Structural prerequisites

• The appliance must be installed via a permanent connection. Heater must be
earthed!
• The electric wiring should not be injured. After mounting, the wiring must not be
direct accessible.
• An all-pole disconnecting device (e.g. via fuses) with a contact opening width of at
least 3 mm per pole should be provided at the installation end.
• To protect the appliance, a fuse element must be fitted with a tripping current com-
mensurate with the nominal current of the appliance.

Load shedding relay

If further three-phase appliances are connected, a load shedding relay designed for
electronic instantaneous water heaters (CLAGE no. 82250) can be connected to phase
conductor L2.
To change the operating mode, after making the electrical connection and the initial
operation call up the settings menu. Then select the point "Load shedding".
Select "OK" to access the edit mode. To set a value of "0", "1" or "2" press and hold
or for two seconds. By plugging the jumper in accordance with the locking
function (see chapter »7. Initial operation« section »Locking function«) the load shed-
ding is activated.
Value Description
0 Operation without load shedding relay, factory setting
1 Operation with normal load shedding relay
2 Operation with sensitive load shedding relay
Operating mode 1 must be selected first, thus to check the correct operation of the
load shedding relay at low appliance output (35 degree celsius setpoint and low water
flow rate). Mode "2" must be selected if the load shedding relay flickers.
