Notes:
*1:
Always use together with the local remote controller or system controller.
*2: Always register the LM ADAPTER as a system controller when using together with the system controller.
*3: The functions used with the LM ADAPTER are changed. The air conditioner and LOSSNAY cannot be set to interlock with the LM ADAPTER.
Set with the system controller or local remote controller.
*4: Carry out an instruction input at the unit of the lowest address unit in the same group. The instructions to other units are disregarded.
However, a state output is output for every unit. Forced thermostat OFF needs an instruction input for every unit.
*5: Input the same instructions to all the units in the same group.
*6: Make a monitor interval into 1 minute, and when you use both the functions of "local prohibit", and the "forced thermostat OFF", give 25 sets or less.
