The water heater’s temperature must be limited to 55 °C, if
it is connected to a shower. The service menu parameter
“Temperature Limit“ (“tL”) must be set to a value less or equal
55 °C (in consultation with the customer) and the lock level must
be activated.
When the device is operated with preheated water, it must be
ensured that this temperature is limited to 55 °C as well.
• If the appliance is to be recommissioned under different
installation conditions it may be necessary to alter the
maximum power rating.
• This should only be done by a competent installer.
• To re-set the maximum power rating use a screwdriver
(compliant to EN 60900, current issue) to short circuit the two
pins as shown in Fig. 13.
• This will reset all heater parameters to factory settings.
• Value “21” (“12” for DEX12) will flash in the display panel until
the maximum power rating has been selected.
