The thermostat function works independently
from the solar operation and can e.g. be used for
use of surplus energy or an after-heating.
• AH O < AH F
the thermostat function is used for after-
heating
• AH O > AH F
the thermostat function is used for use of
surplus energy
is shown on the display if the second relay
output is activated.
A relative minimum pump speed is specifi ed for
pumps connected at the outputs R1 and R2 via
adjustment channels nMN, n1MN and n2MN.
Attention:
When using consumers (e.g. valves) which
are not pump speed controlled, the value
must be adjusted to 100 % in order to
deactivate the pump speed control.
For control- and service work the operating mode
of the controller can be manually adjusted by
selecting the adjustment value Manual Mode, for
which the following adjustments can be made:
• HND1 / HND2
Operating mode
OFF : relay off,
display:
AUTO : relay in automatic operation
ON : relay on,

When the parameter is set to 1, the correspon-
ding relay will be switched on and off as usual.
In order to reduce the number of switching pro-
cesses for high effi ciency pumps, a relay over-
run can be effected by setting the parameter
to 2. The corresponding relay will then remain
switched on for an hour after the switch-off con-
ditions have been fulfi lled. The overrun will be
effected after a manual mode switch-off, too.
