ThermoPlus AS1
User Operating Instructions
The ThermoPlus AS1 - Programmable Room Thermostat offers
a number of pre-installed heating profiles which are simple to
set-up by the installer or user to provide maximum
comfort. Once complete, user operations are kept to a
minimum by using the +/ - and Warm/Cool buttons on the front
of the unit.
PLEASE NOTE: The ThermoPlus contains a selection of five
pre-set and one adjustable profile options, one of these profiles
should have been set by the Installer to meet your heating
requirements. Care should be taken to ensure the correct
profile is selected that most suits your lifestyle. Details on
how to change the selected profile are located on page 9 of
this guide.

Introduction and operating guide
The ThermoPlus AS1 has been designed to be a simple to use
thermostat, requiring minimal user intervention. The normal day
to day operation is taken care of by the pre-set heating profiles,
any temporary adjustments are simply made by using the + and
– buttons. The indicator lights react to any temporary user
adjustments made, the LED indicators work in the following
way;
Warm is shown by two red lights (6) and Cool is shown by a
single blue light (5). The centre button (3) marked 'Warm/Cool'
allows you to toggle between warm and cool settings.
When one or more red lights are on, you can increase the
temperature by pressing the + button (1). For example, press
once to go up by 1 degree or press twice to go up by 2 degrees.
When the two or three red lights are on, the temperature can
also be lowered by using the – button (2). For example, press
once to go down to the warm setting temperature and press
again to go down to one degree below warm setting
temperature.
The Blue light means the unit is working to the lower
temperature and the + or – buttons do not work when this blue
light is on. To change to the warm setting press the 'Warm/Cool'
button.
Under the flap (7) is a blue button (4). During the summer, or
when you want your central heating off for long periods, for
example if you go on holiday, press the Blue button and close
the flap. When you want to go back to normal operation, open
the flap and press the blue button again, remembering to close
the flap once finished.
Both the Warm and Cool temperature settings can be fully
adjusted, this operation is detailed on the next page.
