ChannelPlus H37XL
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 ChannelPlus H37XL is designed to give independent time
control over 3 channels of 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 H37XL as simple as possible to
use.
