9.18.3 Anti ‐ freezing
The alarm will be activated when the outlet water temperature sensor is less than 4°C. It turns off when the temperature becomes
higher than +6°C.
9.18.4 Sensors alarm
The alarm will be activated in the case of a short or open circuit of any connected and enabled sensor.
The alarm will be activated also when the temperature becomes higher than the sensors’ upper limit of 100°C or less than the
lower limit of ‐ 50°C.
9.18.5 Timeout inverter
Supposing the controller does not communicate with the driver board of the compressor, the time out alarm will be activated in
order to prevent a system’s control loss.
9.18.6 ON/OFF remote
In case the unit is remote controlled by a remote digital input.
9.18.7 High pressure
If the on board pressure transductor detects a pressure higher than 41 bar, the alarm will be activated.
In this case the compressor will stop immediately. The alarm will reset when the pressure decreases under 36 bar.
9.18.8 High pressure flow switch (in series with the compressor outlet probe)
If the pressure switch on the machine detects a pressure higher than 42 bar the alarm will be active.
In this case, the compressor will be immediately stopped. The alarm resets when the pressure drops below 32 bar.
9.18.9 Low pressure
If the on board pressure transductor detects a pressure lower than value set from the controller (as a function of operating mode
and/or of the model) the alarm will be activated. In this case the compressor will stop immediately. The alarm will reset when the
pressure goes over the set hysteresis.
