The time program consists of 4 timer cycles. Cycle 1 is preset at the factory from
06:00 to 22:00 hrs, i.e. the DHW recirculation pump is on during this period.
The automatic mode is also selected, i.e. the DHW recirculation pump runs parallel
to the domestic hot water heating time program.
You have the following options to set the timer cycles to suit your requirements:
By setting the corresponding timer cycles, the DHW recirculation pump can be
switched on and off up to 4 times per day.
You can set identical timer cycles for every day of the week or individual timer
cycles for each day of the week.
The DHW recirculation pump should run at those times when you require hot water.
Please see the note headed "Important" on page 16.
When timer is programmed with --:--, DHW recirculation pump is off.
When timer is programmed with ON 00:00, OFF 24:00, DHW recirculation pump
operates continuously.
