2.3 DESCRIPTION OF ACCESSORIES
2.3.1 Factory-fitted standard components
Electronic expansion valve
expansion valve, designed for the control and continuous regulation of the amount of refrigerant fed into the evaporator. Changes in thermal
load may be followed quickly, so as to achieve optimised consumption.
Electronic circulator
standard on the unit, electronically controlled and high efficiency.
Water-side safety valve
Valve installed on the hydraulic circuit to control overpressure - setting 6 bar
Flow switch (flow presence signalling)
Device whose task is to control and signal the circulation of water in the plate heat exchanger. This component is of fundamental importance
because it shuts down the unit and makes it safe by preventing the formation of ice.
Dry contact on/off remote
contact on the terminal board that allows the unit to be switched on and off.
Dynamic set-point
the regulator allows the set-point to be modified by adding a value according to the temperature of the external air probe.
Three-phase relay for sequence/absence monitoring
signals the presence of all three phases in the correct sequence.
