A standard feature of the Islandaire electronic control
system is the ‘Low Temperature Protection’ option. If an
indoor temperature of 55 °F (or lower) is detected, the
heat cycle will automatically activate (even if the unit
is in the OFF position). While the ‘Low Temperature
Protection’ feature is activated, the letters ‘LO’ will be
displayed. The heat cycle will continue until the room
temperature reaches 60 °F, at which time the unit will
satisfy and shut down. All control functions will be
locked-out while ‘LO’ is displayed.
Note: Disconnecting the power supply to the unit is
the only way to interrupt unit function while the ‘Low
Temperature Protection’ feature is activated. If desired,
this feature may be disabled by your qualified service
provider.
