3.3.4 Timer program and legionella prevention
When Lock is ON a password is needed to access the following menus.
When lock is OFF the following menus are directly accessable (The display
shows a * in the lower right corner).
1. Default program
These programs are selected based on the typical water usage at the tap of
the concerned building. For example: a large amount of hot water will be
tapped in the morning around 7.00 am. Due to the continuous flow of hot
water in the pipes, the heat loss will be minimum and the heater can be off
power in order to save energy. Similar behaviour can occur during night
time. The choice of the optimum timer program for the application ensures
that the hot water temperature maintenance system works even more effi-
ciently. Any timer program can be edited to suit personnel requirements
(See 2 Edit program).
The following pre-programs are available.

The time tables of all pre-programs are given in appendix 5.2 diagram I,
page 35. After selecting a pre-program the HWAT-ECO shows a row of
dots on the display. This is because it takes a few seconds to program the
internal memory.
2. Edit program (incl. legionella prevention)
Timer programming is done graphically in 1/2 hour time blocks.
A block can be set to Off, Economy temp, Maintain temp, or 100% power
(100% only if HWAT-R cable is used).
