Venstar Phone Controlled* Thermostat: T1900 (Residential)

*Note: Venstar Phone Controlled* Thermostat: T1900 (Residential) requires the use of Venstar Comfort Call Phone Controller (ACC0433) (not included).

Overview

Save energy by running your heater and air conditioning only when you're at home. The 7-Day Programmable Digital Phone Controlled Thermostat allows you to program the heater to turn on half an hour before you normally arrive home or run the air conditioning only when necessary to keep the pets cool while you're at work. You can even schedule different programs for different days of the week, ideal for people whose schedules vary or who are home on the weekends. Compatible with heat/cool, heat pump, and dual-fuel systems, the 7-Day Programmable Digital Phone Controlled Thermostat will control up to three heat stages as well as two cool stages.
