ENGLISH
If no storage cylinder sensor is connected, storage temperature is set at 25 °C.
6.5.3.1 Storage stratification
Activates or deactivates stratification.
6.5.3.2. ΔT storage return = The temperature differential for upper storage stratification
If the temperature of the primary circuit exceeds the difference set here, the valve is activated to buffer the top of the
storage cylinder.
If primary circuit temperature drops below this value, the valve is closed again. If no storage sensor is connected, storage
temperature is set at 25°C.
6.5.4. V1 parallel functioning
This function activates the selected relay with a 0-10V / PMW V1 output in parallel to V1.
b
High efficiency pumps with a 0-10V / PWM signal can be powered using the additional function “Always on” or
“Parallel functioning V1/V2” via relays 1-3.
6.5.4.1. V1 parallel functioning
Activates, deactivates or inverts parallel functioning.
6.5.4.2. Delay
The assigned relay is activated after V1 by the delay set here.
6.5.4.3. Off delay
The assigned relay remains active after V1 by the delay set here.
6.5.5. V2 parallel functioning
This function activates the selected relay with a 0-10V/PMW V2 output in parallel to V2.
6.5.6. Always on
The selected relay is permanently on.
b
High efficiency pumps with a 0-10V / PWM signal can be powered using the additional function “Always on” or
“Parallel functioning V1/V2” via relays 1-3.
6.6. Relay 2
See the functions for Relay 1.
6.7. Relay 3
See the functions for Relay 1.
6.8. V2 signal
This function allows the PMW / 0-10V V2 output to control an additional high efficiency pump. If a pump function is ac-
tivated (e.g. recirculation, solar, additional pump, etc.) the additional settings and speed control for pump V2 must also
be set.
See the technical specifications for the PMW / 0-10V outputs.
6.8.1. V2 signal
See the functions for Relay 1.
6.9. Pressure control
The relay is active when pressure drops below the minimum setpoint or exceeds the maximum setpoint.
Settings range: On, Off / Default: see table.
6.9.1. Pressure control
This menu is used to activate monitoring of system pressure via a direct sensor. The relay becomes active as soon as the
values set here are exceeded.
6.9.2. RPS1 / RPS2 = Type of pressure sensor
This menu sets the type of pressure sensor used.
N.B.: if a VFS1 type sensor is connected, for example, the RPS1 option is not displayed.
Settings range: Off; 0-0.6 bar; 0-1 bar; 0-1.6 bar; 0-2.5 bar; 0-4 bar; 0-6 bar; 0-10 bar / Default: see table.
6.9.3. Pmin
Minimum pressure. If pressure drops below this value, an error message is displayed and the relay is activated.
Settings range: Off; 0.0 to 1.6 bar
6.9.4. Pmax
Maximum pressure. If pressure exceeds this value, an error message is displayed and the relay is activated.
Settings range: Off; 0.0 to 10 bar
6.10. Sensor calibration
Deviations from set temperatures, for example as a result of over-long cables or badly positioned sensors, can be com-
pensated manually by way of this menu. Adjustments can be made for all sensors in steps of 0.5 °C.
b
Settings are necessary only in exceptional cases, when the system is first started up, and must be made by an
expert service technician. Wrong values can cause the system to malfunction.
6.11. Start-up
The setup wizard guides the user through the settings needed to render the system operational, indicating the correct
