ACCESSORIES AND OPTIONAL EQUIPMENT
CR - Remote control (F). This can be used to select all the monitoring and display functions of the control unit on
the machine at a maximum distance of 100 meters away. It must be installed by using a cable with three strands
or three wires in PVC of the N07-VK type with a 1mm
2
section. The transmission line must be installed in a race-
way separate from any electric powering wires (230/400 V).
The control unit has the following buttons:
MODE key : used to select the operating mode
ON/OFF key : used to turn the unit ON/OFF and to reset the alarms
Mode + ON/OFF keys : used to access and quit the various menu levels
UP key: scrolls forwards through the menu items or increases the value of a parameter
Tasto DOWN:
scrolls backwards through the menu items or decreases the value of a para-
meter.
KOP - Programmer clock (F). 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).
RAG: Antifreeze heating element for the accumulation tank (M/F). Plug type. This activates in parallel with the evaporator’s
antifreeze heating element and keeps the water at a temperature able to prevent ice from forming when the unit remains idle
during the winter.
TAT- High Temperature Thermostat (M). Two thermostats in series on compressors outlet pipes preserve operation not allo-
wing temperature to rise up than a specified non adjustable value.
SND- External Air Probe (M). External air probe mounted near coil allows smart defrosting, climatic variation of setpoint and
enables heat pump stop reducing the external air temperature below a setpoint.
INT - Serial interface (F). Allows serial communication on RS485 by MODBUS protocol
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.
SS - Soft Starter (M). Soft starter for compressor, reduce the maximum starting current up to 60% of nominal starting current.
RIF - Capacitors for power factor corrections (M). Capacitors for power factor corrections increase power factor cos φ (>0.91)
and reduce power input.
MTC - Magnetothermic switch (M). Magnetothermic switch on all loads place of fuses.
CSF - Voltage monitor and sequence meter (M). The device enables control of the correct sequence of power phases and the
lack of any phases. It also ensures that the unit works within ± 10% the rated voltage (MIN=360 V - RATED=400V - MAX=440V).
It blocks the unit if the voltage is outside the limits provided for.
NOTE: (M): Installed (F): To be installed by customers
