Heat mode with electrical heater as primary heat source
a)
MTV1, MTV2, and AUX2 are always off
b)
If Ti2 ≤ 30ºC (or Ti2 is damaged or disconnected), AND if Tr ≤ Ts-1ºC (or -4ºC if economy contact is activated), heat
operation is activated, electrical heater and AUX1 are turned on. Indoor fan runs at set speed.
c)
If Tr > Ts, then heat operation is terminated, Electrical heater and AUX 1 are turned off. Indoor fan runs at Modbus
310000 setting.
d)
The range of Ts is 16-30 ºC
e)
Indoor fan speed can be adjusted to low, medium, high and auto.
Over-heat protection of indoor coil in heat mode
a)
If Ti1 ≥ 75 ºC, then MTV1, AUX2 and EH are turned off, indoor fan runs at high speed, even in standby mode.
b)
If Ti1 < 70 ºC, then unit will maintain its original state.
c)
If the indoor coil temperature sensor is damaged, the protection mode will be overridden and the pre-heat and post-heat
set times will be used instead.
PRE-HEAT
Pre-heat without electrical heater
a)
If Ti1 < 36ºC [or < 28ºC is selected by DIPB-S2 position SW4], then MTV1 and AUX1 are turned on, indoor fan runs at
Modbus 310000 setting.
b)
If Ti1 ≥ 38ºC [or ≥ 30ºC is selected by DIPB-S2 position SW4], then MTV1 and AUX1 are turned on, indoor fan runs at set
speed.
c)
If the indoor coil temperature sensor is damaged, then the pre-heat time is set for 2 minutes. Indoor fan runs at set
speed.
Pre-heat with electrical heater
a)
If the indoor fan speed ≥ at Modbus 310000 setting, then the electrical heater will turn on.
POST-HEAT
Post-heat without electrical heater
a)
If Ti1 ≥ 38ºC, then MTV1 and AUX 1 are OFF, then indoor fan continues to run at set speed.
b)
If 36ºC ≤ Ti1 ≤ 38ºC, then MTV1 and AUX1 are turned off. Then indoor fan maintains its original state.
c)
If Ti1 < 36ºC, then MTV1 and AUX1 are turned OFF. Then indoor fan is turned OFF.
d)
If the indoor coil temperature sensor is damaged, then the post-heat time is set for 3 minutes.
Post-heat with electrical heater
a)
Indoor fan will run at Modbus 310000 setting before the unit turns off for 20 seconds.
Over-heat protection of indoor coil in post-heat
a)
If Ti1 ≥ 75ºC, then MTV1 and AUX1 are turned off. Indoor fan remains on and runs at high speed.
b)
If Ti1 < 70ºC, then MTV1 and AUX1 are turned on. Indoor fan remains on and runs at set speed.
c)
If the indoor coil temperature sensor is damaged, then the protection mode will be overridden and the unit will work
according to the pre-heat and post-heat program.
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.
