Digital Thermostatic Mixing Valve for Commercial Hot Water Systems
Uncontrolled hot water temperatures cause scalding injuries and create conditions for waterborne bacterial growth. A digital thermostatic mixing valve blends hot and cold supplies using electronic actuation and multi-point sensing, holding outlet temperatures within a safe, consistent range at every point of use.
A digital thermostatic mixing valve ensures water temperature ±2°F, ideal for HVAC and commercial use. Features touchscreen, IoT control, energy-saving, and safety. We supply the full Watts digital mixing valve IntelliStation range standalone, IoT-enabled, and factory pre-piped configurations across multiple pipe sizes.
At Dutco Tennant LLC, we source mixing valves and plumbing flow control solutions from established international manufacturers for commercial, healthcare, and infrastructure projects across the UAE and GCC, covering all water mixing valve needs in the region's most demanding applications.
Built for Reliable Hot Water Control
- Connects the watts mixing valve to building automation systems via native BACnet and Modbus protocols for centralised remote monitoring
- Self-commissioning on-site setup requires no factory pre-programming, specialist laptop, or additional configuration software
- Full-colour LED touchscreen allows direct temperature adjustment without third-party tools or service visits
- Programmable setback schedules lower recirculation loop temperatures during unoccupied periods, reducing energy consumption
- Lead-free construction across all IntelliStation variants meets potable water compliance requirements in commercial installations
Technical Capabilities Across the Range
- Sanitisation Mode: Automated high-temperature thermal eradication cycles mitigate Legionella risk, with every completed cycle logged for compliance audit purposes
- IoT Connectivity: Watts Nexa and OnSite apps enable remote temperature adjustment, scheduling, and multi-site valve monitoring from a single interface
- Cross-Flow Protection: Inlet watts check valve protection prevents backflow between hot and cold supply lines during pressure variations
- Energy Scheduling: Occupancy-based setback programming reduces water heating demand during off-peak hours, cutting utility costs across large facilities
- Recirculation Control: Integrated pump control keeps tempered water circulating through the distribution loop, preventing stagnation between draw-off points

FAQ
Is the IntelliStation suitable for retrofit projects or new installations only?
Compact configurations and flexible pipe size options make it suitable for both new installations and retrofit into existing hot water systems with minimal civil modification.
Can multiple IntelliStation units be monitored from a single interface?
Yes, the Nexa and Watts OnSite apps support multi-site valve management, allowing multiple units across different buildings to be monitored from one dashboard.
What happens if the hot water supply temperature drops below the setpoint?
The valve closes the cold water port progressively to compensate, maintaining the closest achievable outlet temperature until normal supply conditions are restored.
Is the IntelliStation compatible with solar or heat pump water heating systems?
Yes, the valve accepts hot water from any supply source, including solar thermal and heat pump systems, provided inlet temperatures fall within the specified operating range.
How is the mixed outlet temperature adjusted after initial commissioning?
Outlet temperature can be adjusted directly through the touchscreen controller or remotely via the Nexa app without requiring a service visit or system shutdown.
What is the expected service life of the valve in a Gulf climate?
Lead-free construction and corrosion-resistant internal components are suited to high-temperature, high-humidity operating conditions common across UAE and GCC installations.
