5.1.3 Demoisture mode.
* temperature control range: 61°F---86°F
* temperature difference:
34°F
Control feature: send the demoisture signal to the outdoor system.
When Tr>Ts+36°F, the compressor will be turned on, the indoor fan will operate at the set speed.
When Tr is between the Ts and Ts+36°F, the outdoor system will operate at the high demoisture
frequency for 10 minutes and then at the low demoisture mode for six minutes. The indoor fan will
operate at low speed.
When Tr< Ts, the outsystem will be stopped, the indoor fan will be stopped for 3 minutes and then
turned to the low speed option.
All the frequency converses have a
34°F difference.
* Wind speed control: Automatic:
When Tr≥ Ts+ 41°F , high speed.
When Ts+37°F
Tr< Ts+41°F , medium speed.
When Ts+36°F
Tr< Ts+37°F , low speed.
When Tr<Ts+36°F, light speed.
If the outdoor fan stopped, the indoor fan will be paused for 3 minutes.
If the outdoor fan stopped for more than 3 minutes and the outdoor system still operates, the system
will be changed into light speed mode.
When the airflow speed has no delay from the high to low switching, the speed should be delayed for
3 minutes (remain at high speed for 3 minutes.) before the next switch.
Manual: When the sensor is off or Tr< Ts+37°F, the manual operation can not be made. (obligatory
automatic operation.)
*Airgate location control: the location for the airgate can be set according to your needs.
*Defrosting function: preventing the frosting on the indoor heat exchanger (when cooling or
demoisture). When the compressor works continuously for 1/6 minutes (adaptable in EEPROM) and
the temperature of the indoor coils has been below zero centigrade for 10 seconds, the compressor
will be stopped and the malfunction will be recorded in the malfunction list. The indoor system will
continue to run. When the temperature of the indoor coil is raised to 45
°F , the compressor will be
restarted again (the prerequirement of 3 minutes’ delay should be satisfied.)
* coil protection (synchronic overheating protection) are installed for the four directions latch
malfunctions when demoisturing.
* timing system on/off function.
* Dormant control functio
n.
5.1.4 Heating operation mode.
* temperature control range: 61°F---86°F
* temperature difference:
34°F
* control feature: the temperature compensation is automatically added and the system will send the
heating signals to the outdoor system.
If Tr
Ts, the outdoor compressor is turned on, the indoor fan will be at the cold air proof mode.
If Tr>Ts+, the outdoor system is turned off, the indoor fan will be at the heat residue sending mode.
If Tr<Ts+, the outdoor system will be turned on again, the indoor fan will be at the cold air proof mode.
