Operating the System Controller
Volume flow encoder VSG 2,5
Room sensor RS-SC
4.3 Accessories
• Temperature sensor SolvisControl TF-SC
as flow sensor for heat circuit 1 (S12), heat circuit 2
(S13) , as circulation sensor (S11) or as hot water
return sensor lets you control the hot water circulation
with SolvisControl. With 3 m connection cable, including
heat-conducting paste, cable ties and insulation bush.
If S11 is connected, you may have to set the times for
circulation. . . . . . . . . . . . . . . . . . . . . . . . . . .

• Volume flow encoder VSG-2,5 (figure on right)
for connection to SolvisControl, input S15. This allows
you to measure and display the current heat output
and the accepted heat quantity in the secondary solar
circuit.
Suitable for up to 1.5 m³/h. Including screw connections
for 18 and 10 CU pipe (solar line).
The impulse rate of the volume flow encoder is
0.5 l/Imp. and is installed on the relevant input (S15)
of the SolvisControl at the factory.
If you are using an on-site volume flow encoder, you will
have to set the impulse rate at input S15. . . .

• Room sensor RS-SC (figure on right)
lets you set the room temperature and heating program
in a room that is far removed from the controller.
Set the controller after installation of the controller
(at input S16). . . . . . . . . . . . . . . . . . . . . . . . .

Limitation:
- You can connect only one room sensor.
- You may only operate this sensor at heat circuit 1.
- You are no longer able to heat a swimming pool.
You can also use the room sensor to control the
room temperature in the respective room based
on the flow temperature so that it takes into con-
sideration external heat sources such as a fire-
place or sun exposure. All radiator valves in that
room have to be open for that purpose. You will
also have to set the so-called “room influence
factor” on the SolvisControl. More information in
section “4.4 Using the room sensor”. .
