Utility release relay

The Utility release relay on the distributor panel may
be omitted if this does not violate the local Utility regu-
lations. The thermal relay (K1) installed in each Su-
perflat heater may be used as an Utility release relay.
For this, lead the release signal LF (230V 50Hz) from
the ripple control receiver, utility clock relay or other
clock meter into the connection chamber of each Su-
perflat heater and connect it to terminal „SH". Further
on, detach the power supply (L) of the electronic
charge control from terminal „L1" and connect it to
terminal „SH".
