1.7 Outdoor Unit
All outdoor units are pre-charged. For further information
please refer to the Product Data Sheet, Chapter 2.
It includes :
• Axial fan.
• Outdoor coil with hydrophilic louver fins for RC units.
• Outlet air fan grill.
• Service valves” flare” type connection.
• Interconnecting wiring terminal block.
• Fresh air motor for FLO N 7-14 (optional).
1.8 Tubing Connections
Flare type interconnecting tubing to be produced on site.
For further details please refer to the Installation Manual.
1.9 Accessories
ASK (All Season Kit):
For low ambient working conditions in cooling, an ASK can be installed inside the
outdoor unit. This kit allows cooling operation down to outdoor temp of -10 ºC by
gradually controlling the outdoor fan speed motor.
RCW Wall Mounted Remote Control
The RCW remote control is mounted on the wall, and controls the unit either as an
infrared remote control or as a wired controller. The wired controller can control up to
10 Indoor units with the same program settings and adjustments.
For further details please refer to Optional Accessories, Chapter 14.
1.10 Inbox Documentation

12Α.1.7. RV Fault (comp units only)
This test is performed every time the unit is switched from OFF/STBY to OPER
in Heat mode or changes operation mode from COOL/DRY to HEAT (this
applies also in AUTO COOL/HEAT mode).
If ICT is lower than 35
0
C at the time of mode change, then at the first
occurrence of 15 min continuous COMP operation, ICT is compared with ICT
reading when the COMP was switched from OFF to ON 15 min before. RV fault
is defined when ICT decreases in more than 5
0
C.
In this case, the COMP will stop and the SB led will blink. This fault is reset after
going to SB or mode change.

112Α.6.1. Heating Mode - General
• Compensation Procedure:
The compensation procedure comes to solve the problem of the temperature
distribution by height during heat mode according to this procedure.
• When I feel is OFF during heat mode: RT= RAT – CTV.
When I feel is ON during heat mode: RT= RCT.
• CTV is a compensation temperature value to be used from the following table (CTV
table).
• RCV is a reference compensation value (relation between cells).
• IOC is a compensation value when IFAN is OFF.
• The values of RCV and IOC to be set in the following table are taken from the RCV
and IOC table below depending on the model.
CTV table:

. IFAN operation rules for RC and SH.
• As a general rule for RC and SH groups,
IFAN will be switched ON according to the following graph:
Note 1:
When ICT is faulty:
When the compressor switches from off to on (excluding deicing), IFAN will be on in
ANY speed.
When the compressor switches from on to off, the IFAN will change to low speed for 30
seconds and then it will be off.
Note 2:
Once the compressor is ON, 6 min later, excluding protection modes, IFAN will be
forced to Low until it reaches the ANY speed, and then IFAN will operate according
to items and above. This rule can be re-performed only on the next compressor
restart.
• In SH or RC group, IFAN will operate for min 30 sec , after HE’s turned
off, where in a case it has to be OFF, it will be forced to low speed.
