Della OS and UEI TIDE Touch: Portfolio Wide HVAC Control for Multifamily

The short answer: Universal Electronics Inc. (NASDAQ: UEIC) and Della offer a joint smart HVAC solution for multifamily communities. UEI's TIDE Touch thermostat provides the hardware, and Della OS provides portfolio wide control: automated vacant unit temperature profiles, rules based automation, remote control of common areas, and operator overrides kept separate from resident controls. The two companies announced it on Business Wire on September 15, 2026.

The problem: thermostats that run alone

In most apartment communities, each thermostat is managed on its own. Vacant units heat and cool an empty space during turnover, common areas run on fixed schedules, and site teams find a failing system only when a resident calls. A thermostat can be excellent and still live in isolation.

What TIDE Touch brings

• A full color touchscreen for residents
• A built in Zigbee coordinator
• Compatibility with conventional HVAC, PTACs and fan coils, so it fits most apartment systems

What Della OS adds

• Vacant unit profiles. When a lease ends in the PMS, the unit moves to a protective temperature profile automatically, cutting energy waste during turnover.
• Occupied unit settings. Residents control comfort in the Della Resident app; operators keep portfolio wide overrides separate from resident controls.
• Common areas. Clubhouses and shared amenities are controlled remotely on rules, not fixed timers.
• Early warnings. Inefficiencies are flagged before they become maintenance calls.
• One portfolio view. Climate settings across every property, in one place.

What both companies said

UEI's Senior Vice President of Global Sales, Hrag G. Ohannessian, said pairing TIDE Touch with Della's platform gives property managers a repeatable, scalable way to deploy. Adam Hepworth, Della's founder and CEO, said combining UEI's hardware with Della OS turns device connectivity into property intelligence, from thermostat profiles to vacant unit automation.

Who it is for

Owners and operators who want lower turnover energy costs and fewer HVAC surprises across a portfolio, and integrators who want one thermostat they can specify across mixed HVAC systems. It is installed and supported by Della's certified integration partners.
