Introduction
● Smart Thermostat is a wireless thermostat with the capability of being controlled by a mobile application.
● It has the ability of being used in both residential and commercial settings.
● Controls all Heating, Ventilation, and Air Conditioning (HVAC) settings both manually and remotely
● Communicates with the mobile app via internet anywhere in the world

Problem
● Most heating, ventilation, and air conditioning (HVAC) thermostats do not give users the ability of programming weekly schedules or complete wireless control via mobile application.
● Our market is for users that are frequently out of home or office and want to save money on monthly electricity cost by only heating or cooling the home when needed.

Technical Constraints
Constraint Description
Internet Connection
Must be able to receive and process controls from a mobile device over any internet accessible area.
Temperature Range and Accuracy
Must accurately adjust the temperature ±0.5°C over a range of 10°C (50°F) to 37.8°C (100°F)
System Voltage Must operate at 24 VAC supplied from the HVAC system
Weekly Scheduling
Must be able to accept users’ weekly schedules and adjust HVAC settings accordingly.
Mobile Control Must have a free mobile application that can be downloaded on a mobile smart device and control all functions of the HVAC system.

Testing Procedure
● Test for temperature range and accuracy. Must measure accurately ±0.5°C from 10°C to 40°C
● Test for internet connection and mobile communication from various locations
● Test the weekly scheduling and manual override ability
● Test for constant power supply from the HVAC system to Smart Thermostat

Potential Problems
● Failure to communicate at any distance where internet connection is avaliable
● Failure to maintain the weekly schedules down to the hour
● Failure to accurately operate the HVAC system at the desired temperature
