General
1 General
The functions and parameters are changed in the TROVIS-VIEW software. To transfer settings
from the software to the electric actuator or vice versa, they must be connected. See
uEB6661.
The software in online mode has a direct inuence on the connected device, and, as a result,
on the valve. To avoid personal injury or property damage, plant operators and operating
personnel must prevent hazards that could be caused in the control valve by the process me-
dium, the operating pressure, the signal pressure or by moving parts by taking appropriate
precautions. They must observe all hazard statements, warning and caution notes in the ref-
erenced documents.
Accessories for communication:
The TROVIS-VIEW software for revision 2 of the
TROVIS5757-3
Electric Actuator with Pro-
cess Controller is required. The TROVIS-VIEW software can be downloaded free of charge
from our website (uwww.samson.de at Services > Software > TROVIS-VIEW). The software
can also be supplied on a CD-ROM. Further details can be found in Data Sheet uT6661.

Fig.1: DHW heating in instantaneous heating system with ow sensor and DHW tapping
recognition
The DHW temperature is controlled to the set point temperature in DHW heating in instanta-
neous heating systems:
ÎIf the DHW temperature falls below the set point, the actuator opens the valve (pulses) to
increase the DHW temperature.
ÎIf the DHW temperature exceeds the set point, the actuator closes the valve (pulses) to
reduce the DHW temperature.

Functions and parameters
Operation with a DHW sensor
A Pt1000 temperature sensor (e.g. Type5207-0060, ideally combined with a sensor pocket
to provide the best positioning of the sensor at the heat exchanger) measures the DHW tem-
perature at the heat exchanger. The measured temperature is compared with the set point
and the valve is moved accordingly to achieve this temperature (see above).
Operation with a current input
As an alternative to a ow sensor, the input of the current ow temperature can be also be
implemented by the current input (0 to 20mA or 4 to 20mA). The input signal is based on
the measuring range (Xmin to Xmax). The measured DHW temperature is compared with the
set point and the valve is moved accordingly to achieve this temperature (see above).
The function to maintain the water temperature at a constant temperature (see section2.3)
cannot be used when the current input is active.
Functions WE Conguration
F05: Current input 0F05 - 1
F06: Function of current input 0F06 - 0
F07: Measuring range of current input 0F07 - 0: 0 to 20mA
F07 - 1: 4 to 20mA
Parameters WE Value range
P03: Lower measuring range value Xmin 0°C –50 to 90°C
P04: Upper measuring range value Xmax 100°C 10 to 150°C
2.1.1 DHW tapping recognition with a ow switch
The ow switch is used to indicate when DHW tapping is starts and nishes. A closed contact
causes the pump to start running (the DHW temperature control at the DHW sensor is active).
An open contact causes the valve to close and the pump to be switched off.
Functions WE Conguration
F01: DHW tapping recognition 1 F01 - 1
F02: Flow rate sensor 1 F02 - 0

Functions and parameters
2.1.2 Tapping detection using the water ow sensor
In contrast to the DHW tapping recognition with a ow switch, the extent of tapping is indi-
cated as well as when the DHW tapping starts and nishes.
By activating the optimizing function Adaptation, the device adapts itself to changing net-
work conditions without having to change the control parameters (see section2.6). The opti-
mizing function can only be activated when a water ow sensor is used.
Hot water being tapped is also detected when the maximum ow rate of the water ow sen-
sor is exceeded.
Functions WE Conguration
F05: Current input 1 F01 - 1
F06: Function of current input 1 F02 - 1
F07: Measuring range of current input 1 F07 - 1
2.2 Set point changeover
The device can use two different set points, W1 and W2, for control, e.g. hot water tempera-
ture in normal used and for thermal disinfection. The set points changeover is implemented
by the binary input (BI1):
−BI1 open: W1 is the set point
−BI1 closed: W2 is the set point
It is only possible to change between set points W1 and W2 when the DHW temperature is
measured with a Pt1000 resistance sensor (F05 - 0).
When the binary input BI1 is used, the current input cannot be used. It also not possible to
deactivate the function to maintain the heat exchanger at a constant temperature (see sec-
tion2.3) when the binary input is used for set point switchover.
Functions WE Conguration
F05: Current input 0F05 - 0
F08: Function of binary input 0F08 - 1

Functions and parameters
2.3 Maintaining the heat exchanger at a constant temperature
When the DHW tapping recognition is active, the actuator controls the hot water to the set
point temperature only when hot water is demanded. To guarantee that the temperature
reaches the set point W1 quickly when hot water is demanded again, the heat exchanger is
prevented from cooling down by the function to maintain the heat exchanger at a constant
temperature: the hot water is kept at a temperature reduced by the set-back difference.
Depending on the conguration, the reduced set point applies after hot water has been
tapped until the next demand or while the heating period to maintain heat exchanger at con-
stant temperature (P12) is active.
Upon power supply failure, an active function is canceled. After the power supply is recon-
nected, hot water must be tapped to reactivate the function.
Functions WE Conguration
F01: DHW tapping recognition 1 F01 - 1
F09: Maintain heat exchanger at constant
temperature
0F09 - 0: Time adjustable (P12)
F09 - 1: Continuous
Parameters WE Value range
P11: Set-back difference 8K 0 to 30K
P12: Heating period to maintain heat ex-
changer at constant temperature
24.0h 0 to 25.5h
Inuence of the binary input BI1
If the binary input BI1 is not required for set point switchover, it is used to deactivate the func-
tion to maintain the heat exchanger at a constant temperature.
−BI1 open: function to maintain heat exchanger at a constant temperature according to
conguration of F09.
−BI1 closed: function inactive
When the binary input BI1 is closed, an active function to maintain the heat exchanger at
a constant temperature is immediately terminated, even when the Heating period to
maintain heat exchanger at constant temperature has not yet elapsed.

F05: Current input 0F05 - 0

2.4 Excessive temperature protection
The actuator closes the valve when the ow temperature at the ow sensor exceeds the upper
limit (GWH).
When F10-0 is congured, no monitoring of the ow temperature for violation of the upper
limit takes place.
Functions WE Conguration
F10: Upper limit (GWH) 0F10 - 1
Parameters WE Value range
P05: Upper limit (GWH) 95°C 0 to 100°C
2.5 Frost protection
When the function is active, the ow temperature is monitored for violation of the lower limit.
When the temperature falls below the lower limit (GWL), the actuator opens the valve (puls-
es) until the temperature exceeds the lower limit plus hysteresis.
When F11-0 is congured, no monitoring of the ow temperature for violation of the lower
limit takes place.
Functions WE Conguration
F11: Lower limit (GWL) 0F11 - 1
Parameters WE Value range
P06: Lower limit (GWL) 5°C 0 to 20°C

Parameters WE Value range
P07: Proportional-action coefcient KP 0.8 0.1 to 50
P08: Reset time Tn 15s 0 to 999 s
P09: Derivative-action time Tv 0s 0 to 999 s
P10: Actuator transit time Ty 25s 0 to 240 s
The actuator transit time Ty actuator transit time for valve travel (P10) reects the time that the
valve needs to move through the range from 0 to 100% without stopping. The default setting
is 25s.
The default setting is based on the rated travel of 6mm. The actual transit time can be deter-
mined by the "Start transit time measurement" parameter. See section4.4.
2.7 External demand processing
The device can process an external demand for heat depending on the conguration. A
measuring range (Xmin to Xmax) is assigned to the current signal (0 to 20mA or 4 to
20mA, set point). The external hot water set point has priority over the internal set point.
Only a Pt1000 sensor can be used to measure the hot water temperature when the function
for an external demand is active.

F05: Current input 0F05 - 1
F06: Function of current input 0F06 - 1
