Functions
CS-A120TE
Outdoor Unit
Hot-start Control (Heating)
● The indoor fan stops until the Evaporator
piping temperature will be reached.
Automatic Restarting Control
● 7 minutes automatic restarting at Cooling,
Soft Dry operation
Sleep Mode Auto Control
● The Fan is switched to Low fan speed and the
unit will be stopped after 5 hours
● The setting temperature will be raised by 1°C
at the starting and by 1°C one hour later (Soft
Dry of Cooling Operation)
● The setting temperature will be dropped by
2°C at the starting and by 3°C one hour later
(Heating operation).
Deice (defrost) Control
● Both the indoor and outdoor fan stops during
deicing
● Hot start after deice ends
● Starts operation when indoor piping
temperature drops below temperature setting
60 ± 10 minutes after heating start or deice
ends
● Operations LED flashes.
Overload Protection
● Thermostat OFF if the Piping temperature
exceeds 100°C
Automatic Operation Determination
● Selects cooling, dry or heating with the indoor
intake sensor
25°C or higher.....cooling
21 to 24°C ........... dry
20°C or lower ......heating
● 5-minutes automatic restarting is activated
instead of 7-minutes
Overload Protection
30sec. Forced Operation Control
● Once the compressor is activated it does not
stop for 30 secs
● Stops immediately with remote control stop
Anti-freezing Control For The
Evaporator
● Compressor will be stopped when the
Evaporator’s piping temperature is 0°C or
less for three minutes
● Restarting at 12°C or higher (Time Delay
Safety Control has a priority)
Airflow Direction Control
Automatic Airflow Direction Control
● The louver automatically swings up and down
(Cooling, Soft Dry)…horizontal and 30°
downward
● The louver is set at 60° downward during
Heating Operation
● The louver is set at horizontal when the fan is
stopped
Airflow Direction Manual Control
● Can be set within a range at horizontal to 60°
downward
