Concept Drawing: This is only a concept drawing, not an engineered drawing. It is not intended to describe a complete system, nor any particular system. It is up to the

system designer to determine the necessary components for and configuration of the particular system being designed, including additional equipment, isolation relays

(for loads greater than the control’s specified output ratings), and any safety devices which in the judgement of the designer are appropriate, in order to properly size,

configure and design that system and to ensure compliance with building and safety code requirements.

Application A132-1 System Operation: The Pump Sequencer 132 provides stand-by pump operation. Piping Details The lead pump and the stand-by pump are piped in parallel in the system. Pump Demand The Pump Demand is powered continuously. When the 132 is not in warm weather shut down, the control turns on the lead pump to provide flow in the system. All control functions and specifications are listed in the Product Catalog I 000 and Data Brochure D 132.

Application A132-2 System Operation: The Pump Sequencer 132 provides 2-stage pump operation. Piping Details The first stage pump and the second stage pump are piped in parallel in the system. Pump Demand The Pump Demand is powered continuously. When the 132 is not in warm weather shut down, the control turns on the first stage pump to provide flow in the system. 2-Stage Demand When additional flow is required, the pressure differential switch closes and provides power to the 2-Stage Demand.

Application A 132-3 System Operation: The Mixing Control 362 provides full outdoor reset to a mixed zone. The output of the variable speed injection pump is modulated to mix the water temperature to the zone and protect the boiler from flue gas condensation. The boiler operates at the required temperature in order to satisfy the load. The 132 provides stand-by pump operation to the 362. Heat Source Details The heat source can be either a high mass or low mass non-condensing boiler.

Application A132-4 System Operation: The Boiler Control 262 provides partial or full outdoor reset to a boiler zone. The boilers operate at the required temperature in order to satisfy the load. The 132 provides 2-stage pump operation to the 262. Heat Source Details The heat source can be either high mass or low mass non-condensing or low temperature boilers. Piping Details The boilers are piped using parallel primary / secondary in order to provide equal and isolated flow through each boiler.
