Overview
The AQ775A Aquatrol Outdoor Temperature Compensator for injection pumps provides full outdoor reset through variable speed control of an injection pump. By using the optional boiler return sensor, both controls can provide boiler shock or flue gas condensation protection.

This product is obsolete. It can be purchased while supply lasts, or you can look for a replacement in the cross-reference.

Features

• Automatic reset curve calculation. • Adjustable settings for mixing maximum temperature, boiler minimum return temperature and outdoor air low (design) temperature. • Optional 70 F (21 C) Warm Weather Shut Down (WWSD) to prevent summer heating operation. • Optional Setpoint Control mode for constant loop temperature control. • Replacement circulator relay common to other Honeywell replacement controls. • Supply, outdoor and return sensors included. • Long life DC relay drive control technology. • Troubleshooting LEDs. • Push-to-test button. • Full size screw terminals. • 120 Vac modulating output to variable speed circulator. • A standard circulator can be used as an injection circulator. • Warm weather mixing injection circulator exercise functions.
