Case Study: a North American building contractor reduces thermostat installation costs with Promwad's custom wireless controller

a North American building contractor recoups wireless thermostat costs in 2 years with Promwad

Promwad partnered with a North American building contractor to address the high costs of installing wired HVAC thermostats in large apartment buildings. The client faced significant expenses from purchasing and installing commercial wired units and needed a certified, cost-effective alternative to foreign wireless devices that did not meet regional standards.

Promwad developed a proprietary wireless thermostat and gateway system, providing a full turnkey solution from design to pilot manufacturing. They created a unified hardware platform, RTOS-based firmware, and Linux gateway software, utilizing a wireless mesh network. The solution reduced installation time and costs, with a projected two-year payback period. Promwad delivered a certified device, with an initial batch of 1,000 units entering production for the first building.
