Accessories
• AERSET: The AERSET accessory allows the
automatic compensation of the operating setpoint of the unit to which it is connected,
based on a 0-10V MODBUS input signal.
Mandatory accessory: AER485 or MODU485A
• AER485: RS-485 interface for supervision systems with MODBUS protocol.
• VT: set of four anti-vibration mounts, to be fitted below the unit base.
• DCPX: Low ambient device for cooling operation below 10 °C down to -10 °C. Pressure
transducers read the condensing pressure and
the electronic controller varies fan speed to
maintain adequate pressure for correct unit
operation. It also allows a correct operation
by heating with external temperatures above
30 ° C and up to 42 ° C.
• DRE: Soft starter (current reduction of about
30% for single circuit units, 26% for two circuit units, 22% for three circuit units). Only
available for 400V-3-phase power supply.
Factory fitted only.
• GP: Protection grille protects the external coil
from accidental damage.
• PGS: Daily/Weekly Programmer. Allows two
daily time-clock programmes (two switch on/
off cycles) and different programmes for each
day of the week.
• RIF: Power factor correction. Connected in parallel
to the motor allowing about 10% reduction of
input current. Must be requested at time of order
and is available factory fitted only.
• AERWEB300: Accessory AERWEB allows remote
control of a chiller through a common PC and an
ethernet connection over a common browser; 4
versions available:
AERWEB300-6: Web server to monitor and remote
control max. 6 units in RS485 network;
AERWEB300-18: Web server to monitor and remote
control max. 18 units in RS485 network;
AERWEB300-6G: Web server to monitor and remote control max. 6 units in RS485 network with
integrated GPRS modem;
AERWEB300-18G: Web server to monitor and
remote control max. 18 units in RS485 network
with integrated GPRS modem;
• DUALCHILLER: Simplified control system to
switch on/off and control two chillers in a single system (using Aermec GR3 command), as
if they were a single unit.
• MULTICHILLER: Control system for multiple
parallel installed constant flow chillers providing individual chiller on/off and control
capability.
• TRX1: Metal cap that replaces the plastic cap,
mounted as shipping protection, for immersion heater holes in the buffer tank.
• PRM1: FACTORY FITTED ACCESSORY. A
manual reset pressure switch wired in series
with the existing high pressure switch
installed on the compressor discharge line.
• TP3: As standard
COMPATIBILITY with the VMF SYSTEM For
more information on the system refer to the
manual.
