5. PROTECTIVE SYSTEMS
SysAqua has several alarms to protect its components and users.
5.1. CONDENSATION PRESSURE
Three alarm levels can protect the pressure circuits from condensation that is too high:
1. If the condensation pressure approaches the limit (function of the operating mode), a compressor is
stopped to reduce the capacity of the SysAqua. If the pressure drops below a preset threshold, the
initial calculation of the capacity is again used to manage compressors.
2. If the rst protective system is not enough, the shutdown sequence of the circuit is activated if the
pressure limit is reached. The circuit has an automatic reset if the pressure drops below the dened
threshold.
3. If the high pressure pressure switch is activated, the circuit is immediately stopped and requires
manual resetting.
5.2. EVAPORATION PRESSURE
Three alarm levels can protect the pressure circuits from evaporation that is too low:
1. If the evaporation pressure approaches the limit (function of the operating mode), a compressor is
stopped to reduce the capacity of the SysAqua. If the pressure rises above a preset threshold, the
initial calculation of the capacity is again used to manage compressors.
2. If the rst protective system is not enough, the shutdown sequence of the circuit is activated. If the
pressure drops, the circuit is restarted. If the threshold of three alarms per hour is reached, the reset
becomes manual.
3. If the low pressure pressure switch is activated, the circuit is immediately stopped and requires
manual resetting.
5.3. BACKFLOW TEMPERATURE
Excluding deicing, the second compressor stage is stopped if the backow temperature reaches 125°C.
The rst stage stops at a temperature of 130°C. If the rst stage stops, an alarm is activated. The reset is
automatic. A manual reset is required if the alarm is triggered a second time within one sliding hour.
In deicing mode and the next 5 minutes; both compressors of the circuit are stopped if the backow
temperature reaches 130°C and restarts after at least 3 minutes if the temperature is below 100°C.
5.4. ANTI-FREEZE PROTECTION
The anti-freeze protective system is used to prevent damage to the water circuit. This protection depends
on the glycol concentration congured.
The alarm is activated if the water inlet or outlet temperature falls below the SpFrPrt value (automatically
modied according to the glycol level).
This alarm is automatically acknowledged
if the temperature rises above 2 K at
SpFrPrt in less than 5 minutes.
If a water temperature is less than
SpFrPrt for more than 5 consecutive
minutes, the FrPrt alarm is triggered;
likewise if a water temperature drops
below the LoLm value (depends on the glycol level). An acknowledgement is required to remove the alarm.

5.4.1. WATER FLOW/RETURN TEMPERATURE DIFFERENCE PROTECTION
The temperature difference protective system safeguards against a sensor fault other than a disconnection
or short circuit. The protective system is activated if the
temperature difference between the water inlet or water
outlet temperature is too high.
SysAqua is shut down if the temperature difference
between the water inlet and outlet becomes too great. The
acknowledgement is automatic with a hysteresis of 2k.
The blocking alarm is activated if the alarm occurs 3 times in 15 minutes.
