Hawk 1000 Section 1 — General
Part No. 750-366 1-3
1.2 System Description
The HAWK 1000 Boiler Control System provides boiler firing rate control to maintain steam pressure (or hot
water supply temperature) on set point. Final control element(s) are modulated via Modbus communications
network to insure that the optimum fuel/ air ratio is maintained throughout the firing range.
The Hawk 1000 supports two fuel types. Each fuel type can be fired in one of three possible methods: single-
point combustion, parallel combustion, and LOW-HIGH-LOW (fuel 2 only). In parallel systems, the Hawk
1000 can also control a flue gas recirculation (FGR) damper.
The Hawk 1000 can be monitored by Building/ Plant Automation Systems via an optional CB-PT protocol
translator. EtherNet/ Internet communication also enables remote monitoring of the Hawk 1000 Boiler Control
System. (Additional software and/or hardware required).
The HAWK 1000 may be used on most types of steam and hot water boilers, including firetube, industrial
watertube, and commercial watertube. In addition to installation on new boilers, the HAWK 1000 can be
added as a retrofit to existing boilers. Call your local authorized Cleaver-Brooks representative for details.
