Resideo AM101R-US-1 Valve

The Resideo AM101R-US-1 is a lead-free thermostatic mixing valve designed for high-performance temperature control in domestic water and radiant heating systems. Featuring 3/4 inch Union Sweat connections, this valve provides a stable mixing temperature range of 70°F to 180°F (21°C to 82°C). As a direct replacement for 0204033 and 1170-US-M1-3/4, it simplifies retrofitting in existing mechanical rooms. The AM101R-US-1 utilizes a Teflon-coated shuttle to resist mineral buildup, ensuring long-term scald protection and consistent water temperature regulation even in hard water conditions. With a maximum pressure rating of 125 psi and a high-flow CV rating, this proportioning valve maintains accurate output ±3°F. It is engineered for professional contractors who require a reliable anti-scald device that meets ASSE 1017 requirements for point-of-source applications. Its robust construction ensures it handles high-temperature spikes from the heat source without drifting.

Key Benefits

• Broad Temperature Range: Adjustable setpoints from 70°F to 180°F make it suitable for both radiant floor heating and domestic hot water.
• Direct Cross-Reference: Seamlessly replaces Watts 1170-US-M1-3/4 and 0204033 models without piping reconfiguration.
• Hard Water Resistance: Internal components feature Teflon coating to prevent scale accumulation and mechanical binding.
• High Flow Capacity: Optimized internal geometry provides 3.9 Cv, minimizing pressure drop across the mixing valve plumbing.
• Lockable Handwheel: Includes a tamper-resistant mechanism to lock the temperature setting and prevent unauthorized adjustments.

Common Questions

What is the maximum inlet temperature allowed for the Resideo AM101R-US-1?
This valve is designed to handle constant hot water supply temperatures up to 212°F (100°C), making it compatible with high-recovery boilers and solar thermal systems.

Can this valve be used for point-of-use applications like a single faucet?
While highly accurate, this model is specifically an ASSE 1017 mixing valve intended for "master" mixing at the water heater or mechanical manifold rather than point-of-use protection (ASSE 1070).

Does the AM101R-US-1 include integrated check valves?
Yes, this professional-grade Honeywell Home AM1 series valve includes built-in check valves on both the hot and cold inlets to prevent thermal siphoning and cross-flow.
