FC-15 (Thermo On / Off Differential)
Allows installer setting (field adjustment) of temperature targets. Use
FC-15 in applications to overcome the height difference with indoor
units installed high on the wall or in the ceiling.
Wired (FC-15) controllers can access the thermo on / off differential.
Indoor unit logic must include the function to see the setting codes.
If the function is visible, all sub-settings will display, even if the
indoor unit logic is limited.
• Indoor unit logic limits may prevent all sub-settings from being assignable.
• A sub-setting that isn't recognized by the indoor unit will revert to the default setting.
• The controller will display all sub-settings if the function is available for the indoor unit. Contact an LG Representative for details.
FC-35 (Thermo Off - Indoor Unit Fan
Off)
Turns off the indoor unit fan during Thermo Off. Requires an LG
wired controller to configure / set the installer code.
