FAQ

Q: Can this module work with non-Honeywell systems? A: The module is primarily designed for Honeywell TMR Series systems; integration with third-party controllers may require custom interfacing.

Q: How does the TMR architecture improve reliability? A: TMR duplicates the output channels three times and compares results to detect failures, allowing uninterrupted operation even if one channel fails.

Q: Are there compatible input modules for a complete control loop? A: Yes, Honeywell MU-PDIY22 and other TMR digital input modules can be paired to form a full redundant control loop.
