13 Room sensor RF OFF When FB 13 = ON, the room temperature
display does not affect the control loop; when
Type 5244 or Type 5257-4 Sensors with remote
control are connected, the remote adjustment of
operating modes is additionally activated
14 Storage tank
sensor SF1
(See chapter 5 for
description on switching
behavior)
ON 2, 3,
4.1,
4.2, 5
When FB 14 = ON, the sensor SF1 is activated.
Fb14 cannot be deactivated in Anl 2.1, 4.1 and
4.2. It can only be deactivated in all other
systems when FB 15 = OFF. Set FB 14 = FB 15 =
OFF when storage thermostat is used!
15 Storage tank
sensor SF2
(See chapter 5 for
description on switching
behavior)
ON 2, 3,
4.1,
4.2, 5
When FB 15 = ON, the sensor SF2 is activated.
Fb 15 cannot be deactivated in Anl 2.1, 4.1, 4.2
16 Sensor selection OFF When FB 16 = OFF, PTC and Pt100 sensors can
be connected, mixed circuit is possible.
When FB 16 = ON and "P1000" is selected,
Pt1000 and Pt 100 sensors can be connected,
when "ntc" is selected, NTC and Pt 100 sensors
can be connected, mixed circuit is possible
17 3-point stepping
control for
drinking water
circuit, control
parameters
ON Only
4, 5, 6
When FB 17 = ON, the drinking water circuit
functions as 3-point stepping control loop. Enter
the following:
K
P
= 0.1...50.0 (default: 2.0),
T
N
= 1...999 sec (default: Anl 5, 6: 60 sec;
Anl 4: 200 sec), Ty = 15, 30, 45, ..., 240 sec
(default: Anl5, 6: 30 sec; Anl4: 90 sec)
When FB 17 = OFF, the drinking water circuit
functions as on/off control loop.
Enter differential gap = 1 to 30
°
C (default:5

C)
18 Outdoor
temperature
 signal input
OFF When FB 18 = OFF, the sensor input for outdoor
temperature measurement is activated.
When FB 18 = ON, the signal input for outdoor
temperature measurement is activated.
Option between 0 or 4 to 20 mA signal
connection
(Measuring range: 20...+50 °C).
Connect a 50 Ohm resistance to terminals 3 (+)
and GND (terminals 5 to 8) parallel to signal!
19 Circulation
via heat exchanger
(See chapter 5 for
description)
OFF 5 When FB 19 = ON, the control release of the
drinking water circuit is retained even after
active storage tank charges
