RobertshawÂ® programmable thermostats, Model 9901i, Model 9915i, and Model 9920i, are for the light commercial sector and feature integrated air control that enables building operators to meet the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) indoor air quality standards for commercial buildings, the company states. The fresh air control feature can operate during an occupancy cycle, says the manufacturer. The integrated contractor identification feature allows the contractor's name and telephone number to be entered into a special menu, which can help the contractor stay top of mind with building operators when the need arises to maintain or service the HVAC systems, says the company. Other features include bilingual (English or Spanish) display flexibility and menu-driven programming.
