-

-

-

P121 .................................... Front air intake + bottom panel. Unit base noise insulation with special

bottom panel for OVER version. Restriction: Non-compatible with "P122

Bottom air intake + blind panels" for OVER version.

P122 .................................... Bottom air intake+blind panels. Blind frontal panel for OVER version. The

accessory allows the intake air from the bottom of the machine. Restriction:

Not compatible with "P121 Front air intake + bottom panel" for OVER

version.

601 ...................................... Solenoid valve on liquid line.

A548 .................................... Constant prevalence. Automatic system for the air pressure control in the

aisle. The system controls the supply fans rotation speed to keep constant

the air pressure via a differential pressure transmitter connected to the

microprocessor control.

P091 .................................... Back-up module controller. The system guarantees the microprocessor

power supply for a few minutes, in case of supply voltage failure. (size E1

excluded).

P171 .................................... Kit for air -45°C MCH axial AC (condenser series GR). Kit for operations

with low ambient air temperature down to -45°C. For machine start up and

operation with very low ambient air temperatures (between -20°C and -

45°C).

P172 (1) .............................. Kit for air -45°C axial AC (condenser series T-MATE). Kit for operations

with low ambient air temperature down to -45°C. For machine start up and

operation with very low ambient air temperatures (between -20°C and -

45°C).

P191 .................................... Power supply for condenser. Electrical power supply for remote

condenser from the indoor machine electrical board. The optional includes

magneto-thermic switches for condenser fans and the control/alarm signals.

383 ...................................... Numbered wirings + UK requests;

4181 / 4182 / 4184 / 4185 ... Serial cards:

4181 – Serial card MODBUS;

4182 – Serial card LON;

4184 – Serial card BACNET MS/TP RS485;

4185 – Serial card BACNET OVER IP.

A492 .................................... Water leakage detector + additional sensor. Supplied in mounting kit.

A511 .................................... Smoke detector. Supplied in mounting kit.

A521 .................................... Fire detector. Supplied in mounting kit.

P141 .................................... Analogue set-point compensation. - Analogue set point compensation

according to an external analogue signal at Customer care.

The microprocessor control, through the additional module "expansion

card", can manage a compensation signal of the return air setpoint by

analogue input (0...1V; 0...5V; 0,5...4,5V; 4...20mA; 0...20mA). The

compensation curve allows to assign a temperature setpoint offset

respectively to the minimum and maximum signal managed by the input.
