Solar-Powered Thermostat

Oct. 16, 2018
Titus' solar thermostat offers a three-week power storage and needs no building power.

The Helios variable air volume (VAV) diffuser has a solar-powered, wireless control that harnesses the power of indoor lighting or direct sunlight to personalize temperature control.


The wireless control includes a solar powered wall sensor and plug-in postmaster, allowing Helios to be managed with quick and easy pushbutton pairing. One thermostat control can power up to 15 diffusers in a single zone. Pairing does not require line-of-site between the control and the diffusers, allowing greater flexibility in placement and design. Helios VAV diffuser and wireless control features a solar cell that doesn’t require an outside power source, decreasing installation costs and improving energy efficiency.


The wireless control gives occupants digital accuracy to customize their comfort. Each diffuser in a zone can be individually controlled to provide the perfect level of comfort, improving employee efficiency as well as putting an end to office thermostat wars.


The Helios VAV diffuser is the HVAC industry’s first digital diffuser that is powered by both ambient light and direct sunlight. Helios VAV diffuser and wireless control are ideal for office, healthcare and education applications. Both can be used as retrofit installations.
