Product description

The Modine 4015315 Terminal Board and Time Delay Relay is a critical control component designed to maintain the efficient and safe operation of Modine Hot Dawg (HD) series unit heaters. This integrated board serves as the central wiring hub for the heater's low-voltage and high-voltage connections, streamlining the installation and troubleshooting process. The built-in time delay relay is a key safety feature that manages the blower motor's operation, ensuring that the motor continues to run for a set period (typically 30 to 90 seconds) after the thermostat is satisfied. This post-purge cycle effectively removes residual heat from the heat exchanger, preventing thermal stress and extending the life of the unit. The 4015315 is a direct replacement for older models that used separate terminal boards and relays, providing a more reliable and compact solution. Its design includes clearly labeled terminals and follows the original factory wiring logic, making it a straightforward replacement for models HD30 through HD75.
