OPTIONAL ACCESSORIES
The descriptions of these additional components can be found in Chapter OPTIONAL ACCESSORIES.
P121 .................................... Front air bottom panel . Unit base noise insulation with special
bottom panel for OVER version. Restriction: Non- compatible with “P122
Bottom air blind panels” for OVER version.
P122 .................................... Bottom air 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 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 w 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 de 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.
