Ventilation Kit includes Titan Thermostat (UT32), 4″ 24V Powered Open / Spring Closed Damper, and 20VA Transformer. The UT32-VK ventilation kit is a low-cost combination of the Titan thermostat and supply air ventilation control designed to meet ASHRAE 62.2 and other ventilation requirements in both single and multifamily new construction applications. This highly universal control, which allows for a fresh air damper to be wired directly to the thermostat, eliminates the need for an additional control panel.
