Technical data for the accessory item
6 720 612 220 GB (05.0 )
1 Technical data for the accessory item
• The TD 200 serves to display boiler and sys-
tem information and for hanging the dis-
played values. If the Servi e button is pressed
on the boiler, the TD 200 serves purely as a
display for the Servi e mode.
• The TD 200 is a timer with time programs for:
– Heating : 7 day heating program with
6 swit hing times per day
– Hot water : 7 day hot water program
with 6 swit hing times per day
• Room temperature ontrol of an unmixed
heating ir uit is possible in onjun tion with
the RT 10. The TD 200 re eives the current
room temperature via the temperature sen-
sor integrated in the RT 10.
• If no RT 10 is onne ted, the TD 200 works
purely as a timer with On/Off fun tion for the
time program without onsideration of the
room temperature.
• The TD 200 has a battery power reserve of
approx. 20 months. If the TD 200 has not
re eived any power for longer than 20
months, the time and date are deleted. All
other settings are maintained.
• Installation options:
– In the heating applian e with bus-enabled
Heatroni 3
– With optional a essory:
Wall mounting with bus onne tion to the
heating applian e with bus-enabled

Permissible able lengths of the bus-enabled
Heatroni 3 to the TD 200:
B To avoid indu tive influen es, lay all ables
arrying low voltage lines of 230 V or 400 V
separately (minimum spa ing 100 mm).
B Shield the ables in the ase of external
indu tive influen es.
This ensures that the ables are shielded
against external influen es (e.g. heavy urrent
ables, overhead onta t wires, transformer
stations, radio and television applian es, ama-
teur radio stations, mi rowave applian es
et ).
