Definitions

Heat demand

The space temperature is less than the heat setpoint (HEAT TO setting).

Cool demand

The space temperature is greater than the cool setpoint (COOL TO setting).

Heat demand satisfied

The space temperature is greater than the heat setpoint (HEAT TO setting).

Cool demand satisfied

The space temperature is less than the cool setpoint (COOL TO setting).

What is the Carrier Connect™ 33CONNECTSTAT43FX Thermostat?

Definitions

Heating equipment

If the Y1, W1, or W2 (W2 in electric heat systems only) outputs are energized

when the mode is set to HEAT, EHEAT, or AUTO, operating in Heat, then the

heating equipment is on. When all of these outputs are off, the heating

equipment is off.

Cooling equipment

If the Y1 output is energized when the mode is set to COOL or AUTO operating in

Cool, then the cooling equipment is on. When Y1 is off, the cooling equipment is

off.

Inputs

Power supply

Class II transformer secondary voltage supplied to the thermostat is 18.0 to 30.0 Vac, 50/60 Hz. Voltage is

applied between Rand Cconnector.

Space air temperature

The space air temperature measurement is supplied by an NTC "J" curve (type II) thermistor. The resistance of the

thermistor is 10K ohm nominal at +25°C with an accuracy of ±0.20°C from +15.6°C to +32.2°C (approximately

0.5°F accuracy from 60°F to 90°F).

If the thermistor reading is invalid, the space temperature is measured by the Sensirion SHT21 humidity and

temperature sensor.

Remote temperature sensor

The remote temperature measurement is supplied by a NTC "J" curve (type II) thermistor connected between T and

C. This thermistor is supplied by the installer to use for Space, Outdoor, Supply Air, or an average with the space

air temperature. When used for the space temperature sensor, up to 9 remote space sensors can be averaged (1,

or multiples of 4, or 9). The Tinput allows for remote occupancy override with T55 style sensor.

•If the Occupancy Input installer setting is set to OCCUPIED, when a short in the circuit from 2 up to 5 seconds

in duration is sensed, a change is made from the unoccupied heating and cooling setpoints to the occupied

heating and cooling setpoints for the current time period, for the configured allowable time.

•If the Occupancy Input installer setting is set to UNOCCUPIED, when a short in the circuits sensed for more

than 2 seconds, the occupied heating and cooling setpoints change to the unoccupied heating and cooling

setpoints for the current time period.

•Alternatively, you can use the remote temperature sensor input as a remote occupied/unoccupied selection

as well as an indicator of economizer fault or Filter Reminder.

•Alternatively, Wi-Fi outdoor temperature is available by GPS location services –determined when the

thermostat is installed and registered through a Wi-Fi connection.

What is the Carrier Connect™ 33CONNECTSTAT43FX Thermostat?

Remote humidity sensor (0-10 volt or 4-20 mA)

The remote humidity measurement is calculated from the 0-10 volt or the 4-20 mA signal applied between Hand

C. When the output of the duct sensor is the 4-20 mA signal, a 500 ohm load resistor must be connected between

Hand C.

Space humidity sensor

The humidity is read via synchronous communications from a Sensirion SHT21 Humidity and Temperature Sensor.

The Sensirion humidity is accurate to +/- 2 % relative humidity between 20 and 80 % relative humidity.

Outputs

Connections are made via a compact and robust single pole, “finger friendly” spring-type terminal block. All

outputs have a max rating of 1.25 Amp @ 24 Vac.

Getting to know the user interface

Dormant screen

The dormant screen is displayed when not interacting with the thermostat.

The banner scrolls through date and time, humidity, outdoor air temperature, if configured, and any active faults

or system events. The room temperature is prominently displayed.

There are no buttons on this screen, but the 13 touch locations are active, so when the display is touched, the

thermostat transitions to the LOCK screen, if lockout is enabled, or the home screen, if lockout is disabled.

Home screen

You interact with the thermostat primarily from the Home screen.

The center portion of the screen displays the current space temperature in whole degrees. The default

temperature scale is °F, but can be changed to °C in the Installer settings (page 28).

The top of the screen displays a banner that cycles system information every 3 seconds. To see the scrolling

messages faster than 3 seconds, press the banner area of the screen to advance to the next message.

The icon indicates the current Wi-Fi signal strength by the number of bars. A strong signal has 3 arched bars.

indicates the thermostat is not connected to a router.

Above the space temperature, the current state of occupied or unoccupied displays, unless you have temporarily

overridden the program schedule settings. When overridden, the banner displays PAUSED and shows the time

remaining in the override.
