1 Control cable to the contactor of the 2nd appliance (e.g. elec-
tric storage heater).
2 Control contact opens when switching the instantaneous
water heater on.
15.3 DHW output
The DHW output is subject to the mains voltage, the appliance's
connected load and the cold water inlet temperature. The rated
voltage and rated output can be found on the type plate (see chap-
ter "Troubleshooting").
