Tekmar Controls 132 Pump Sequencer

The Tekmar Controls 132 Pump Sequencer is a device used to control the operation of two pumps in hydronic systems, which are typically encountered in HVAC applications. There are two primary applications for it: staging and standby. By switching back and forth between the two pumps in standby mode, the sequencer makes sure one is always ready to go in case the primary pump breaks down. When the system is in staging mode, the pumps are turned on one after the other to accommodate higher flow or pressure requirements. Additional features of the 132 include pump run intervals that may be adjusted individually, automatic pump exercises to prevent seizing, and potential issue alarms. This aids in maintaining redundancy, efficiency, and system dependability in a variety of HVAC equipment, such as radiant heating systems, boilers, and chillers.
