Modine 46022 Time Delay Relay Board Kit

Product Description

The MODINE 46022 is a time delay relay board replacement kit designed for Modine heating units. The kit provides the relay board assembly needed to restore proper sequencing and timing control in the heater. Time delay relay boards manage the startup and shutdown sequence of heating elements and blower motors, protecting the system from thermal stress. This kit is intended for installation by qualified HVAC technicians familiar with commercial or industrial unit heater service. The included components allow a complete, code-compliant replacement rather than a partial component swap.

This kit is suited for use in Modine unit heater applications where the original time delay relay board has failed or is showing signs of erratic operation. It is packaged as an OEM-style replacement kit and includes all materials needed for a full installation, including a new wiring decal and installer's guide. Technicians who need only the relay board without the supplemental materials can source the board separately under Modine part number 5H78126-1.
