Characteristics

Accessories• AERSET: The AERSET accessory allows the

automatic compensation of the operating set-point of the unit to which it is connected, based on a 0-10V MODBUSinput signal. Mandatory accessory: AER485 or MODU-485A

• AER485: RS-485 interface for supervision sys-tems with MODBUS protocol.

• AVX: spring anti-vibration mounts Select the AVX model from the compatibility table.

• DCPX: Low ambient device for cooling oper-ation 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. Also permits correct unit operation in heating mode with external air tempera-tures above 30 °C and up to 42 °C.

• DRE: Soft starter (about 26% with two com-pressors, 22% with three compressors). 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 com-mon 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 net-work;

AERWEB300-18: Web server to monitor and remote control max. 18 units in RS485 net-work;

AERWEB300-6G: Web server to monitor and remote control max. 6 units in RS485 net-work with integrated GPRS modem;

AERWEB300-18G: Web server to monitor and remote control max. 18 units in RS485 net-work with integrated GPRS modem;

• DUALCHILLER: Simplified control system to switch on/off and control two chillers in a sin-gle system (using Aermec GR3 command), as if they were a single unit.

• MULTICHILLER: Control system for multiple parallel installed constant flow chillers pro-viding individual chiller on/off and control capability.

• TRX1: Metal cap that replaces the plastic cap, mounted as shipping protection, for immer-sion heater holes in the buffer tank.

• VT: anti-vibration mounts, to be fitted below the unit base.

• PRM1 and PRM2 : FACTORY FITTED ACCESSORY. A manual reset pressure switch wired in series with the existing high pressure switch installed on the compressor discharge line.

• COMPATIBILITY with the VMF SYSTEM For more information on the system refer to the manual.
