An introduction to your 
programmable room thermostat
Your programmable room thermostat allows you to programme 
di erent temperatures at di erent time periods. You can programme 
one set of times and temperatures for week days with a di erent 
set of temperatures for weekend days, this is referred to as 5/2 day 
operation.
The thermostat can also be set up by your installer to provide one set 
of times and temperatures that are repeated each day of the week. This 
is referred to as 24 hour operation.
The thermostat can also be set by you to provide two di erent 
programming blocks which can then be assigned to any day of the 
week, this is referred to as A/B programme operation.
All thermostats can be set by your installer to provide up 2, 4 or 6 time 
and temperature settings each day.
All thermostats feature useful overrides, including a programmable 
frost setting.
Your thermostat has some advanced features which the installer will 
set-up if they are required. There are also a number of advanced features 
which can be set up by you. These advanced settings alter the way that 
your thermostat operates, some also a ect the programming functions 
and the user overrides. Please read the User Advanced Programming 
instructions before programming the unit (see page 25).
