Aprilaire 6020 - User Manual

SAFETY INSTRUCTIONS
Read this entire installation manual before beginning installation of the Aprilaire 6000 Series Zone Control System. For questions call Aprilaire
customer support at (800) 334-6011 or visit AprilairePartners.com.
WARNING
1. 120 volts may cause serious injury from electrical shock. Leave power disconnected until installation is complete.
2. The system is designed for indoor use only. Do not expose any of the components to moisture.
WARNING
1. Turn o the system power before removing or installing any wires into the terminals of any component of the system. Wiring with a live
circuit can lead to electrical shorts that can damage components.
2. Installation must be done in accordance with all applicable codes.
3. Installer should touch a grounded metal object before handling the components of the system. This will prevent any static discharge that
may cause damage.
4. A 6000 Series Zone Control System may not control temperature properly unless the heating and cooling system is properly sized and
balanced.
5. Insucient air flow or excessive temperatures through the heating and cooling system could result in equipment damage. Refer to the
manufacturer’s recommendations for minimum safe airflow and temperature requirements.
6. Do not mount the 6000 Series Control or Sensors on any exterior wall or equipment supply ductwork.
7. Do not install the system components where temperatures exceed 158°F (70°C) or are below 32°F (0°C), non-condensing.
8. Improper system installation could cause water damage from frozen pipes. Check system operation after installation.

4. Maintenance Features

The Aprilaire 6000 Series Zone Control System is a comprehensive solution for managing indoor climate and air quality across multiple zones. It is designed for models 6010, 6015, 6020, 6025, 6030, 6035, 6040, 6045, and 6045M.

Function Description

The system provides precise temperature control, indoor air quality management, and zone-specific climate adjustments. It integrates heating, cooling, humidification, dehumidification, air cleaning, and ventilation functionalities. The system prioritizes heating calls and manages opposing heating/cooling calls with a 20-minute changeover time limit. It also incorporates discharge air temperature (DAT) sensor limits to prevent equipment damage from overheating or freezing. Emergency Heat mode is available for heat pump systems, locking out the heat pump and utilizing auxiliary heat. Fan operation can be initiated by any zone, closing dampers for non-calling zones.
