Appendix: Information on SolvisControl system controller
The sensors on the inputs are described here. The posi-
tions of the sensors are shown in the system diagrams
in the
Appendix (p. 67f
). The following measured quanti-
ties
(“display name”/sensor designation)
are displayed:
1: Hot water buffer temperature (“T.WW.Buffer”/S1)
The sensor is in the upper third of the storage tank, and
it displays the temperature of the water in that location
(hot water buffer). It must be at least 10 K to 12 K
above the target hot water temperature to guarantee
that the water that comes out of the tap reaches the set
hot water temperature. If that is not the case, you must
check (
p. 43
) the “DIFF.ON” temperature increase. In the
second step, check whether the auxiliary heating pro-
vided by the boiler is working correctly.
2: Hot water temperature (“T.Warm Water”/S2)
The sensor is directly in the output of the hot water
heat exchanger. It displays the temperature of the
heated drinking water after it has passed through the
heat exchanger.
3: Storage tank reference temperature (“T.Ref.Sto”/S3)
The sensor is at the bottom of the tank. It displays the
temperature used to switch on the solar pump when
there is a difference between the collector and the
storage tank (S8 – S3).
4: Upper heating buffer (“Temp. upper heating buffer”/S4)
The sensor is located at the top of the buffer below the
hot water buffer sensor S1. It limits the upper layer of
the tank, which holds heating water required for room
heating. The temperature it displays should be at least
as high as the higher target flow (“pre-run”) temperature
in the heating circuits.
5: Solar flow (“T.Solar Pre2”/S5)
Temperature sensor in the flow of the secondary solar
circuit (plate heat exchanger storage tank) necessary for
recording solar yields.
6: Solar return (“T.Solar Ret2”/S6)
Temperature sensor in the return of the secondary solar
circuit (plate heat exchanger storage tank), required for
recording solar yields.
7: Solar flow (“T.Solar Pre1”/S7)
The sensor is located in the flow (from the collector)
of the primary solar circuit.
8: Collector temperature (“T.Collector”/S8)
It displays the temperature measured at the hottest
part of the collector (at the collector outlet).

9: Lower heating buffer (“T.H.Buffer U”/S9)
The sensor is located about in the middle of the tank.
It limits the lower layer of the tank, which holds heating
water required for room heating. If the hot water demand
is particularly high at certain time, this sensor can
increase the hot water buffer area.
10: Outdoor temperature (“Outside temp”/S10)
Shows the outdoor temperature. The sensor should be
mounted roughly 2 meters above the ground on one of
the building’s exterior walls that does not receive direct
sunlight (such as the north side).
11: Circulation temperature (“T.Cir.Ret”/S11)
The temperature measured in the circulation pipe (if
applicable). The sensor must be mounted on the return
of the circulation pipe, between the pipe and the insula-
tion. It should not be directly next to the pump.
12: Flow (“pre-run”) temp. Heating circuit
(“T.Heat.Cir.P1”/S12)
Temperature sensor on the flow of mixed heating circuit 1.
It uses the mixer to control the flow temperature.
13: Flow (“pre-run”) temp. Heating circuit
(“T.Heat.Cir.P2”/S13)
Temperature sensor on the flow of mixed heating circuit 2.
It uses the mixer to control the flow temperature.
14: Return temperature of the hot water heat exchanger
(“T.WW.Ret”/S14)
The sensor is located on the return of the primary
circuit of the hot water heat exchanger. It displays the
temperature of the storage tank water used for gener-
ating hot water when it returns to the tank.
15: Flow measurement (“Solar Flow.2”/S15)
Optional. display of the volume flow in the secondary
solar in l/h. The volume flow meter is located in the
return of the secondary solar circuit.
16: Room temperature (“T.Room1”/S16), alternatively:
Swimming pool temperature (“T. swimming
pool”/S16)
Connection of room sensor or temperature sensor for
swimming pool heating as immersion sensor in the
sequence of the filter circuit.
