Product Description

The Laars LAARS-E2078500 is a double-pole single-throw (DPST) time delay relay designed for use in Laars heating systems. This relay controls the timed sequencing of electrical circuits within the unit, allowing specific components to energize or de-energize after a set delay period. It is an OEM-style replacement part intended for installation by licensed HVAC technicians or qualified heating system service professionals. The LAARS-E2078500 supersedes the previous part number E2075700, making it the current factory-approved replacement for that earlier component.

This time delay relay is used in Laars TL80-199 heating units. It fits into the unit's control circuit and supports proper sequencing during heating cycles. Installation is appropriate for residential or light commercial applications where Laars heating systems are deployed. Service technicians replacing a failed relay or performing a control system upgrade should confirm the superseded part number E2075700 in the existing unit before installing this replacement.
