The Honeywell ST699 24Hr Programmer is a simple user friendly domestic central heating programmer allowing the user to set different times for the day that will be the same every day of the week. The ST699 24Hr Programmer can be used as a replacement for an existing programmer on gravity primary and fully pumped central heating systems. The front panel of the ST699 24Hr Programmer can be fitted to the same back plate as the existing programmer making installation quicker and easier. Setting the timer on the Honeywell ST699 24Hr Programmer is straightforward simply using the top slider switch and the [+] and [-] buttons.
