Dx-coil unit
Dx-coil (Direct Expansion Coil) unit is a kind of temperature control equipment working with Lossnay unit and Mr.Slim outdoor
unit to control Return Air temperature or Supply Air temperature.
2.2 SA (Supply Air) temperature control
1. Basic function
2.Two temperature control method
2.1 RA (Return Air) temperature control
As same as air-conditioner, users set the target return air temperature on the remote controller and then Dx-coil unit will operate
to heat up or cool down the room temperature.
This picture shows the system of LGH-100RVX-E and GUG-02SL-E as example.
Users set the target supply air temperature on the remote controller and then Dx-coil unit will maintain the supply air
temperature close to the setting temperature.

• System pattern X: One remote controller
• System pattern Y: Two remote controllers
• System pattern Z: M-NET connection
Depending on the pattern, the way to operate system, available functions, information can be monitored etc. are different. See

CHAPTER2System configurations/ 2.Technical notes
1.5 External fan speed control without Lossnay remote controller
When Lossnay remote controller (PZ-61DR-E) is not used in the system pattern X or Z, Lossnay fan speed can be controlled by
external input like 0-10VDC (CN26) or volt-free contact (CN17).
Refer to the installation manual and the technical manual of Lossnay unit for more detailed information such as how to set, how
to select.
The selection of Temp. priority mode or Fan speed priority mode can be set. Please refer to No.10 on page 25 and 26.

1Fan speed 1 and 2 When Lossnay supply fan is the fan speed 1 or 2, Dx-coil unit always switches thermo-OFF.
2Night purge When Lossnay is in Night purge mode, Dx-coil unit always switches thermo-OFF and PZ-01RC is
the same as the normal operation screen.
PZ-61DR-E or AE-200E is required for the Night-purge function.
3Heating stops when the OA temp. is
19 ˚C or higher
[GUG-03SL-E, SA temperature control and heating mode only]
When the OA temperature is 19 ˚C or higher, Dx-coil unit switches thermo-OFF to protect the
compressor of the outdoor unit.(This “OA temperature” is the detected temperature by outdoor
unit. It is not the detected temperature by Lossnay unit.)
4Intermittent operation - When the OA temperature is between -10 ˚C and -15 ˚C, Lossnay oparates 60 minutes ON and
10 minutes OFF. During the ‘10 minutes OFF’, Dx-coil unit switches thermo-OFF.
- When the OA temperature is lower than -15 ˚C, Lossnay operates 5 minutes ON and 55 minutes
OFF. During the ‘5 minutes ON’, Dx-coil unit switches thermo-OFF.
5Defrost and heating standby mode During defrost and heating standby mode, Lossnay supply fan stops but exhaust fan continues to
run as factory setting.
6Error indication During heating or cooling modes, PZ-01RC displays an error code on its screen.
During fan mode, PZ-01RC changes to heating mode and displays an error code. If automatic
change to heating mode is not required, please set the function No.7 to pattern B. Refer to page
24 for details.
7Drain pump The drain pump operates during cooling mode and operates for 6 minutes after Dx-coil unit stops.
The drain pump will make a noise while operating.

3. The conditions when Dx-coil unit is forcibly thermo-OFF
4. Water level sensor
5. Drain pump operation
Under the conditions listed below, Dx-coil unit is always and forcibly thermo-OFF. Dx-coil unit cannot be thermo-ON for about 10
minutes after the condition is canceled.
• When the supply fan of Lossnay unit is stopping, fan speed 1 or fan speed 2.
• When the Lossnay unit is operating at Night-purge mode.
• When outdoor air temperature detected by a thermistor in Lossnay unit is less than -15˚C.
• When outdoor air temperature detected by a thermistor in Outdoor unit is more than 19˚C, if GUG-03SL-E is used at SA
temperature control and heating mode.
• When the system (Lossnay unit, Dx-coil unit, Outdoor unit) has an error.
The Dx-coil unit has a water sensor to detect the water level in the drain pan and has a drain pump to drain the condensation
water during cooling mode.
If the drain pump cannot drain the water properly, the water level in the drain pan increases and the water sensor detects the
water, and then nally an error occurs to avoid the water overow.
During the error is occurring, the supply fan of Lossnay unit will continue to run at fan speed 2 or 1 to avoid that the water y
out from the product.
The drain pump becomes ON at the conditions listed below.
• When Dx-coil unit is cooling mode.
• When the water sensor is detecting the water.
• When the lead wire connector that should be connected CN10 of PCB B is disconnected.
• When the drain pump test run switch is ON.
The drain pump continues to run for six minutes after the condition is canceled except for the test run.

CHAPTER3Specifications / 5. Characteristic curve
Attention
1. The running current and input power are based on 230V/50Hz.
2. The cooling and heating capacities are based on the air conditions listed below and the rated airow of fan speed 4.
Cooling Indoor: 27°CDB/19°CWB Outdoor: 35°CDB/24°CWB
Heating Indoor: 20°CDB/15°CWB Outdoor: 7°CDB/6°CWB
3. The rst gure in ( ) of the capacity specication is the heat recovery energy of the Lossnay unit. The second gure is the
capacity specication for the Dx-coil connected to the outdoor unit.
4. ”Performance index” is the calculated value at the temperature conditions above and is reference purpose only.
Performance index = Total capacity ÷ total power consumption of outdoor unit and Lossnay unit
5. The external static pressure listed above includes the static pressure loss of the Dx-coil unit when using a 50cm straight duct
between the Lossnay and Dx-coil units. When the duct work between the Lossnay and Dx-coil units is longer and/or bent,
the pressure loss of the duct work should be included in the pressure loss calculation.
6. The designed airow of the system (Lossnay, Dx-coil and duct work) at fan speed 3 and 4 should be kept within “Airow range
at SP3 and SP4” listed above. This range is shown as the solid line in graphs of the characteristics curve.
If the Lossnay airow is out of this range, the compressor of the outdoor unit may stop for self-protection purposes.
7. By installing the Dx-coil unit with a Lossnay unit, the air blow noise level is quieter at fan speed 4 as shown below.
LGH-50RVX-E: about 4dB quieter, LGH-65RVX-E: about 7dB quieter
LGH-80RVX-E: about 6dB quieter, LGH-100RVX-E: about 7dB quieter
LGH-150,200RVX-E: about 3dB quieter
LGH-150,200RVXT-E: about 3dB quieter, LGH-250RVXT-E: about 4dB quieter
8 .Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute
less to global warming than a refrigerant with higher GWP, if leaked to the atmosphere.
This appliance contains a refrigerant uid with a GWP equal to 1975. This means that if 1kg of this refrigerant uid would be
leaked to the atmosphere, the impact on global warming would be 1975 times higher than 1kg of CO2, over a period of 100
years. Never try to interfere with the refrigerant circuit yourself or disassemble the product yourself and always ask a professional.
9. On-site measurements by pitot tube method could be as much 20% difference from JIS test room conditions. If the measuring
point is close to sources of turbulence like bends, contractions and dampers etc., it is difficult to measure air volume correctly.
A straight duct length more than 10D (D=duct diameter or equivalent) from the source of turbulence is recommended for
correct measurement.
On-site measurement should therefore be measured in accordance with BSRIA guideline
(Commissioning Air Systems. Application procedures for buildings AG3/89.3(2001)).

Recovery of static pressure losing by Dx-coil unit.
*This graph is just for illustrative purposes.
When connecting Dx-coil unit to Lossnay unit, the original Lossnay P-Q curve (Curve.1) will decrease because of adding
pressure loss by Dx-coil unit (Curve.2).
One solution to recover this static pressure decrease is setting fan power up function of Lossnay unit (Curve.3).
This fan power up function is only available when Lossnay remote controller PZ-61DR-E is used.
Select adequate setting data number which is associated with fan power up level shown in below table at the function setting
page of PZ-61DR-E.
Refer to Lossnay and PZ-61DR-E installation manual for more detailed information.
