WHAT IS A TImer?
General Description
Your  Honeywell  ST9100A  provides  timing  control  for  your  central  heating  system, letting you set ON and OFF periods to suit your own lifestyle. 
The ST9100A does not directly control the temperature but works together with other temperature  controls,  such  as  room  thermostats,  to  control  your  heating  system  in your home.
ST9100A  has  1-day  programming  and  2  on/off  periods  per  day,  making  it  very simple to use.

The Built-in Programmes
The  built-in  programmes  give  you  a  starting  point  that  you  can  personalise  to  your own  requirements.  Your  Installer  should  have  selected  one  and  ticked  the  box alongside it. If there is no tick, the product normally leaves the factory with Profile A installed, but it is a simple matter to select one of the other profiles (see Changing the Installer Parameters, page 12).
