When the outdoor unit is installed above the indoor unit an oil trap is required every 5m along the suction
line at the lowest point of the riser. Incase the indoor unit is installed above the outdoor, no trap is

CONTROL SYSTEM
12.
CONTROL SYSTEM
12.1
General
The control and logic system is managed by the indoor PCB controller with regards to all functions
and protections excluding Deicing. The DUO OU7 R410A is equipped with stand -alone internal
deicer integrated on the outdoor PCB (TYPHOON - 4A 6.3).
12.1.1
Deicing operation:
The outdoor coil temp ‘ is detected by 2 OCT sensors (outdoor coil temp’) the deicing procedure
will be activated if one of the sensors is sensing a temp’ ≤ -6ºC, and will stop when the outdoor coil
will reach to12ºC or max 10 Min. once the deicing protection is activated it will include both units at
the same time. Method of defrosting is by reversing the heat pump cycle to cooling mode, stopping
the outdoor fan and keeping the comp’ running, the unit will resume to its normal operation after
the deicing procedure will be deactivated. Min. deicing time is 2.5 Min.
12.1.2
Deicing interval:
At first start up deicing will not be activated for the first 45 Min., and will go to STBY mode after
every defrosting this timer will start a new cycle.
12.1.3
Discharge Pressure Protection – (Heating Mode)
The PCB is equipped with two additional sensors for each refrigerant circuit, measuring the
refrigerant hot gas Temp’ in heating mode.
In case of a high discharge Temp’ in one of the sensors will be detected. The PCB will set the
outdoor fan to ON and OFF intervals, in order to reduce the suction pressure
And as a result, the hot gas temp’ as well.
OFAN ON - 70 ºC
OFAN OFF - 75 ºC
