This programmable low voltage thermostat is suitable for use with
forced hot air and hot water heating systems with central air conditioning. The feature making this thermostat particularly unique is that it will automatically switch between heating and cooling as
needed. You may program up to four settings per day, with each day
being programmed differently if desired. It will retain the settings in memory even during a power outage, eliminating the need to re-program the thermostat. 1.5 amp resistive load at 30 volts. 0.5 amp inductive load at 30 volts. Suitable for 2, 3, 4 or 5 wire applications. 3.8" (97 mm) wide x 4.9" (125.5 mm) high x 1.0" (26 mm) deep.
