WHAT IS A TImer?
General Description
Your  Honeywell  ST9100C  provides  timing  control  for  your  central  heating  system, letting you set ON and OFF periods to suit your own lifestyle. 
The ST9100C 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.
With 7-day programming and up to 3 on/off periods per day, every day can be set differently.
The  following  instructions...



Your ST9100C should have been set up to work correctly when it was installed. However, the following will show you how you can modify your settings to meet your particular lifestyle.
To  assist  you  with  programming  and  everyday  use  your  ST9100C  will  display  text messages at every stage to help you get the most out of your central heating system. The  ST9100C  uses  LoT™  Technology  to  constantly  update  the  display  to  give  you feedback about what is required.

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).
