4.4 Closing the Switch Box (Fig.
- Replace the lower switch box cover (s)
(two screws).
"Thermen" Boilers:
- Reinstall the outer shell of the heater.
Central Boiler:
- Screw on the switch panel casing of
the boiler (four screws).
Note: The TA 210 E regulator can be
operated only when pump swit-
ching type III is selected on the
heating unit. For other pump swit-
ching types, "d2" appears in the
display of the heating unit.
5 Mounting of the Outdoor
Temperature Sensor AF
(Figures
4
The outdoor temperature sensor AF is sup-
plied with the regulator. It is intended for mo-
unting on the surface of an outer wall.
Important for the regulation quality of the TA
regulator is the selection of a suitable moun-
ting location for the outdoor sensor:
• Between the Northeast and Northwest si-
des of the house
• A minimum of 2 m over ground level
• It should not be influenced by windows,
doors, chimneys, direct sunlight or similar
effects (Fig. ).
4
• In recesses or under balcony and roof
overhangs are not suitable as mounting
locations (Fig. 4 ).
• If the major occupied rooms of the buil-
ding are all located in the same direction,
the outdoor sensor can point in that direc-
tion.
Note: If the outdoor sensor is mounted
on an east wall, the sensor must
be shadowed in the early morning
hours (e. g., by a neighbouring
house of a balcony).
Reason: The morning sun di-
sturbs the heating up of the house
after the end of the reduced night
program.

• If the major occupied rooms point in two
adjacent directions, mount the outdoor
sensor on the side of the house that has
the worst climatic conditions.
• For the mounting height, the (vertical)
middle of the height heated by the heating
unit has proven to the most suitable

For each of the time and remote controls
available as accessories, mounting instruc-
tions are provided. Mount the component to

7 Electrical Connection of the
Outdoor Sensor and Remo-
te Control (Figures
The electrical connection of the regulator
has already been described in Chapter 4.3.
Taking the applicable regulations into conside-
ration, the electrical cable used for the connec-
tion of the outdoor sensor and the remote con-
trol must be at least of the type NYM.
The following conductor cross sections
must be used:
• From the regulator to the outdoor sensor:
Length to 20 m
Length to 30 m
Length over 30 m
• From the regulator to the
remote control
All 24 V lines (measurement current) must
be laid separately from lines carrying 230 V
or 400 V so that no inductive effects take
place (Minimum distance - 100 mm).
