
Wash temperature and Prewash temperature timeout alarm (only during
warm-up and sanitization cycle for the Wash module, only the sanitization
cycle for the Prewash module)
