6.1.2 Replacing operating module (OM) ST7000
Information:
 Bearing plate with operating module, complete item no.: 2119917 (ST7000)
 The operating module, the high voltage inverter module and the touch screen
are located on the bearing plate.
 The ST7000 is the same for P3 appliances and the Mini range, because the
controls use the data in the IDM (identity module) to recognise whether the
screen needs to be aligned for vertical (P3) or horizontal (Mini range)
installation.
Check:
 If the easy touch welcome screen appears after switching on the appliance with
the main switch, the operating module and the display are working correctly.
Safety instructions:
 When working on the operating module switch off current to the appliance
(disconnect appliance with building's all pole separator with a min. 3 mm
contact gap) and secure against being switched on again.
 Caution: After switching off current to the appliance do not touch the high
voltage inverter module for at least 1 min. until the voltage has completely
dropped away.
 This work must only be undertaken by CONVOTHERM trained electricians.
Instructions - disassembling operating module:
 Disassemble the upper cover (see
service instructions “6.4
Disassembling and assembling
housing parts”).
 Lay the upper cover turned on its
head on something soft (to prevent
scratches).
