compressor operation or eventually switch off the circuit in alarm. A manual action on the controller will be needed in order
to clear the alarm.
1.4 Available sensors
1.4.1 Pressure transducers
Two types of electronic sensors are used to measure suction, discharge and oil pressure on each circuit. The range of
each sensor is clearly indicated on the sensor casing. Discharge and oil pressures are monitored using a sensor of the
same range.
1.4.2 Temperature sensors
The evaporator water sensors are installed in the entering and leaving side. An outdoor temperature sensor is mounted
inside the chiller. Additionally each circuit installs a suction and discharge temperature sensors to monitor and control the
superheated refrigerant temperatures.
On refrigerant-cooled inverters additional sensors immersed into the cooling plate measure the temperature of the drives.
1.4.3 Thermistors
Each compressor is equipped with PTC thermistors which are immersed into motor windings for motor protection.
Thermistors trip to a high value in case the motor temperature reaches a hazardous temperature.
1.4.4 Leak detectors
As an option the unit can be equipped with leak detectors to sense the air in the compressor cabin and being able to
identify a refrigerant leakage in that volume.
1.5 Available Controls
1.5.1 Evaporator pumps
The controller can regulate one or two evaporator pumps and takes care of automatic change-over between pumps. It’s
also possible to prioritize the pumps and temporarily disable one of the two. The controller is also able to control the pump
speeds if the pumps are equipped with inverters.
1.5.2 Condenser pumps (W/C units only)
The controller can regulate one or two condenser pumps and takes care of automatic change-over between pumps. It’s
also possible to prioritize the pumps and temporarily disable one of the two.
1.5.3 Compressors
The controller can regulate one or two compressors installed on one or two independent refrigerant circuit (one compressor
per circuit). All the safeties of each compressor will be managed by the controller. Embedded inverter safeties are handled
by the inverter onboard electronic and only notified to the UC.
1.5.4 Expansion Valve
The controller can regulate an electronic expansion valve per each refrigerant circuit. MicroTech™ embedded logic will
always guarantee the best operation for the refrigerant circuit.
1.5.5 Evaporator Flow Switch
Although the flow switch is offered as an optional, it is mandatory to install one and connect it to the digital input terminals
in order to enable chiller operation only when a minimum flow is sensed.
Operating the unit by-passing the flow switch input or without an appropriate flow switch may damage the
evaporator due to freezing. Operation of the flow switch must be checked prior to start up the unit.
1.5.6 Condenser Flow Switch
Condenser flow switch is offered as an option but it’s not mandatory to connect it to the digital input terminals. This input
can be eventually closed by a jumper even if for a more reliable use it’s suggested to mount it. If not installed, other
protection will activate in order to protect the unit.
