High superheating set point
The alarm situation is notified after the high superheating alarm activation
delay (Et29)
Low superheating set point
In this situation an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Additional integral time in low superheating condition
MOP activation set point.
Above this value an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Pressure set-point during PI regulation in MOP condition
Proportional part of the PI regulation during MOP condition
Additional integral time in MOP condition
LOP activation set point.
Below this value an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Pressure set-point during PI regulation in LOP condition
Proportional part of the PI regulation during LOP condition
Additional integral time in LOP condition
Delay on activation of the MOP alarm from condition occurrence in cooling
mode.
If the MOP condition is not solved within the Et47 time an alarm is notified and
the relevant circuit is switched OFF.
PID regulation in heating mode
PID proportional band in heating mode
PID integral time in heating mode
PID derivative time in heating mode
Superheating set-point in heating mode
Superheating dead band in heating mode
High superheating set point
The alarm situation is notified after the high superheating alarm activation

Low superheating set point
In this situation an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Additional integral time in low superheating condition
MOP activation set point.
Above this value an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Pressure set-point during PI regulation in MOP condition
Proportional part of the PI regulation during MOP condition
Additional integral time in MOP condition
LOP activation set point.
Below this value an additional integral time is added to normal regulation in
order to speed up recover the normal working condition.
Pressure set-point during PI regulation in LOP condition
Proportional part of the PI regulation during LOP condition
Additional integral time in LOP condition
Delay on activation of the MOP alarm from condition occurrence in heating
mode.
If the MOP condition is not solved within the Et65 time an alarm is notified and
the relevant circuit is switched OFF.
