The programmer is located behind the hinged cover on the facia panel, adjacent to the boiler
thermostat contol knob. On fully pumped systems the programmer will allow the hot water and
central heating to work independently of each other, if required. However, on systems with gravity
hot water and pumped central heating, the hot water shares the central heating programme. The
programmer can be set to allow for different times on week days and weekends, pre-set
programmes are protected in the event of a power failure by a rechargeable battery back-up. On a
fuHy
pumped system it is possible to have four 'On' settings (2 for centra] heating and 2 for hot
water) and four 'Off' settings per day. Programmes can be advanced using the 'On' facility to
override what would otherwise be an 'Off' period.
