Connecting the supply
Incoming electricity supply is connected to terminal block
(X1) in HBS 16 via cable gland (UB1). The cable must be
dimensioned according to the applicable norms.
HBS 16 can be connected with either 400 V 3NAC or 230
V 1AC.
400 V 3NAC : Connect incoming supply according to the
markings on terminal (X1).
NOTE
Depending on the house main fuse and to avoid the
load monitor slowing down the compressor, other
loads in the house should be moved from L3 to L1
and L2.
230 V 1AC : Install the supplied straps between terminals
L1 and L2 as well as between L2 and L3 on incoming ter-
minal block (X1). Connect incoming supply according to
the terminal markings.

Miniature circuit-breaker
The automatic heating control system, circulation pumps
and their wiring in HBS 16, are internally fuse protected
with a miniature circuit breaker (FA1).

fuse protected in HBS 16, with a miniature circuit breaker
(FA2).
Temperature limiter
The temperature limiter (FD1) cuts the current supply to
the electrical addition if the temperature rises between
90 and 100°C and can be manually reset.
Resetting
The temperature limiter/emergency mode thermostat
(FD1-BT30) is located in the tanks' electrical connections.
The temperature limiter is reset by firmly pressing in its
button.

during transport.
