START DEFROST (i1F = dFr)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will
restart only if the digital input is disabled otherwise the instrument will wait until the “MdF” safety time is
expired.
INVERSION OF THE KIND OF ACTION: HEATINGCOOLING (i1F = Htr)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
ENERGY SAVING (i1F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+ HES
(parameter) sum. This function is enabled until the digital input is activated.
DIGITAL INPUTS POLARITY
The digital input polarity depends on the
“i1P”
parameter.
i1P=CL:
the input is activated by closing the contact.
i1P=OP:
the input is activated by opening the contact

ALARM RECOVERY
Probe alarm
“P1”
starts some seconds after the fault in the related probe; it automatically stops some

Temperature alarms
“HA”
and
“LA”

normal values.
Alarms
“EA
” and
“CA”
(with i1F=bAL) recover as soon as the digital input is disabled.
Alarm
“CA”
(with i1F=PAL) recovers only by
