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 opposite
