Load shedding relay
If further three-phase appliances are connected, a load shedding relay designed for
electronic instantaneous water heaters (IN . 82250) can be connected to phase con-
ductor L2 .
To avoid possible jitter of the load shedding relay caused by low power consumption
(low temperature set point and low water flow rate) the “Load-shedding-mode” can be
activated as followed:
• Disconnect the appliance from the power supply (e .g . by switching of the fuses)
• Take the jumper off the power electronics and change to position “
