the system (HWHP (CAHV))
Operation status (ON/OFF), operation mode, temperature setting, fan mode, and temperature
(Representative, Outdoor, Inlet, Outlet) are displayed.
Operation status of each group in
the system (measurement)
Measurements by the temperature sensor and humidity sensor that are connected to the AI
controller are displayed.
Measurements by the watt-hour meter that is connected to the PI controller are displayed.
Filter sign
Indicates that the filters on the units in a given group is due for cleaning.
Water circuit sign
(Air To Water (PWFY))
Indicates that the circulating water circuit in a given group is due for replacement.
Local operation prohibition
