Carrier SmartView - General Parameters (GENUNIT)

The Main menu provides access to the main control parameters,
including general parameters, inputs and outputs status, etc.
■ To access the menu, press the Main menu button located in
the upper-left part of the Home screen.
■ Specic unit parameters can be accessed by pressing the icon
corresponding to the desired category.
NOTE: The Trendings menu is displayed in form of a graph.
For more information about Trendings, see section 6.26.
CAUTION: Since specic units may not include additional
features, some tables may contain parameters that cannot
be congured for a given unit.

Name Status Unit
Displayed text* Description
CTRL_TYP 0 to 2 Local=0 Net.=1 Remote=2
Operating mode:
0 = Local
1 = Network
2 = Remote
STATUS Run Status
Unit running status: Off, Stopping, Delay, Running, Ready,
Override, Tripout, Test, Runtest
CHIL_S_S disable/enable Net.: Cmd Start/Stop
Unit start/stop via Network: When the unit is in Network mode,
start/stop command can be forced
CHIL_OCC no/yes Net.: Cmd Occupied
Unit time schedule via Network: When the unit is in Network mode,
the forced value can be used instead of the real occupancy state
min_left - min Minutes Left for Start Minutes before the unit start-up
HEATCOOL Heat/Cool status Heating/cooling status
HC_SEL 0 to 2 Heat/Cool Select Heating/cooling selection
0=Cool. 1=Heat. 2=Auto
0 = Cooling
1 = Heating
2 = Automatic heating/cooling control
SP_SEL 0 to 2 Setpoint Select Setpoint selection
0=Auto. 1=Spt1. 2=Spt2
0 = Automatic setpoint selection
1 = Setpoint 1 (active during occupied period)
2 = Setpoint 2 (active during unoccupied period)
SP_OCC no/yes Setpoint Occupied?
Setpoint status:
0 (no) = Unoccupied
1 (yes) = Occupied
CAP_T Unit Total Capacity Total unit capacity
CAPA_T Cir A Total Capacity Total capacity, circuit A
CAPB_T Cir B Total Capacity Total capacity, circuit B
SP Current setpoint Current setpoint
CTRL_PNT
-20 to 67
-4 to 153
°C

Control Point Control point: Water temperature that the unit must produce
CTRL_WT
-20 to 67
-4 to 153
°C
°F
Control Water Temp Controlled water temperature
OAT - °C / °F Outdoor Air Temp Outdoor air temperature
EMSTOP disable/enable Emergency Stop
Emergency stop: Used to stop the unit regardless of its active
operating type
DEM_LIM 0 to 100 % Active Demand Limit Val
Active demand limit value: When the unit is Network mode, the
minimum value will be used compared to the status of the external
limit switch contact and the demand limit switch setpoint
LAG_LIM 0 to 100 % Lag Capacity Limit Value
Lag capacity limit value: Value that is forced by the master chiller
(master/slave assembly)
* Depends on the selected language (English by default)
Temperatures – TEMP
Name Status Unit Displayed text* Description
EWT - °C / °F Entering Fluid Temp Evaporator entering water temperature: Used for capacity control
LWT - °C / °F Leaving Fluid Temp Evaporator leaving water temperature: Used for capacity control
OAT - °C / °F Outdoor Air Temp
Outdoor air temperature: Used to determine a number of control
mechanisms such as heat/cool changeover, water exchanger
heater operation, defrost cycle, free cooling option, and more
