•
(*1) These numbers are expressed as a signed 16-bit value using 2-complement format for negative values.
•
(*2) Only for Heating and Cooling units.
•
(*3) This value is limited by the machine according to their rank.
•
(*4) This parameter informs that the modbus net is in alarm
•
(*5) These parameters show thermostat setting and room temperature, which may be different than those in the unit when using central control
(Thermostat and Room sensor via Modbus)
•
(*6) Access to menu in unit control is blocked
•
(*7) Enable this parameter when using Modbus thermostat
•
(*8) This parameter can only be used if no have installed HITACHI thermostat, only when using Modbus thermostat. Unless the central bit is ena-
bled, so the HITACHI thermostat is used only for setting temperature.
•
(*9) This parameter can only be used if the function is enabled on the LCD.
