Lightstat's i-stat, the Wireless Internet Thermostat, puts you in complete control over the temperatures in your stores. A friendly interactive web site makes it easy to set up and maintain full seven-day programs from any computer with Internet access. The i-stat replaces your existing thermostats wire for wire. Programs are transmitted wirelessly to the thermostat's internal one-way paging receiver so there's no need for phone lines or special hardware. Installation is a snap for your own local contractor. Just wire it up, call a toll-free number for activation, and you're all set. Like our other commercial thermostats, the i-stat supports two stages of heating and cooling and is gas, electric, and heat pump compatible. Optional remote temperature sensor lets you locate the thermostat away from high traffic areas. Local temperature adjustment can be disabled or limited to 3 degrees up or down to prevent employee abuse and equipment damage. Built-in wireless paging technology allows for remote program updates over the air, any time.
