DEHUMIDIFICATION MODE
a) MTV2, AUX1 and heater are always off.
b) If Tr ≥ 25ºC, then MTV1 and AUX2 will be ON for 3 minutes, and then OFF for 4 minutes.
c) If 16ºC ≤ Tr < 25ºC, then MTV1 and AUX2 will be ON for 3 minutes, and then OFF for 6 minutes.
d) If Tr < 16ºC, then MTV1 and AUX2 will be turned off for 4 minutes.
e) At the end of the above dehumidification cycle, the system will decide the next dehumidification
control option. Indoor fan will run at low speed throughout the dehumidification process.
AUTOMODE
Without Electric heater and With Electric Heater as Booster
a) Every time the unit is turned on, MTV1 is on while AUX1, AUX2 and fan are off. MTV2
and the heater are always off. After 120 seconds, the subsequent operation mode is
decided according to the following:
1) If the coil temperature sensor (Ti1) ≥ 36°C, then MTV1, AUX1 and fan turn on or
off according to HEAT mode.
2) If Ti1 < 36°C, then MTV1, AUX2 and fan turn on or off according to COOL mode.
b) Unit remains in AUTO COOL or AUTO HEAT mode throughout the operating cycle until
the user changes the mode manually or restarts the unit.
c) Should the Ti1 sensor fail or be damaged, auto mode will not function.
With Electric Heater as Primary Heat Source
a) If the current running mode is AUTO COOL mode, it will change over to AUTO HEAT mode
upon satisfying all the conditions below:
1) Ts ‐ Tr ≥ 1°C (or – 4ºC if economy contact is activated).
2) MTV1 has stopped ≥ 10 minutes.
b) If the current running mode is AUTO HEAT mode, it will change over to AUTO COOL mode
upon satisfying all the conditions below:
1) Tr ‐ Ts ≥ 1°C (or + 4ºC if economy contact is activated).
2) MTV1 has stopped ≥ 10 minutes.
Note: AUTO COOL or AUTO HEAT operations are the same as COOL or HEAT mode
respectively.
C.1.5.2.
Without Thermoelectric Valve Configuration
COOL MODE
a) Heater, AUX1, MTV1 and MTV2 are always off.
b) If Tr ≥ Ts + 1ºC (or + 4ºC if economy contact is activated), then cool operation is activated and AUX2
is turned on. Indoor fan runs at set speed.
c) If Tr < Ts, then cool operation is terminated and AUX2 is off. Indoor fan is turned off.
d) The range of Ts is 16 ‐ 30ºC.
e) Indoor fan speed can be adjusted to low, medium, high and auto.
f) When the unit is turned off, indoor fan shut down after 5 seconds.
LOW TEMPERATURE PROTECTION OF INDOOR COIL
a) If Ti1 ≤ 2ºC for 2 minutes, then AUX2 is turned off. If low speed is selected via user interface, then indoor
fan runs at medium speed. If medium or high speed is selected via user interface, then indoor fan runs at
set speed.
b) If Ti1 ≥ 5ºC for 2 minutes, then AUX2 is turned on. Indoor fan runs at set speed.
