Action Required

 

 

Cooling Coil Coolant Temp

• Check the chilled water supply temperature.

High

• Verify that the coil fluid coolant temperature high threshold is not set below

 

the normal temperature of your chilled water supply.

 

 

Cooling Coil Coolant Temp

• Check the chilled water supply temperature.

Low

• Verify that the coil fluid coolant temperature low threshold is not set above

 

the normal temperature of your chilled water supply.

 

 

Cooling Coil No Coolant Flow

• Verify the flow from the chilled water supply.

 

• Verify that the chilled water supply isolation valve is open.

 

• Check the operation of the flow switch.

 

• Check the electrical connections to the flow switch.

 

 

Env Humidity High

• Verify that no supply air is fed directly into the return air stream.

 

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the humidity in the room to stabilize after start-up.

 

• Verify that the alarm threshold for the humidity of the environmental sensors

 

(return or remote) is set above the humidify and dehumidify setpoints.

 

• Check the capacity output of the humidifier, and reduce it if required.

 

• Ensure that there is a proper vapor barrier within the conditioned space.

 

• Ensure that the dehumidify mode is enabled.

 

• Verify that the Module is configured and equipped for the dehumidify mode.

 

• Ensure that the dehumidify mode is not disabled because of an active

 

customer input mapped to nonessential lockout.

 

 

Env Humidity Low

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the humidity in the room to stabilize after start-up.

 

• Verify that the alarm threshold for the humidity of the environmental sensors

 

(return or remote) is not above the humidify and dehumidify setpoints.

 

• Ensure that there is a proper vapor barrier within the conditioned space.

 

• Verify that the Module is configured and equipped for the humidify mode.

 

• Ensure that the humidify mode is enabled.

 

• Check the capacity output of the humidifier, and increase it if required.

 

• Ensure that the humidify mode is not disabled because of an active user-

 

defined input mapped to nonessential lockout.

 

 

Env Temperature High

• Check whether the Module is cooling. Look for a temperature differential of

 

15–20°F (8–11°C) between the supply and control (return or remote)

 

temperatures.

 

• Ensure that there is no concentrated heat source in the return air stream of the

 

Module.

 

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the room temperature to stabilize after start-up.

 

• Verify that the temperature alarm threshold for the environmental (return or

 

remote) sensors is above the cool and reheat setpoints.

 

• Ensure that the cooling mode is enabled.

 

• Ensure that the cooling mode is not disabled because of an active customer

 

input mapped to nonessential lockout.

Central Air Conditioning System specifications

American Power Conversion (APC) is renowned for delivering innovative solutions in the realm of power management, but its contributions don't stop there. The company has also made significant advancements in central air conditioning systems. Featuring cutting-edge technologies and energy-efficient designs, their HVAC systems are tailored to meet modern needs while ensuring comfort and sustainability.

One of the standout features of APC central air conditioning systems is their variable speed compressor technology. This advanced system operates at different speeds rather than just cycling on and off. By adjusting the compressor speed to match the cooling demand, these systems optimize energy consumption, leading to lower electricity bills and extended equipment lifespan.

APC's systems also incorporate smart thermostat capabilities, allowing homeowners to monitor and control their air conditioning remotely. Through a mobile app, users can adjust temperature settings, create schedules, and receive maintenance alerts, all of which enhance convenience and efficiency. Furthermore, these smart thermostats can learn user habits over time, automatically adjusting temperature settings to maximize comfort and savings.

Another key characteristic of APC central air conditioning systems is their commitment to eco-friendly refrigerants. Utilizing low global warming potential (GWP) refrigerants, these systems minimize the environmental impact while maintaining high-performance standards. With energy efficiency ratings that often exceed industry benchmarks, APC systems contribute to reduced greenhouse gas emissions and help homeowners adopt sustainable practices.

The design of APC air conditioning units is also noteworthy. They are constructed with durable materials that withstand various weather conditions, ensuring reliability during the hottest months.
