The slope is set to 0.8 at the factory. Depending on the
building/heating type, the correct heating curve must be
set to ensure that controller functions properly.
Set heating curve, if necessary . . . . . . . . . . .

If no outdoor sensor is connected, “OPERATION: MAL-
FUNCTION” is displayed in the heating circuit. The con-
troller reads an outdoor temperature of 0°C and deter-
mines the corresponding flow target temperature from
the heating curve. However, it can be set to any flow
temperature by changing the mode of the controller
from “OUTDOOR TEMPERATURE” to “FIXED VAL” in
the heating curve menu (
page 39
) and by setting the
required flow temperature in normal mode for “T.Pre.-
20°C” and the required flow temperature in lowering
mode for “T.Pre.+10°C”. See “Setting the heating
curve in Temp mode”. . . . . . . . . . . . . . . . . . .

Only for underfloor heating with mixer circuit:
Reduce the maximum flow temperature of the mixed
heating circuit in the heating circuit of the controller
function menu to the required value.
If the maximum flow temperature is 35°C, for example,
in the heating circuit controller menu to which the
underfloor heating is connected, you must reduce
“T.PRE.MAX” from 70°C (factory setting) to 35°C,
“Setting flow temperature limit” . . . . . . . . . . . .

Of course, thermostatic flow temperature limiters
must be installed where they are prescribed.
•
Adjust the switch-off conditions of the heating pump to
the requirements of the system operator.

d) Heating circuit “HEAT CIR.2” (optional):
If a second heating circuit is connected, carry out the
steps described under c).
e) Setting the flows of the solar circuits
For the control to function, there has to be a minimum
flow in the primary and secondary solar circuit set by the
minimum speed level.
Match the minimum speed level of both solar pumps to
the actual pressure loss at the solar circuits . . .

f) Swimming pool heating (optional):
After connecting the swimming pool sensor, first set the
controller, . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

then the heating times. Factory setting: Mo – Su: 0:00 –
0:00, which means deactivated, only solar heating is
possible; set required time, if necessary . . . . . .

g) Heat output in the solar circuit (optional):
Set impulse rate for heat quantity measurement at the
volume flow measuring unit, if necessary (accessories,

Please enter the start-up information in the start-up
report that is included.
•
Instruct the operator concerning the operation of the
SolvisControl.
•
Keep the entire installation and operating instructions
near the machine.
