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.
