RHA - Ferroli

ACCESSORIES AND OPTIONAL EQUIPMENT
Electrical accessories
TP - Low and High pressure transducers (M). Allow the display of the suction and discharge pressures of compressors. Their presence
activates an advanced defrost and condensation control logic and the ATC (Advanced Temperature Control) to prevent high pressure alarm
due to high external air temperature.
RAG- Storage tank electrical heater (F). Keeps water in storage tank above freezing point to avoid risk of icing during winter stops it is
activated together with plate heat exchanger electrical heater.
TAT- High Temperature Thermostat (M). Two thermostats in series on compressors outlet pipes preserve operation not allowing temperature
to rise up than a specified non adjustable value.
CR- Remote control panel (F). Replies every control and visualization of the onboard control panel.
INT- Serial interface (M). Allows serial communication on RS485 by MODBUS protocol.
MTC - Magnetothermic switch (M). Magnetothermic switch on all loads place of fuses.
SS - Soft Starter (M). Soft starter on compressors allow to reduce to about a 60% nominal inrush current.
FLS - Flow switch (F). Paddle flow switch on the water circuit to avoid the risk of freezing if the water flow is shut off for some reason.
RIF - Capacitors for power factor corrections (M). Capacitors for power factor corrections increase power factor cos φ (> 0.91) and reduce
power input.
CSF - Voltage monitor and sequence meter (M). The device enables control of the correct sequence of power phases and the lack of any
phases.
KOP - Programmer clock (M). Allows the unit to be turned on and off depending on the programmed time setting (up to 14 switching actions
can be programmed as required throughout the 7 days of the week).
DCC - Head pressure control (M). (as standard for Low Noise unit AS and for eXtra Low Noise unit AX).
The device is made by 2 electrical drivers that, by means of phase cutting, control the fans speed rotation, with the scope of mantaining the
condensation pressure inside the correct operating limits.
