3.2.3.4 Function Set-up Description
z Function code 1：Setting temperature selection
The unit can operate according to air temperature or outflow water temperature.
The air temperature or outflow water temperature can be selected as setting
temperature.
Note: Air temperature as setting temperature is ONLY available when Remote Air
Sensor Connection is enabled and Function Code 18 is set as 01.
z Function code 2：Forced operation
Forced Operation includes forced cooling and forced heating operation:
Forced cooling operation should be performed when additional refrigerant charge is
required.
To charge the refrigerant, the unit must run in Cool mode.
Forced cooling should be performed upon the first run（test run）and when out-door
temperature is lower than 10 ℃；
Forced heating should be performed upon the first run（test run）and when out-door
temperature is higher than 35 ℃；
Forced Operation instantly makes the unit working in Cool/Heat mode for 15
minutes.
