WHAT IS A PROGRAMMER?
General Description
Your  Honeywell  ST9500C  provides  timing  control  for  2  zones  within  your  central heating system, letting you set ON and OFF periods to suit your own lifestyle. 
The ST9500C 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. It is common to set the living area as zone 1, and the bedroom area as zone 2.
With 7-day programming...



Your ST9500C 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  ST9500C  will  display  text messages at every stage to help you get the most out of your central heating system. The  ST9500C  uses  LoT™  Technology  to  constantly  update  the  display  to  give  you feedback about what is required.

PROGRAMMING YOUR ST9500C
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).

PROGRAMMING YOUR ST9500C
Reviewing the Programme Times
To review your zone 1 programme, move the slider to the ZONE 1 position. 
To review your zone 2 programme, move the slider to the ZONE 2 position.
To  review  the  programme  times,  press  the   button  repeatedly.  The  appropriate ON  and OFF  markers  will  be  displayed  to  show  you  which  time  is  being  reviewed. Any  of  these  times  can  be  adjusted  by  using  the    or   buttons,  and  then confirmed  using  the   button....



Note:  When  pressing  the   button  the  next ON  or OFF  marker  may  start  to  flash. This indicates you have tried to set a time equal to one of the next programme times already  in  the  memory.    Similarly,  when  pressing  the   button  the  previous ON  or OFF  marker  may  start  to  flash.  This  indicates  you  have  tried  to  set  a  time  equal  to one  of  the  previous  programme  times.  If  this  happens  the  ST9500C  simply  moves both times together as long as you continue...
