Note: Always switch the mains off first
GB and never fit/remove the timer to/from a live wallplate.
3.5With the unit powered up, it is recommended to press and release the RESET button to start up the FP735Si unit.
4.0 Programming Options
FP735Si is delivered with a set of parameters that have been preprogrammed to cover the most typical type of installations. See (5.0). If a different parameter setup is wanted the unit provides two programming options:
4.1Normal programming
Normal Programming is meant for setting the timing profile that controls the ON and OFF periods for the room heating and for the hot water. A daily profile may be programmed and a profile can control the entire week where the weekend may be handled separately. Also a timing profile for a holiday can be entered.
As part of the normal daily operations, a simple one-button press (+HRS) can extend a running ON period for room heating and/or hot water by one hour. This can be repeated 3 times giving up to 3 hours extension.
