Operating Controls

The following controls are located on the front of the control box door, under front panel. To obtain access to operating controls, remove the unit front panel as shown on page 2. See Figure 14.

■FAN CYCLE SWITCH — (Not available on RC or RP units.) This allows the fan to operate in two modes:

CON (Continuous) — This setting allows the fan to run continuously, circulating air even when the tem- perature setting has been satisfied. This switch helps to maintain the room temperature closer to the ther- mostat setting. Use this switch position when maxi- mum comfort is desired. This is the factory default setting.

CYC (Cycle) — This setting allows the fan to cycle on and off with the compressor during heating or cooling. The fan stops when the temperature setting is satis- fied. This results in longer unit off-time and wider variations in room temperature and humidity.

■OUTDOOR THERMOSTAT (52CQ and 52PQ HEAT PUMP UNITS ONLY) — If the setscrew is left at the factory setting (in the heat pump position), the unit will operate in the reverse cycle heating mode. See Fig. 14. When the temperature of the outdoor coil reaches 20° F (approximately 35° F outdoor air tem- perature), the compressor will shut down. The electric heater remains on until the temperature of the out- door coil reaches 35° F (approximately 45° F outdoor air temperature); then the electric heater is shut off and the compressor is energized.

To set unit to operate in electric heat mode only, turn the setscrew to the electric heat position. See Fig. 14.

IMPORTANT: If setscrew on standard heat pump unit is set to electric heat mode operation, the com- pressor is disabled for both heating and cooling operations. If setscrew on heat pump unit with wall thermostat control is set to electric heat mode operation, the compressor will be disabled only for heating operation.

OPERATING MODES (See Figures 15

and 16.)

■OUTSIDE AIR — To bring outside air into occupied space, turn the vent handle to the full open position. See Figure 13.

■OFF — The OFF mode terminates unit operation.

■FAN— The FAN mode will circulate air in the space at high speed and at high or low speed for cooling only models.

■HIGH HEAT OR HIGH COOL — Select mode and rotate temperature knob to desired comfort level. This function provides maximum heating or cooling, and is recommended to raise or lower the room temperature quickly.

■LOW HEAT OR LOW COOL — Select mode and rotate temperature knob to desired comfort level. This function provides minimum heating or cooling with maximum dehumidification and quietest operation.

NOTE: 52C and 52P wall thermostat units have a blank plate. See Figure 16.

52P specifications

Carrier Access 52P is a powerful networking solution designed for service providers and enterprises needing reliable, high-speed connectivity. This device plays a vital role in the ever-evolving landscape of telecommunications, offering advanced features that accommodate various network configurations.

One of the main features of the Carrier Access 52P is its support for multiple WAN technologies. This device can seamlessly integrate with various access technologies, including T1, DSL, and cable. This versatility allows network operators to utilize existing installations while improving overall network efficiency. The ability to combine multiple WAN connections through load balancing maximizes bandwidth and ensures uninterrupted service, which is crucial for businesses that rely heavily on internet connectivity.

The 52P is equipped with intelligent routing capabilities, enabling it to make real-time decisions based on traffic conditions. This Smart Routing feature ensures that critical data is prioritized, enhancing the performance of voice and video applications during peak usage times. The built-in Quality of Service (QoS) mechanisms further support this feature by allocating bandwidth according to user-defined policies, thereby reducing latency and jitter for time-sensitive applications.

Security is another essential aspect of the Carrier Access 52P. The device supports robust security protocols such as IPsec and SSL VPNs, which help protect sensitive data as it traverses the network. Its firewall capabilities provide further defense against unauthorized access, making it an ideal choice for organizations demanding high security levels.

The 52P also boasts a user-friendly interface for configuration and management, allowing network operators to monitor performance and make necessary adjustments with ease. This simplicity is complemented by network management features such as SNMP support and extensive logging capabilities, enabling proactive maintenance and fast troubleshooting.

Furthermore, the Carrier Access 52P is designed for scalability. As demand for bandwidth continues to grow, this device can accommodate future upgrades without requiring a complete system overhaul. This forward-thinking design ensures that businesses can adapt to changing conditions in a cost-effective manner.

In conclusion, the Carrier Access 52P is a robust solution that meets the demands of modern businesses and service providers. With its multi-WAN support, intelligent routing, security features, and user-friendly management tools, it stands out as a reliable choice for ensuring optimal connectivity and performance in dynamic networking environments.
