T10 — REMOTE SPACE TEMPERATURE SENSOR — Sensor T10 (part no. HH51BX006) is an accessory sensor that is remotely mounted in the controlled space and used for space temperature reset. The sensor should be installed as a wall-mounted thermostat would be (in the conditioned space where it will not be subjected to either a cooling or heating source or direct exposure to sunlight, and 4 to 5 ft above the floor). The push button override button is not supported by the ComfortLink™ Controls.

Space temperature sensor wires are to be connected to ter- minals in the unit main control box. The space temperature sensor includes a terminal block (SEN) and a RJ11 female con- nector. The RJ11 connector is used to tap into the Carrier Com- fort Network (CCN) at the sensor.

To connect the space temperature sensor (Fig. 11):

1.Using a 20 AWG (American Wire Gage) twisted pair conductor cable rated for the application, connect 1 wire of the twisted pair to one SEN terminal and con- nect the other wire to the other SEN terminal located under the cover of the space temperature sensor.

2.Connect the other ends of the wires to terminals 5 and 6 on TB5 located in the unit control box.

Units on the CCN can be monitored from the space at the sensor through the RJ11 connector, if desired. To wire the RJ11 connector into the CCN (Fig. 12):

IMPORTANT: The cable selected for the RJ11 connec- tor wiring MUST be identical to the CCN communica- tion bus wire used for the entire network. Refer to table below for acceptable wiring.

1.Cut the CCN wire and strip ends of the red (+), white (ground), and black (–) conductors. (If another wire color scheme is used, strip ends of appropriate wires.)

2.Insert and secure the red (+) wire to terminal 5 of the space temperature sensor terminal block.

3.Insert and secure the white (ground) wire to terminal 4 of the space temperature sensor.

4.Insert and secure the black (–) wire to terminal 2 of the space temperature sensor.

5.Connect the other end of the communication bus cable to the remainder of the CCN communication bus.

Air Conditioner specifications

Carrier Air Conditioners have long been synonymous with reliability and innovation in climate control. Founded by Willis Carrier, the inventor of modern air conditioning, the brand has continuously set industry standards through state-of-the-art technologies and features designed to enhance indoor comfort.

One of the standout features of Carrier air conditioners is their energy efficiency. Many models are equipped with advanced inverter technology, allowing the compressor to adjust its speed based on the cooling demand. This results in decreased energy consumption, which not only reduces utility bills but also lessens the environmental impact. Recognizing the importance of sustainable practices, Carrier has integrated eco-friendly refrigerants into their systems, further promoting energy-efficient operations.

Carrier also emphasizes user comfort through its variable speed systems. These systems maintain consistent temperatures while minimizing temperature fluctuations, ensuring an even distribution of cool air throughout the home. Additionally, many Carrier models come with advanced air filtration systems, designed to capture allergens, dust, and other particulates, thereby improving indoor air quality.

The smart technology featured in Carrier air conditioners plays a key role in modern convenience. Many units are compatible with smart home systems, allowing users to control settings remotely via smartphones or voice-activated devices. With features like programmable thermostats, users can easily set cooling schedules to match their lifestyle, ensuring comfort while maximizing energy savings.

Durability and noise reduction are also central to the Carrier brand. Many models are designed with sound-dampening features, making them some of the quietest units on the market. This is particularly advantageous for residential use, where noise can disrupt daily activities and sleep.

In terms of design, Carrier air conditioners come in various styles and capacities to suit a wide range of spaces, from compact apartment units to large central systems for sprawling homes. Their extensive warranty and service offerings further reinforce Carrier’s commitment to customer satisfaction.

In conclusion, Carrier air conditioners represent a perfect blend of cutting-edge technology, energy efficiency, and user comfort. Their emphasis on sustainability and smart features positions them as a leading choice for homeowners seeking reliable and innovative climate control solutions. Whether for cooling a small room or an entire house, Carrier remains a trusted name in air conditioning.
