12.13 Electric Heater Control 1
 Starting condition
o When all condition (1+2+3+4+5+6+7) are fulfilled.
 Operation ON
 Indoor Heating mode
 Thermostat ON
 Temperature different control
Example:
a. When air conditioning is switch ON,
Remote controller setting = 82.4°F (28°C)
Intake air temperature = 78.8°F (26°C)
Temp difference = 82.4°F (28°C) - 78.8°F (26°C) = 3.6°F (2°C)
Heater ON
b. After a while when
Remote controller setting = 82.4°F (28°C)
Intake air temperature = 80.6°F (27°C)
Temp difference = 82.4°F (28°C) - 80.6°F (27°C) = 1.8°F (1°C)
Heater OFF
c. After a while when
Temp difference ≥ 7.2°F (4°C)
Heater ON
 Intake air temperature control
 Evaporator pipe sensor control
 Indoor Fan speed ≥ Lo Fan
 Control content
o Electric heater will be switch ON when all condition for starting condition fulfilled.
o Once Electric heater switched ON, It will operate at least 3 minutes.
