Carrier 33WIFISTAT43 Wi-Fi Thermostat Installation Guide
Table 2 — Parameters
PARAMETER NAME/DESCRIPTION
DEFAULT AND RANGE
HEAT EQUIP TYPE — The equipment heating type. If you select GAS HEAT and the COMPRESSOR TYPE for HP, D: Gas Heat
then the defined DUAL FUEL thermostat operation is used for heating.
R: Gas Heat/Electric
HEATING EQUIP STAGES — The number of gas heating stages or E-heating stages in the equipment
D:
1
NOTE: If set to 2, the W2 relay output is not available for optional functions, such as:
R: 1 to 2
-
-
-
Humidifier
Humid-MiZer™/Perfect Humidity™/Hot Gas Reheat dehumidification
Occupancy Output
COMPRESSOR TYPE — The type of the unit's compressor(s)
NOTE: Select HP for the HEAT EQUIP TYPE to define the auxiliary heat type.
D: A/C
R: None,
A/C, HP
COMPRESSOR STAGES — The numbers of compressors
D:
2
NOTES:
R: None,
1 to 3
If COMPRESSOR TYPE is set to HP, the number of stages also defines the number of HP heating stages.
If set to 3, the Y3 relay output is used for the third-stage compressor and the thermostat configuration is limited for the
following:
-
-
-
Humidifier
Humid-MiZer™/Perfect Humidity™/Hot Gas Reheat dehumidification
Occupancy Output
AUTO ALLOWED — Enables and disables the thermostat to automatically switch from heating to cooling to maintain D: Yes
the temperature between the setpoints.
R: Yes/No
PROG OR NON-PROG — Allows the thermostat to operate as a non-programmable (simplified) thermostat or a
programmable thermostat with two or four time periods per day.
D: Prog
R: Prog / Non-Prog
MAX HOLD TIME — The thermostat setpoints cannot be overridden by the user. When the SCHEDULE PAUSED
button is pressed on the SETPOINTS screen (SCHEDULE IS RUNNING), and the user changes the setpoint, the
MAXIMUM TEMPORARY HOLD TIMER is started with this value and displayed in the clock location.
D: 2 hours
R: Off
1 - 6 hours
FAHRENHEIT OR CELSIUS — The temperature scale
D: °F
R: °F / °C
SMART RECOVERY — Transitions the conditioned space from one programmable temperature period to the next with D: 30
1°F increments of the heating setpoint or with 1°F decrements of the cooling setpoint, so that by the time the next
period starts, the setpoints are at the desired temperature. The purpose of the gradual transition is to use less energy
by preventing staging up (because of a higher demand) to higher stages. The transitions occur in a linear fashion over
the smart recovery time period.
R: No, 30, 60, 90 Min
If you start a temporary hold in the middle of a smart recovery, the setpoints of the temporary hold are used.
If a temporary hold is already active during the time that smart recovery would have been started, a smart recovery
does not start.
If the temporary hold ends in the middle of what would have been a smart recovery, the smart recovery starts where it
would have been in the linear progression at the same time as when the temporary hold was not active.
FAN ON WITH W — Supplies a fan output demand as soon as a W1 or W2 output demand is active.
D: Yes
R: Yes/No
REVERSING VALVE — Defines whether the ON state of the reversing valve is used for heating or cooling when
COMPRESSOR TYPE is set to HP.
D: Cool
R: Cool/Heat
When the ON state of the reversing valve is used for cooling, the signal is typically referred to as a O.
When the ON state of the reversing valve is used for heating, the signal is typically referred to as a B demand.
If COMPRESSOR TYPE is set to HP, the thermostat configuration may be limited for the following:
-
-
-
Humidifier
Humid-MiZer™/Perfect Humidity™/Hot Gas Reheat dehumidification
Occupancy Output
SPACE TEMP OFFSET — Calibrates the internal space temperature sensor.
D: 0° F
R: -5° to 5° F
SPACE HUM OFFSET — Calibrates the internal relative humidity sensor.
D: 0° F
R: -9° to 9° F
AUTO CHANGEOVER — The minimum time between switching from heat-to-cool or from cool-to-heat demands,
when in AUTO MODE. The timer begins when the MINIMUM OFF TIMER expires.
D: 30 Min
R: 5, 10, 15, 20, 25, 30 Min
REMOTE SENSOR — Determines whether the remote sensor hardware input is
D: None
R: None
Space
•
•
NONE — Not used
NONE or SPACE — The outdoor temperature is acquired by Wi-Fi through the server, based on the location of the
mobile device used to connect the thermostat to a router, or based on the ISP location, if a computer connects the
thermostat to a router.
Outdoor
Average
Occupancy
Fault Input
SAT
•
OUTDOOR — Senses the outdoor temperature
NOTE: The outdoor temperature is not available if the thermostat is not connected to Wi-Fi or if you do not select
OUTDOOR.
AVERAGE — Space temperature results from averaging the internal and the external sensor
OCCUPANCY — An external source is accessed to determine if the setpoints are Occupied or Unoccupied. When
Normally Open contacts close, the Occupied setpoints are used.
NOTE: When selected, NON-PROG is automatically set and is not displayed in the Installer Settings until this
parameter is changed.
FAULT INPUT — An external source is used to detect a fault, as determined by the attached Economizer.
SAT — A sensor to provide a means of monitoring supply air temperature
NOTE: SAT is a monitor-only point and has no effect on unit operation.
FILTER – Used to detect a dirty filter. Contact closure causes FILTER REMINDER message on home screen

•
NOTE: This selection disables the timed air filter reminder functionality.
SAT TEMP OFFSET — Allows temperature offsets from -5° to 5°.
NOTE: Only available when Remote Sensor Input > SAT is enabled.
D: 0° F
R: -5° to 5° F
(1° increments)
MAX SETPOINT ERROR — Allows a temperature deviation from setpoint of between 2 and 30°, to determine fault
conditions (ID TEMP RANGE HIGH or LOW).
NOTE: This value is added to the cooling setpoint or subtracted from the heating setpoint.
D: 10° F
R: 2° to 30° F
(1° increments)
