Maintenance

Must be maintained by a qualified

 

electrician or heating engineer

 

 

Lifestyle Programmers and Timeswitches conform to the essential requirements of these Directives:

89/336/EEC – Electromagnetic compatibility 73/23/EEC – Low voltage

BEFORE INSTALLATION

First, make sure the mains supply is switched off!

PROGRAMMER ONLY

The programmer must be set to the type of system it is to control. The link on the back of the unit has two settings – P and G.

P = a fully pumped and controlled system – allowing heating and hot water to be set separately.

G = a gravity-fed hot water system – which does not allow independent setting of heating without hot water, though hot water can be controlled alone.

USING AN EXISTING WALL-PLATE

Loosen the securing screws on the old programmer and unplug it. Check that there’s 70mm clearance to the right of the wall-plate, and 25mm above it. Check the chart on the next page to compare terminals and if necessary, change the wiring of the wall-plate to suit. Now plug the Lifestyle unit into the wall-plate and tighten the securing screws.

Check the 3A fuse, and switch on the mains.

FITTING A NEW WALL-PLATE

The ideal location is 1.4m above floor level, with reasonable lighting, good access, no condensation, no extremes of temperature, and a supporting surface that fully covers the back of the unit.

Position with 70mm clearance to the right, 25mm above, and sufficient room to access the securing screws underneath.

Fix, with terminals at the top, either direct to a flat wall using wall plugs and No. 6 x 1” (25mm) woodscrews, or on a flush mounting single conduit box type UA1 (BS4662) using M3.5 x 14 bolts. DO NOT USE A SURFACE MOUNTING BOX.

User’s Instructions

TIMESWITCHES

INTRODUCTION

Lifestyle Timeswitches will automatically control your system by switching it on and off at times that suit you. The red light on the front of the timeswitch shows when it’s on.

LP111 – a 24hr program, up to 3 heating periods each day, and every day the same.

LP711 – a 7-day program, allowing for different

timings on each day of the week, up to 3 heating periods each day.

If the engineer hasn’t set your timings for you, your timeswitch will work with a standard program that has been set at the factory. If this doesn’t suit you, it’s very easy to change it – when you’ve read this introductory section, simply turn to

the page for your timeswitch model.

Remember:

Make your changes using the SET?, YES/-, and + buttons.

You can’t set ON1 as the last timing before midnight, but you can set OFF3 after midnight – providing it’s not more than 23 hours and 59 minutes after ON1.

You need to set the timings in sequence – i.e. ON1, OFF1, ON2, OFF2, ON3, OFF3. If you get out of sequence, the display will flash a warning.

SWITCHING

ON 1 – start of first timed period

OFF 1 – end of first timed period

ON 2 – start of second timed period

OFF 2 – end of second timed period

ON 3 – start of third timed period

OFF 3 – final switch-off of the day

If the engineer has set your program and timings – you won’t need to do anything else. Just keep this guide in a safe place for future reference.

DAY-TO-DAY VARIATIONS

Sometimes you might need to change the way you use your system temporarily – perhaps due to an exceptionally cold day.

Here’s how to do it – without affecting the timings in your program.

Switching on and off

On the front of the timeswitch is an Advance button. It allows you to switch your system on or off, irrespective of the program. Press Advance to switch it on, and it will stay on until the end of the next OFF period. Turn it off, and it will stay off until the beginning of the next ON period.

DAY-TO-DAY VARIATIONS Cont...

Over-riding the program

At the side of the display there are four operating modes:

OFF

=

continuously off.

TIMED

= on for up to 3 periods a day.

ONCE

= on for 1 period a day, from the start of ON1

 

 

to the end of OFF3.

ON

=

continuously on.

Use the SELECT button under the flap to change the mode. This won’t alter the timings in your program, which you can return to by selecting TIMED.

THE LP111 24hr ELECTRONIC TIMESWITCH

LP111 – a 24hr program, up to 3 heating periods each day, and every day the same.

Want to leave a timing as it is? Just press SET? and move on to the next one.

If you need to reset your timings to the standard program and start again, press ‘SET’ and ‘+’ together to go back to the pre-set program.

The standard program

Your system will come on for up to 3 heating periods every 24hrs. ON1 starts the first one, OFF1 finishes it, and so on. Notice that ON2 and OFF2 are set to the same time.* This means your system won’t respond, but if you want to activate that middle period or change any other timings – read on.

Press the YES button, and you’ll see ON1, the start of your first heating period. Adjust it in 1-minute steps using the – and + buttons. If the – and + buttons are held down, the time changes in 10-minute steps.

Press SET?, and you’ll see OFF1, the end of your first heating period. Adjust this in the same way, press SET?, then repeat the procedure for ON2, OFF2, ON3 and OFF3.

When you press SET? after setting OFF3, the timeswitch will return to normal operation.

THE LP711 7-DAY ELECTRONIC TIMESWITCH

LP711 – a 7-day program, allowing for different

timings on each day of the week, up to 3 heating periods each day.

Want to leave a timing as it is? Just press SET? and move on to the next one.

If you need to reset your timings to the standard program and start again, press ‘SET’ and ‘+’ together to go back to the pre-set program.

Changing the timings

Press the SET? button and you’ll see ‘SET PROG?’.

PROG?

Set all weekdays

First you set the times that are going to be the same for each weekday, then you can select each day individually and make any further adjustments. If you want each day to be quite different, go straight to ‘Set each day’.

Press the YES button, and the display will ask ‘SET MON to FRI PROG?’.

PROGRAMMERS

If the engineer has set your program and timings – you won’t need to do anything else. Just keep this guide in a safe place for future reference.

INTRODUCTION

Lifestyle Programmers will automatically switch your central heating and hot water on and off at times that suit you. Depending on your system, central heating and hot water can either both come on and off at the same time, or work independently. The red light on the front of the programmer shows when each one is on.

There are 4 models in the Lifestyle range:

LP112 – a 24hr program, with linked central heating and hot water on for up to 3 heating periods each day, and every day the same.

LP241 – a 24hr program, with central heating and

hot water working independently for up to 3 heating periods each day, and every day the same.

LP522 – a 5/2-day program allowing for different

timings at the weekends, with central heating and hot water working independently for up to 3 heating periods each day.

LP722 – a 7-day program allowing for different

timings on each day of the week, with central heating and hot water working independently for up to 3 heating periods each day.

INTRODUCTION Cont...

If the engineer hasn’t set your timings for you, your programmer will work with a standard program that has been set at the factory. If this doesn’t suit you, it’s very easy to change it – when you’ve read this introductory section, simply go to the section that contains your programmer model.

Remember:

Make your changes using the SET?, YES/-, and + buttons on the programmer.

You can’t set ON1 as the last timing before midnight, but you can set OFF3 after midnight – providing it’s not more than 23 hours and 59 minutes after ON1.

You need to set the timings in sequence – i.e. ON1, OFF1, ON2, OFF2, ON3, OFF3. If you get out of sequence, the display will flash a warning.

SWITCHING

ON 1 – start of first timed period

OFF 1 – end of first timed period

ON 2 – start of second timed period

OFF 2 – end of second timed period

ON 3 – start of third timed period

OFF 3 – final switch-off of the day

The engineer has set your program and timings – you won’t need to do anything else. Just keep this guide in a safe place for future reference.

DAY-TO-DAY VARIATIONS

Sometimes you might need to change the way you use your central heating or hot water temporarily – perhaps due to an unusually cold day, or exceptional demand for hot water.

Here’s how to do it – without affecting your program.

Switching on and off

On the front of the programmer there are two Advance buttons

– one for central heating and one for hot water. They allow you to switch either on or off, irrespective of the program. So if the heating is off, and you want warmth now – press Advance to switch it on, and it will stay on until the end of the next OFF period. Or if the hot water is on and you don’t need it, press Advance and it will go off until the beginning of the next ON period.

Over-riding the program

On each side of the display there are four operating modes – one group for central heating, the other for hot water. You can change modes with immediate effect by using the appropriate SELECT button. This won’t alter the timings in your program, which you can return to by selecting TIMED.

OFF

=

continuously off.

TIMED

= on for up to 3 periods a day.

ONCE

= on for 1 period a day, from the start of ON1

 

 

to the end of OFF3.

ON

=

continuously on.

THE LP112 24hr ELECTRONIC PROGRAMMER

LP112 – a 24hr program, with linked central heating and hot water on for up to 3 heating periods each day, and every day the same.

If the timings haven’t been set for you, then your programmer will still be on the factory-set standard 24hr program, with central heating and hot water operating together on the same settings for every day of the week. But it’s easy to make changes – just follow the instructions.

Want to leave a timing as it is? Press SET? and move on to the next one.

If you need to reset your timings to the standard program and start again, press ‘SET’ and ‘+’ together to go back to the pre-set program.

THE LP241 24hr ELECTRONIC PROGRAMMER

LP241 – a 24hr program, with central heating and hot water working independently for up to 3 heating periods each day, and every day the same.

If the timings haven’t been set for you, then your programmer will still be on the factory-set standard 24hr program, with central heating and hot water operating together on the same timings for every day of the week. But it’s easy to make changes, and have heating and water working independently

– just follow the instructions.

Want to leave a timing as it is? Press SET? and move on to the next one.

If you need to reset your timings to the standard program and start again, press ‘SET’ and ‘+’ together to go back to the pre-set program.
