Part 1 - Day To Day Operation; Power Down Mode - Horstmann ThermoPlus AS2-RF User Operating Instructions Manual

Part 1 – Day to Day operation
The ThermoPlus AS2-RF has been designed to be a simple to use thermostat, requiring
minimal user intervention with a pre-programmed heating profile. Simple temperature
adjustments can be easily carried out by using the '+' and '-' buttons. The indicator lights
react to any temporary user adjustments, with the LED indicators working in the following
way;
'Warm' is shown by two red lights and 'Cool' is shown by a single blue light (see Power
Down Mode below). The centre button marked 'Warm/Cool' allows you to toggle between
the warm and cool settings.
When one or more red lights are on, you can increase the temperature by pressing the '+'
button. For example, press once to go up by 1°C or press twice to go up by 2°C.
When the two or three red lights are on, the temperature can also be lowered by using
the '-' button. For example, press once to go down to the warm setting temperature and
press again to go down to 1°C below warm setting temperature. (Maximum adjustment
to warm temperature +/- 2°C). The blue light indicates the unit is working to the lower
set temperature. Please note that the '+' or '-' buttons will have no effect on the lower
temperature setting.
Under the flap is a blue button (6). 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 permanently adjusted, this operation
is detailed on page 4.

Power Down Mode

During normal operation the AS2-RF will go into Power Down Mode, this is to maximise
the life of the 3 x AA batteries fitted. Normal operation will continue during this mode, and
the heating will be unaffected. The result of the Power Down Mode will mean that the LED
indicators will not be displayed and LCD will not be illuminated, although the 'Warm' or
'Cool' temperature will be displayed.
To 'wake up' the AS2-RF press the 'Warm/Cool' button for 5 seconds, this will then
illuminate both the LED and LCD displays for a period. Any adjustment can then be made,
the Power Down Mode will commence again approximately 8 seconds after the last button
press.
