This easy-to-operate 1-Week Programmable Thermostat helps make your home comfortable exactly when you want it. Programmable for one week, it lets you customize your schedule with four options – 'wake', 'leave', 'return', and 'sleep' – for precise temperature control and added comfort. Simple step-by-step instructions included with the thermostat make DIY installation easy.
