5.Control system - Meibes

7. System examples
7.1 Freshwater station with
circulation in a time-slot
and with tapping detection
outside the time slot
■ Initial operation and system calibration from point 6
■ Setting the time and date, point 5.3.3
■ Domestic hot ■ set value e.g.: 50°C, point
water 5.3.3 and 5.3.5
■ Circulation ■ Basic setting menu,
Circulation submenu = select
“on”, point 5.3.5
■ In programming menu,
circulation submenu up
to 3 select time slot,
point 5.3.3
■ Circulation temperature 40°C,
for control in time slot,
point 5.3.5
■ Circulation time e.g.: 60 s,
Circulation rest time.: e.g.
10 min, for controlling the
circulation through tapping
detection outside the
time slot, point 5.3.5
■ Heat transfer unit ■ WT = cold, point 5.3.3
■ Time lag ■ e.g.: 20 s, point 5.3.5
7.2 Freshwater station with
circulation only via tapping
detection
■ Initial operation and system calibration from point 6
■ Setting the time and date, point 5.3.3
■ Domestic hot ■ set value e.g.: 50°C,
water point 5.3.3 and 5.3.5
■ Circulation ■ Basic setting menu,
Circulation submenu = select
“on”, point 5.3.5
■ In programming menu,
Circulation submenu is the
start and stop times within
each 3 time slots which are
to be set at the same time
e.g.: start 6h00 - stop 6h00
point 5.3.3
■ Circulation time e.g.: 60 s,
Circulation rest time e.g.:
10 min, point 5.3.5
■ Heat transfer unit ■ WT = cold, point 5.3.3
■ Time lag ■ e.g.: 20 s, point 5.3.5

7.3 Freshwater station without
circulation
■ Initial operation and system calibration from point 6
■ Setting the time and date, point 5.3.3
■ Domestic hot ■ set value e.g.: 50°C, point
water 5.3.3 and 5.3.5
■ Circulation ■ Basic setting menu,
Circulation submenu = select
“off”, point 5.3.5
■ Heat transfer unit ■ WT = cold can be selected,
if the distance between
the buffer and the freshwater
station is not too great.
After-run e.g.: 20 s,
point 5.3.5
■ WT = hot can be selected,
if there is a great distance
between the buffer and the
freshwater station, and the
comfort of the “rapid” hot
water drawing has been
attained. Set the after-run
point 5.3.5 on nought, as no
circulation pipe is available.
