ThermoPlus AS2

User Operating Instructions

Programmable Room Thermostat

The Horstmann ThermoPlus AS2 is a battery powered

Programmable Room Thermostat that has been designed to make its operation very simple for the householder. The built in automatic clock means it will not need setting or adjusting for

BST and GMT time changes.

The ThermoPlus will provide a pre-programmed temperature profile preset by your installer and day-to-day user adjustments are carried out using just three buttons.

Being battery powered, the ThermoPlus AS2 is particularly suitable for use as a replacement for older style room thermostats, without the need to disturb existing wiring.

Part 1 - Day to Day operation

The ThermoPlus AS2 has been designed to be a simple to use thermostat, requiring minimal user intervention with a preprogrammed 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. 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 5.

Power Down Mode

During normal operation the AS2 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 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.

4

Warm and Cool Temperature Adjustment

The Warm and Cool target temperature settings on the

ThermoPlus AS2 are fully adjustable. To change a target temperature it is first necessary to press the centre button to bring up the 'Warm' or 'Cool' setting (indicated by the red or blue

LED indicators).

By using the up / down keys under the flap the Warm / Cool temperature can be increased or decreased to the desired temperature setting. See page 6.

PLEASE NOTE – it is not possible to set the warm setting to below that of the cool setting or vice versa.

Once a new temperature has been set in either the Warm or

Cool setting the AS2 will continue to use this setting until the next manual adjustment.

Battery Replacement

The ThermoPlus AS2 uses 3 x AA (LR6) batteries. The batteries supplied with the unit should last for approximately two years.

When the batteries are nearing the end of their life a 'LOW BAT' message will flash on the display.

To change the batteries it is necessary to remove the AS2 from the wall, to achieve this first press the RELEASE BUTTONS located under the unit and pull the AS2 away from the mounting plate by gently pulling up.

Before removing the old batteries please wait for at least 15 seconds after the last button was pressed. Remove old batteries and ensure the LCD display has gone blank before fitting the new batteries.

Replace with three new AA size alkaline batteries, ensure they are fitted correctly as shown by the marking positioned between the battery terminals. Once batteries have been fitted, replace the AS2 to the mounting plate, ensuring that the two guide lugs are fitted into the corresponding slots in the top of the mounting plate. Now push the AS2 until the release button clicks into place.

WARNING: You must ensure that the AS2 is always running on

3 x AA batteries and when the battery low message is displayed it is important that they are changed as soon as possible. This is to preserve the secondary internal reserve battery which is non- replaceable.

For best results use alkaline batteries rather than zinc carbon batteries.
