TA 211 E
English
7.3.3 Night Reduction (d)
In the position (frost protection), the heat-
ing unit remains switched off as long as the
outside temperature is above +4 °C. Burner
and pump are not in operation (see
Section 7.2).
The night reduction determines by how many
K (°C). The heating curve is shifted parallel
downward in reduced operation (the broken
line in Fig.
). Values between 0 and – 40 K
(°C) can be set.
Select a setting with which the desired
temperature reduction is achieved.
Note: A reduction of the flow temperature by
5 K (°C) results in approx. 1 K (°C)
room temperature reduction.
7.4 TA 211 E with Time Switch and TW 2
Remote Control (Accessory) (not in UK)
The TW 2 Remote Control is effective only
when the operating mode switch (b) of the
TA 211 E is in the position . If this is the
case, the operating mode can be set with the
operating mode switch on the remote control.
Set the base point for normal operation and
night reduction as described in Section 7.3.
In the position of the operating mode
switch on the TW 2 , a fixed reduction value
of 25 K (°C) is pre-programmed. The reduc-
tion value set on the adjustment knob of
the TA 211 E is not effective in this case.
Should the reduction value of 25 K (°C)
be too high or too low for longer absences, the
operating mode switch (b) of the TA 211 E
can be temporarily set to the position and
any desired reduction value selected on the
knob (d).
A detailed functional description can be found
in the operating instructions of the TW 2.
7.5 TA 211 E with TFQ 2 or TFP 3
Remote Control (Accessory) (not in UK)
The remote control is effective only when the
operating mode switch (b) of the TA 211 E is
either in the position . The operating mode
can then be set exclusively by means of the
operating mode switch on the remote control.
Note: The degree of flow temperature re-
duction is also set exclusively on
the TFQ 2/TFP 3.
A detailed functional description is provided
with the remote control.
8 Programming the time switch
(Accessory)
The TA 211 E is delivered without a time
switch.
For the operation of the time switch, refer to
the associated operating instructions.
9 General Notes
Heating units that can be operated with the
TA 211 E Regulator are equipped with an au-
tomatic device that limits the switching fre-
quency in two-point operation of the burner.
For more detailed information, refer to the in-
stallation instructions of the heating unit.
A frost protection circuit is also built into the
switching box of the heating unit that keeps
the flow temperature above +10 °C.
10 Malfunction
A malfunction of the regulator or a faulty con-
nection are indicated with an error code on the
control panel. The following error codes are
caused by the regulator TA 211 E:
“AC” Contact failure or malfunction of the
regulator.
“CC” Contact failure or defect external tem-
perature sensor.
