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. | L M H |
1VFD SPD | Indicates the current VFD fan speed. Dynamic item. Appears only if '6FAN' is configured as 'VFD FAN'. | 60% 80% 100% |
1ACT OUT | 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'. | HP(O) HP(B) CON RTU |
