The EZ programmer accessory allows the user to quickly transfer the configuration settings from one thermostat to another. This unique accessory allows the installer to copy stored information from a thermostat. The information may be loaded into other thermostats, without the need to manually enter each item. The installer can extract programming data from a thermostat in the shop and upload it to multiple thermostats in the field. The EZ programmer accessory is an easy way to make the same program changes or change the time on multiple thermostats at the same location.
