1.5 Control
The microprocessor indoor controller, and an infrared remote control, supplied as standard, provide complete operating function and programming. The unit is designed with an on unit control board as well. For further details please refer to the Operation Manual, Appendix A.
1.6 Outdoor Unit
The PXD outdoor units can be installed as floor or wall mounted by using a wall supporting bracket. The metal sheets are protected by anti- corrosion paint work allowing long life resistance. All outdoor units are pre-charged. For further information please refer to the Product Data Sheet, Chapter 2.
It includes :
A Rotary Compressor mounted in a soundproofed compartment.
Axial fan.
Outdoor coil with hydrophilic louver fins for RC units.
Outlet air fan grill.
Service valves” flare” type connection.
Interconnecting wiring terminal block.
1.7 Tubing Connections
Flare type interconnecting tubing to be produced on site. For further details please refer to the Installation Manual, Appendix A
1.8 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 on this manual.

3) Thermistor Temp reading doesn’t change ­a) This test is performed only once after a unit is switched from OFF/STBY
to operation. At the first occurrence of 10 min continuous COMP operation, the current ICT are compared with those when the COMP was switched from OFF to ON 10 min before. If the T is less than 3 thermistor is regarded as defective.
b) The ICT no-change error can be disabled together by connecting a 4.7k

This test is applied only in compressor units where 4.7k resistor is not connected to the OCT. The 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 or (this applies also in AUTO COOL/HEAT mode). If ICT is lower than 35 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 more than 5 In this case, the COMP will stop and the SB LED will blink. The fault is reset after switching to SB or after mode change.

preset temp. according to the following table:
Forced Operation Mode
Cooling 20 ºC 22 ºC Heating 25 ºC 28 ºC
Temp: Set – desired temperature selected Fan: Any Timer: Interact with Sleep Timer I-FEEL: ON or OFF
Pre-set Temp for : MBX, P2000, PX Models
1. While under the forced operation, the temperature compensation schedule is disabled.
2. The forced operation is activated when the mode button on the Display Board is used to switch the unit to COOL or HEAT mode.
3. The IFAN is always set to Autofan Speed in forced operation.
Pre-set Temp for : FCD, RWK ,ELD, ECC, WAX, WNX, WMN Models
NOTES
The Sleep mode is activated by using the SLEEP button on the R/C. In Sleep Mode, the unit will automatically adjust the SPT to turn up/down the room temperature (RT) gradually to provide maximum comfort for the sleeping user.
Sleep is treated as TIMER function. Therefore, the TIMER LED is activated similar to TIMER function.

11.14.1 Time Adjustment in SLEEP Mode
In 10V4, the user can make use of the Off-Timer to extend the Sleep Time from 7 hours to 12 hour (max). The operation of the new “Extended Sleep Mode” is illustrated by the graphs below.
Case 1 is the Standard Sleep Mode, which is the only sleep mode in the previous version of MCU. The A/C unit simply works for 7 hours, then goes to SB.
Case 2 is the new Extended Sleep Mode. If an active Off-Timer is set to turn off the A/C between 7-12 hour, relative to the starting of Sleep, the Sleep time is extended. And, instead of going to SB at the 7th hour, the A/C will work until reaching the Off­time.
Case 3 is an exception to case 2. The Sleep Mode will not be extended to the Off­Time when the Off-Timer is preceded by an On-Timer, which is also between 7-12 hour.
Case 1 : Standard Sleep Mode
Condition : Off-timer is not set or is beyond 12 hour.

11.15.2 By Remote Control Settings:
a. STEP 1: TURNING ON THE POWER.
Turn ON the power, make sure that the unit is in operation.
b. STEP 2 : ENABLE SELF-TEST MODE
1) Use the remote control to send the first settings to display / indoor unit HEAT mode, HIGH IFAN, set temperature to 16 ºC, no I-FEEL Sleep or any other timer settings are needed.
2) Cover the IR transmitter components in the remote control so that it will not transmit the signals to the indoor unit display.
3) Use the remote control to send the second settings to display / indoor unit COOL mode, LOW IFAN, no I-FEEL Sleep or any other timer settings.
4) Uncover the remote control IR transmitter and change the temperature settings. If the display/indoor unit receive the settings properly the following steps will start:
c. STEP 3: MODEL SETTING CONFIRMATION
1) The STAND-BY and COOL LEDS will indicate the operation mode as follows:
