Note
■ The control circuit must be supplied
with power without blocking by the
power supply utility. This means a sep-
arate power supply is required for the
control circuit.
■ A separate connection for the control
circuit calls for the internal wiring to be
changed. This may only be carried out
by a heating contractor according to
the electrical wiring diagram.
■ The control circuit power supply and
the cable for the power-OFF signal can
be combined in a 5-core cable.
