Parameter
REGULATION
(0.1 to 25.5°C; 1 to 45°F) Intervention differential for setpoint.
Compressor Cut IN is Set Point + differential (HY). Compressor
Cut OUT is when the temperature reaches the setpoint.
(-50°C to SET; -58°F to SET) Sets the minimum value for the
setpoint.
(SET to 110°C; SET to 230°F) Sets the maximum value for
setpoint.
(-12.0 to 12.0°C; -21 to 21°F) Allows to adjust possible offset of
the thermostat probe.
(n; Y) n = not present, the defrost stops by time; Y = present, the
defrost stops by temperature.
(-12.0 to 12.0°C; -21 to 21°F) Allows to adjust possible offset of
the evaporator probe.
(n; Y) n = not present, the terminals 18-20 operate as digital
input; Y = present, the terminals 18-20 operate as third probe.
(-12.0 to 12.0°C; -21 to 21°F) Allows to adjust possible offset of
the third probe.
(n; Y) n = Not present; Y = present
(-12.0 to 12.0°C; -21 to 21°F) Allows to adjust possible offset of
the fourth probe.
(0 to 255min) This function is enabled at the initial start up of
the instrument and inhibits any output activation for the period
of time set in the parameter.
(0 to 50min) Minimum interval between the compressor stop
and the following restart.
(0 to 100; 100=P1, 0=P2) Allows to set the regulation according
to the percentage of the first and second probe, as for the
following formula (rtr(P1-P2)/100 + P2).
(0.0 to 24h00min, res. 10min) Allows to set the length of the
continuous cycle. Compressor stays ON without interruption
during CCt time. This is useful, for instance, when the room is
filled with new products.
(-50 to 110°C; (-58 to 230°F) Sets the setpoint used during the
continuous cycle.
(0 to 255min) Time during which the compressor is active in
case of faulty thermostat probe. With Con=0 compressor is
always OFF.
(0 to 255min) Time during which the compressor is OFF in case
of faulty thermostat probe. With CoF=0 compressor is always
active.
