Heil Quaker ICP 1185125 Control

As a seasoned technician, you know that the Heil Quaker ICP 1185125 Control is the backbone of proper economizer operation in light commercial and residential rooftop units. This OEM replacement part is identical to the HH63AW002 and is essentially the Honeywell Jade W7220 economizer controller. When you’re dealing with HVAC economizer troubleshooting, swapping in this board ensures your system meets current Title 24 requirements and ASHRAE 90.1 standards for fault detection and diagnostics (FDD). It is designed to regulate outside air intake, optimizing energy efficiency by utilizing free cooling when outdoor enthalpy or dry bulb conditions are favorable. The board’s logic seamlessly manages the damper actuator, integrating naturally with CO2 sensors for demand-controlled ventilation (DCV). Whether you're field-installing an enthalpy sensor or configuring a 2-speed fan motor, this low voltage control board provides the precise 2-10 Vdc signal needed for reliable Honeywell Sylk-bus communication and overall system protection.

• Direct Cross-Reference: Fully replaces 1185125 and HH63AW002, ensuring exact fit and function without complex field modifications.
• Advanced Diagnostics: Built-in LCD interface provides real-time fault codes and system status, significantly reducing time spent on economizer repair and setup.
• Regulatory Compliance: Pre-programmed to meet strict energy codes including California Title 24 and IECC damper leakage requirements.
• Versatile Compatibility: Supports a wide range of configurations, from single dry bulb changeover to differential enthalpy with S-BUS sensors.
• Robust Construction: Engineered to withstand the thermal stress of rooftop environments, maintaining stable logic control from 24 VAC power inputs.

Is the 1185125 control compatible with multi-speed fans?
Yes, this Jade W7220 based controller is designed to support 1 or 2-speed indoor fan motors, making it a versatile choice for modern ICP Heil Quaker equipment cycles.

Can I use this board for Demand Controlled Ventilation (DCV)?
Absolutely. By adding a 2-10 Vdc CO2 sensor, this board can automatically modulate dampers to maintain indoor air quality while maximizing energy savings.

What does it mean if the board is identical to HH63AW002?
It means you are receiving the factory-authorized replacement typically found in Carrier, Bryant, and Payne units, ensuring the exact firmware and interface needed for economizer system integration.
