...an Explanaon for Householders. Pro-
grammers allow you to set ‘On’ and ‘O’
me periods. Some models switch the
central heang and domesc hot water
on and o at the same me, while others
allow the domesc hot water and heang
to come on and go o at dierent mes.
Set the ‘On’ and ‘O’ me periods to suit
your own lifestyle. On some programmers
you must also set whether you want the
heang and hot water to run connuously,
run under the chosen ‘On’ and ‘O’ heang periods, or be permanently o. The me on
the programmer must be correct. Some types have to be adjusted in spring and autumn
at the changes between Greenwich Mean Time and Brish Summer Time. You may be
able to temporarily adjust the heang programme, for example, ‘Advance’, or ‘Boost’.
These are explained in the manufacturer’s instrucons. The heang will not work if the
room thermostat has switched the heang o. And, if you have a hot-water cylinder, the
water heang will not work if the cylinder thermostat detects that the hot water has
reached the correct temperature.
Please refer to the installing instrucons for any informaons about standards and pro-
duct environment.
