Two Channel Central Heating and Hot Water Programmer

ChannelPlus H27XL

The ChannelPlus family of electronic programmers offer a range of advanced features coupled with simplified ‘menu driven’ programming and designed to help save energy.

The ChannelPlus H27XL is designed to give independent time control over heating and hot water on a 7 day weekly programme. Each channel offers up to 3 programmed On/Off operations per day for each day of the week.

For day to day operation each channel has a manual 1 or 2 hour boost button as well as an advance button to bring forward the next programmed operation. The back lit display, automatic clock and menu driven programming are all features designed to make the operation of the ChannelPlus H27XL as simple as possible to use.

Display Information

The Channel Plus H27XL programmer has a fully graphical, backlit display. In the normal run mode the display is divided into 2 sections, each section represents a controlled channel. The information displayed will change depending upon the settings made and which mode you are in.

During different programming modes and / or setting screens the current time, day/date, holiday indicator will only appear when necessary, this is to reduce confusion during the programming process. This is explained further in later sections of this guide.

Activating The Back-lit Display
The display will illuminate for approximately 1 minute whenever a button is pressed. To illuminate the display for viewing purposes only press the green set button under the front flap twice.

Setting and Adjusting
When setting or adjusting, the programmer will automatically return to the running mode if no buttons are pressed for approximately 1 minute. If the setting or adjusting has not been finished, please start the procedure again.

Time of Day
The ChannelPlus H27XL incorporates a factory set clock and calendar which means that no adjustments should be necessary to the time of day and BST / GMT time changes take place automatically. If adjustments are required please refer to page 11 of this booklet.

Manual Overrides
Boost function – 1 or 2 hour temporary override
The boost facility will allow the user to either activate a channel which is currently ‘OFF’ for 1 or 2 hours, or to extend a current ‘on ’ period by 1 or 2 hours. To indicate the boost being activated the ‘BOOST’ button under the selected channel will stay illuminated for the duration of the boost/extension period. The display will also indicate the extension to the time visually on the screen.

Advance function – brings forward the next on or off operation
The advance facility will allow the user to either bring a channel ‘ON’ which is currently ‘OFF’ or switch a channel ’OFF’ which is currently ‘ON’. To indicate the advance feature being activated the ‘ADVANCE’ button under the selected channel will stay illuminated until the next programme switching time, the user display will change to also indicate the status of the channel and the next switching time.

Programme Override Facilities
With the ChannelPlus H27XL programmer operating in the normal running mode it is possible to alter the functionality of the programme on each individual channel by means of the blue ‘select’ buttons under the front flap.

The options include:
AUTO – Programmer follows all programmed ‘ON’ and ‘OFF’ times.

ALL DAY – Channel operates from 1st ‘ON’ time until 3rd ’OFF’, ignoring all switching times in between.

ON – Channel will be constantly ‘ON’.

OFF – Channel will be constantly ‘OFF’, there is the ability to turn off heating during summer without altering the programme times. 1 or 2 hour boost still available.

All of the settings above will be permanent, i.e. unaffected by programme times, until alteration by the user.
The diagram below illustrates how to alter the setting, it assumes that the channel is in the AUTO mode to begin with. As all channels are totally independent it is possible to have them set differently if necessary*.

ADJUSTING SETTINGS
When carrying out any alterations to the programmed times and settings the programmer will return to its normal run mode in 1 minute if no adjustments are made in that time.

• It may not be possible to programme heating and hot water independently on certain systems.

Setting the Programme Times
The programme times have been preset as shown in the chart below.
Default Time Settings – AM/PM

Setting the Holiday Mode

The holiday mode can be used to suspend the program function of the ChannelPlus H27XL, it can be set in advance of your departure date and for as long a period as required. The holiday function operates from mid-day to mid- day, this means it can be easily set to ensure your home is warm for your return. When the holiday mode has been set a smiley face will appear on the display. When the holiday mode is active only the day/date and smiley face will be displayed. To cancel an active holiday period please press any of the select buttons under the front flap.
