When the internal thermostat triggers,
K11 must be opened and DIØØ "Controller
inhibit" must have a "0" signal. The
resistance circuit must not be interrupted!
When the external bimetallic relay (F16)
triggers, K11 must be opened and
DIØØ "controller inhibit" must have a
"0" signal. The resistance circuit must
not be interrupted!
