1FREECOOL

Indicates if the system can use outdoor air for free cooling.

YES

NO

1ECON ENAB

Indicates if outdoor air is being used for the 1st stage of cooling.

1OCCUPIED

Indicates if the space is occupied. If you choose 'ALWAYS' for '6OCC ' when configuring I/Os, the parameter value is 'YES'; if you keep the default selection 'T-STAT' for '6OCC ' and the controller receives 24V signal from OCC input, the value is 'YES'. Otherwise, the value is 'NO'.

YES

NO

1MIX AIR LOW

Indicates if the anti-freeze protection function is enabled for a mixed air temperature sensor. If the detected air temperature is lower than the anti-freeze protection setpoint (3FRZ PROT), the parameter value is 'YES'. Otherwise, it is 'NO'.

1MAT PRES

Indicates the present value of the mixed air temperature (MAT) sensor.

Dynamic item. Appears only if 'MAT' or 'AUTO' is selected for '3DIF T LOC' under Advanced Settings.

The corresponding detected value is displayed on the LCD.

1LAT PRES

Indicates the present value of the leaving air temperature (LAT) sensor.

Dynamic item. Appears only if 'LAT' or 'AUTO' is selected for '3DIF T LOC'.

1OAT PRES

Indicates the present value of the outdoor air temperature (OAT) sensor.

Dynamic item. Appears only if an OAT sensor is configured.

1OAE PRES

Indicates the present outdoor air enthalpy (OAE) value.

Dynamic item. Appears only if OAT and OAH sensors are configured.

1OAH PRES

Indicates the present value of the outdoor air relative humidity (OAH) sensor.

Dynamic item. Appears only if an OAH sensor is configured.

1RAT PRES

Indicates the present value of the return air temperature (RAT) sensor.

Dynamic item. Appears only if an RAT sensor is configured.

1RAH PRES

Indicates the present value of the return air relative humidity (RAH) sensor.

Dynamic item. Appears only if an RAH sensor is configured.

1RAE PRES

Indicates the present return air enthalpy (RAE) value.

Dynamic item. Appears only if RAT and RAH sensors are configured.

1CO2 PRES

Indicates the present value of the CO2 sensor.

Dynamic item. Appears only if a CO2 sensor is configured.

1DCV STATUS

Indicates the demand control ventilation (DCV) status.

Dynamic item. Appears only if a CO2 sensor is configured.

Displays ON if the measured CO2 concentration value is above the DCV setpoint and OFF if below the DCV setpoint.

ON

OFF

1FAN SPD LV

Indicates the current fan speed status (low, medium or high). If a one-speed fan is connected and configured, this item is invisible. If a variable-speed fan is configured, the fan speed control logic is the same with 3-speed fan.

Dynamic item. Appears only if '6FAN' is configured as '2SPEED', '3SPEED' or 'VFD FAN' under I/O Configuration.

Indicates current position of damper actuator in V.

The corresponding detected value is displayed on the LCD.

1ACT FB

Indicates feedback signal of damper actuator in V.

1ACT POS

Indicates current position of damper actuator in % Open.

1ACT CNT

Indicates number of times actuator has cycled (1 cycle = 180 degrees of movement in any direction). Resettable via HMI item ' 8ACT CNT RESET' under Enter Running State.

1EQUIP

Indicates the equipment type. If 'HP(O)' or 'HP(B)' is chosen for '6AUX1-I', the parameter value is 'HP(O)' or 'HP(B)' respectively. If neither is chosen, the value is 'CON RTU'.
