How to set humidity and remote sensor
To set the humidity and remote sensor on the Carrier Connect 33CONNECTSTAT43:
1. Remote Sensor:
- Set REMOTE SENSOR to INDOOR or AVERAGE to enable remote temperature readings.
- The thermostat will display REMOTE SENSOR HIGH if the remote temperature exceeds 122°F.
- It will display REMOTE SENSOR LOW if the remote temperature is 0°F.
2. Humidity Settings:
- Humidification Output: Select an available output (O/B, Y3, or W2) for humidifier control.
- Dehumidification Output: Select an available output (O/B, Y3, or W2) for dehumidifier (Humidi-MiZer™) control.
- Dehumidify Function: If DEHUMIDIFY = YES, the cooling setpoint will adjust automatically based on humidity levels.
- If using humidity temperature as a backup sensor, the thermostat will display HUM TEMP SENSOR HIGH if the temperature exceeds 122°F or HUM TEMP SENSOR LOW if the temperature is 0°F.
- Humidity Range Alerts: The thermostat displays HUMIDITY RANGE HIGH if humidity exceeds 90% and HUMIDITY RANGE LOW if it is below 10%.
- Hum Sensor Failure: If the humidity sensor times out, reads above 99%, or is 0%, an error will be displayed.
Ensure that the outputs selected for humidification and dehumidification are not already assigned to other functions.
