User Operating Instructions

Three Channel Central Heating and Hot Water Programmer

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

The Horstmann ChannelPlus H37XL series 2 is designed to give independent time control over 3 channels of heating or 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 H37XL as simple as possible to use.

All series 2 ChannelPlus programmers are direct replacements for earlier ChannelPlus models.

Display Information

The ChannelPlus H37XL Series 2 programmer has a fully graphical, backlit display. In the normal run mode the display is divided into 3 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 menu button under the front flap twice.
