SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Follow all local electrical codes during installation. All wiring must conform to local and national electrical codes. Improper wiring or installation may damage thermostat.

Recognize safety information. This is the safety-alert symbol . When you see this symbol on the equipment and in the instruction manual, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING, and CAUTION.

These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which

could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

INTRODUCTION

The Base Series thermostat is an electronic 24VAC, non-programmable, manual changeover wall mount thermostat. This thermostat uses a single setpoint to maintain and control room temperature in both the heating and air conditioning modes. The thermostat is designed to maintain +/- 2_F accuracy. No batteries are required; temperature, fan, mode, and installer configuration settings are preserved with power off.

INSTALLATION CONSIDERATIONS

Air Conditioner Model

TB-NAC, Base Series Model air conditioner thermostat, may be wired with or without connecting a common wire between the indoor equipment and the thermostat. However, it is recommended to use a common wire whenever possible. Without a common wire this thermostat becomes “power stealing.” This means it will need to steal a small amount of power from the equipment to which it is connected.

NOTE: Not all HVAC equipment is compatible with power stealing type thermostats. All Carrier equipment is directly compatible with this thermostat except the Thermostat Conversion Kit, Part #TSTATXXCNV10. For all non-Carrier equipment, consult the system equipment Installation Instructions before applying this thermostat in a power stealing manner.

Heat Pump Model

TB-NHP, Base Series Model heat pump thermostat, is compatible with all Carrier heat pump systems. It is NOT power stealing and MUST have both the R and C terminals connected to operate properly. This thermostat uses a green LED to indicate auxiliary heat and emergency heat operation.

INSTALLATION

Step 1 — Thermostat Location

Thermostat should be mounted:

SApproximately 5 ft (1.5m) from floor.

SClose to or in a frequently used room, preferably on an inside partitioning wall.

SOn a section of wall without pipes or duct work. Thermostat should NOT be mounted:

SClose to a window, on an outside wall, or next to a door leading to the outside.

SExposed to direct light and heat from the sun, a lamp, fireplace, or other heat-radiating object which may cause a false reading.

TB-NAC, TB-NHP specifications

Carrier TB-NHP and TB-NAC units are advanced commercial air conditioning systems designed to deliver exceptional comfort and efficiency in a variety of environments. These models exemplify Carrier's commitment to innovation, performance, and sustainability in HVAC technology.

The TB-NHP model is specifically engineered for high-performance needs, making it ideal for large commercial spaces. One of its standout features is the advanced inverter technology which enables the unit to adjust its cooling capacity based on real-time demand. This not only enhances energy efficiency but also provides consistent temperature control, ensuring a comfortable indoor environment.

In contrast, the TB-NAC model excels in providing precise temperature control and energy savings for smaller spaces. This model incorporates a powerful, compact design suited for environments where space is a premium. The TB-NAC utilizes scroll compressor technology, leading to quieter operation and improved efficiency, making it ideal for residential buildings or small commercial applications.

Both models feature Carrier's innovative EcoWise refrigerants that not only comply with global environmental standards but also support the reduction of greenhouse gas emissions. This is particularly important in today's climate-conscious marketplace where sustainability is a key consideration for building owners and operators.

Reliability is another hallmark of the TB-NHP and TB-NAC series. Engineered with rugged components and tested to withstand harsh environments, these units promise longevity and reduced maintenance costs. They are also equipped with smart controls that can be integrated into building management systems, allowing for remote monitoring and diagnostics, which facilitate proactive maintenance and enhance operational efficiency.

The TB-NHP and TB-NAC units are not only valued for their advanced technology and reliability but also for their quiet operation. Low noise levels ensure that these air conditioning systems do not disrupt the working or living environment, making them a preferred choice in noise-sensitive areas.

In summary, Carrier's TB-NHP and TB-NAC models stand out in the HVAC market due to their cutting-edge technology, energy efficiency, and durability. These systems are a testament to Carrier's dedication to providing innovative solutions that meet the complexities of modern commercial and residential climate control needs.
