It is a commercial programmable thermostat that can be wall-mounted or placed on a bookshelf or office table. Ideal for locations where it is difficult to pull wire. The wireless receiver can be installed in the place of the old thermostat or next to the HVAC equipment. Maintains room temperature by controlling operation of the HVAC system. Separate heating and cooling set points with auto-changeover capability allow occupied and unoccupied programming. Copy command eases programming and saves time when there are similar multiple daily schedules. Energy-saving Smart Fan operates the fan continously during occupied periods and only when heating/cooling is enabled during unoccupied periods. Large Thermoglow display showing room temperature and adjustable dual temperature set points makes vital information easy to read. Flexibility for every application Thermostat can be programmed and configured for use with many different applications including single-stage heating and cooling, 2 stages of heating and cooling, heat pumps, gas or electric heating, and hydronic systems. Flexible configuration allows up to 4 wireless thermostats to be used with one wireless receiver within the same space. The thermostat most recently adjusted retains control of the HVAC equipment. A wireless thermostat can work with up to 16 receivers if needed, for added flexibility. Wireless operation enables thermostat to function anywhere within the space that user specifies within 500 ft of its receivers. Receiver requires hard wiring. Thermostat requires batteries. Reliability for year-round comfort One-degree control accuracy precisely controls the desired space temperature to within 1 degree of user set point. A solid-state, laser-trimmed sensor is used. Service Filter indicator lets maintenance personnel know when the filter needs cleaning or replacing, which aids in equipment efficiency and prolongs equipment life. Safety features for added security and protection Three levels of security and keypad lockout protect against unauthorized usage of the thermostat. Schedules, set points, and thermostat configurations are protected by locking out keypad operation. An easily memorized button sequence unlocks the keypad and allows access to configuration, set point, and scheduling information. Five-minute compressor time guard protects HVAC equipment by preventing compressor short cycling and limits the number of cycles per hour with an adjustable cycle limit. Preoccupancy purge enhances indoor air quality by initiating the fan before the programmed occupancy time. The purge is user-configured from 0 to 3 hours.
