Lochinvar & A.O. Smith 100167769 Control Board THPU32HP7Y A mid-point ground transformer balances

A mid-point ground transformer balances the electrical stress across the secondary windings

This 24 volt HVAC transformer is the specified choice for maintaining the integrity of the secondary control loop in 208-230V single-phase systems

this control is primarily intended for medium and low-pressure refrigerants like R-134A or R-22 legacy systems

This 24V heat sequencer features four distinct timings that provide a staggered start-up and shut-down sequence (1-160 seconds)

always verify the 200°F–400°F temperature range against your equipment's specific requirements
