or 7 day programming flexibility: Choose between weekday/weekend or ever-day temperature programming to ensure optimum energy usage.

The Honeywell Home ST9400C is a 2-channel Programmer, designed for control of both heating and stored hot water in complete systems. The heating and hot water programs are completely independent, to allow the system to be operated in the most energy-efficient manner possible. The Honeywell ST9400C lets you choose what times you want the heating to be on, and what temperature it should reach while it is on, allowing you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs. Setting times for central heating and hot water to switch on and off can help reduce your home's energy consumption.
