Honeywell 68057 , Inc. Q7999A Controlinks Fuel Air Control Wiring Subbase

SUBBASE FOR R7999'S

The brand new Subbase for R7999 wiring harnesses is a revolutionary platform that provides an innovative solution for HVAC service technicians to simplify the training process and speed installation. For the first time ever, service technicians are able to start with a pre-assembled "sub-unit" that includes the following products: R7000R, R7002V, R7004A/B and R7005A/B, then add their choice of components from the

The Q7999A subbase is designed to work with the existing wiring of R7999's that were sold as a Kit before April 2003. The subbase is a required component if you wish to use the G-pilot fuel air and vapor control system.

The Q7999A R7999 ControLinks Fuel–Air Control wiring subbase is specifically designed for the R7999 series of fuel–air control modules.

The Honeywell 68057, Inc. Q7999A Controlinks Fuel Air Control Wiring Subbase is designed to work with the R7999 Series Gas Vent/Flame Sensor Controller. The subbase allows for easy connection and installation of the flame sensor data cable in multiple spaces. Using the included flame sensor mounting bracket, the subbase provides a convenient design to help with installation in various applications.

The R7999 is a self-contained fuel air controller used for central heating and general ventilation systems. The R7999 receives an HVAC-R (Heating, Ventilating, Air Conditioning – Refrigeration) signal from the thermostat. The R7999 control board contains a microprocessor which requires a 24 VAC power supply to operate an auxiliary blower, an HVAC-R valve solenoid or both functions simultaneously. This subbase is required under the R7999 control board to provide 24 VAC power to operate the auxiliary blower and/or valve solen

The Q7999A Subbase is manufactured with a high quality Aluminium plate and incorporates a 3-stage design that ensures stability of the metering devices.

For use with R7999 ControLogix Plus control devices. Provides four 24 V power controls, two digital inputs, and one contact closure output. Supplied with counterbored panel-mounting bushing for mounting in a knockout on the control device panel, or in a separate panel. For use with CompactLogix L64x/L78x and Logix5000 SX/SXi ControLogix Plus control devices only.
