Carrier’s 42TXP direct expansion fan coils are designed to cover low to medium range of air handling requirements. They are compact and ready to fit in the under ceiling application. All units come with solid-state fan controls, 1/2-in. insulation, quiet multi-speed motors, and fully wet coils. Units can accommodate factor supplied field installed heaters from 2 to 4kw. 42TXP are designed for ease of service in under ceiling applications. A carton template for easy location of mounting hardware simplifies installation. Coils are made of double wavy aluminum fins mechanically bonded to copper tubes for superior heat transfer. Direct drive forward curved centrifugal fan attached to 3-speed high efficiency motors. Galvanized sheet metal casing protects against rust and drain pan is polyester powder coated for extra protection. Electrical heater is available option while the control board with the integrated thermostat, remote control and washable Aluminum filters are standard feature. Piping connections position (RH/LH) is optional, and field interchangeable for various applications.

Base Unit Dimensions Notes: - The piping connections drain pan outlet and control box are located on the right hand side facing the airflow as

factory standard. They however can be relocated to the left hand side facing air flow in the field when needed. - Unit should be installed for horizontal discharge only. Suspend horizontally using the factory-provided holes

located at the topside flanges of the unit.

Controller For Ducted Fan Coil Units Features: The controller is used to control air cooled ducted split unit, supports the following functions: - Modes: Cool, Dry, Fan, Heat - Indoor fan speed: Auto, High, Medium, Low - Sleep mode - Compressor protections:

Comp 3 minutes restart protection Indoor coil anti-freeze Room sensor and indoor coil sensor failure monitoring

- Non volatile memory – keep system settings - Programmable On/Off timer - Random restart to minimize voltage dip during compressor first cut in cycle upon power up. Hardware Setting: A 2 way DIP switch is used to configure:

Error Code: If multiple faults happen at the same time, the corresponding error code will be shown one after another

Split System Description 1) On/Off Key: If you press this key, the system will begin operation, Press the key again, and operation stops. (You can hear a receiving beep). If you press this key immediately after turning off the system, the compressor will not operate for 3 minutes to prevent overloading. 2) Operation Mode Selection Key: Toggles the operation mode: Cool, Dry, Heat, or Fan only

3) Fan Speed Selection Key: Toggles the fan speed: Auto, High, Medium, or Low, Note: Fan key is invalid in Dry mode. 4) Temperature Up Key: By pressing Temperature up Key, the setting temperature increases by 1ºC with each press. 5) Temperature Down Key: By pressing temperature down key, the setting temperature decreases by 1ºC with each press. If you set the desired room temperature, then system will maintain the room temperature as set. Upon setting the desired room temperature the system will maintain the room temperature

DIP Switch On Off SW1 Cool Cool-Heat SW2 Water System DX System

Fault Error code Room sensor fault E1 Indoor coil sensor fault E2 Comp fault E4

“COOL” Led Lights on when selecting COOL mode. “DRY” Led Lights on when selecting DRY mode. “HEAT” Led Lights on when selecting Heat mode. “FAN” Led Lights on when selecting FAN mode.

Wired Room Controller (Standard)

Notes: The wired room controller is mounted on the wall and can control all system functions without wireless remote control.

Cool Mode: If the room temperature is higher than the setting, the compressor will automatically turn on provide a cooling effect. On the hand, if the room temperature is lower than the setting, the compressor will automatically turn off to stop cooling operation. If indoor fan is programed to be turned off with comp signal, it will turn off once comp is cut off

Heat Mode: If the room temperature is lower than the setting, the Electric heater will automatically turn on to provide a heating effect. If the room temperature is higher than the setting, the heater will automatically turn off to stop heating operation. If indoor fan is programed to be turned off with heater signal, it will turn off once heater is cut off but subject to 30 sec dispersing remaining heat timing.

Dry Mode: The fan speed runs automatically at low speed and compressor stopping and running is controlled by the difference between room and setting temperatures and by continuous running time. If indoor fan is programed to be turned off with comp signal, it will turn off once comp is cut off

- In Dry mode, the humidity is reduced in the space to be air-conditioned. Fan Mode: There will be no cooling or heating effects; only the fans of indoor unit will run for ventilation at the selected speed (High, Med, and Low). - In COOL or HEAT mode and if AUTO fan speed is selected; Fan speed is automatically selected by controller

according to the difference between setting temperature and room temperature, fan will be continuously running at low speed after setting temperature is achieved.

Notes: a) Temperature setting range is 16ºC to 30ºC or 60ºF to 85ºF. b) Hold down at the same time for about 5 seconds, Temp down and fan keys will toggle the temperature setting from degree C to degree F and vice versa. c) Press any temperature key will flash the current setting temperature for 4 seconds, Should there be no further key press, it will revert to room temperature display. Temperature display range is 0 C to 50 C or 32 F to 99 F. d) Temp keys are invalid in Fan mode.

6) Sleep Key: Press this key to set the SLEEP timer and then the sleep led will light on, to cancel the sleep timer press this key again.

- Sleep function for healthy sleep to control automatically the room temperature and stop automatically the operation of the air conditioner after certain set off time. - Sleep mode is valid in cool or heat mode and invalid in Fan mode.

7) Timer Key: Upon count down of the set hours, the system will switch from OFF to ON or vice-versa. - OFF Timer Function to stop automatically, the air conditioner after certain set OFF time. - ON Timer Function to start automatically, the air conditioner after certain set ON time. * Timer setting is 1 Hour to 24 Hour. The timer led will light on when operating the Timer Function First key press will flash the digital display and Timer Led for 3 seconds.

Notes: a) The digital displays show the number of hours previously set, only the Timer Led flashes. b) Subsequent 3 seconds will show the number of hours previously set; only the timer led flashes. c) Should there be no further key press, it will revert to normal mode. d) Should Timer key is not released timer setting will increase automatically every 0.5-second.

8) Sensor: Receives the remote controller’s signal 9) Display Screen: Displays the set temperature and displays also the TIMER settings when adjusting it. 10) Key Lock Mode: To activate key lock mode, hold down for 3 seconds, temp. Down Key (5) and Mode Key (2).

In key lock mode, all keys are not valid except ON/OFF Key (1) to turn ON/OFF the system. a) Hold down Temp Down and Sleep button for one second to enter into coil temperature display mode.

Press Temp Up key to display indoor coil temperature, High Fan LED flashes. With the same sequence to exit coil temperature display mode. Temperature display range is -9C to 78 ºC.

b) Hold down and FAN buttons for only 1 second to activate the system control parameter setting. Press mode button to go through the desired menu steps (1 to 3) as per the below table. For each setting step press or button to change the setting from 1 to 2, after completing all setting steps hold down for 3 seconds temp down and mode buttons to exit the key lock mode.
