Under Circuit 2 makes settings for the first shunted
circuit, E12. Connection board XB1 for this circuit is part
of the heat pump. Other circuits are displayed only if
they are connected via accessory IVT mixing valve
module 1000. The same settings apply to these as for
Circuit 2 .
Mixing valve operating mode
B
Set operating mode for the mixing valve according to
the capacity and current needs of the valve.
B
For circuit E13 in system solutions ( Page 15)
Cooling must be selected.
B
For circuit E12 in system solutions ( Page 13
and 14)
Heating/Cooling must be selected, if heating/
cooling operation is wanted.

Cooling
The settings are the same as the primary cooling circuit,
except that
Acknowledge anti-freeze sensor T32 and
Anti-freeze limit T32 are not displayed. These menus
apply in general.
Settings for dew point sensor apply to room transducer
for relative humidity and temperature E12.TM connected
to the heat pump. Circuit E13 (and E31) does not need
a room sensor (dew point sensor), the circuits are
condensation insulated.

Tab. 32 Mixing valve running time
CAUTION: Change the value for the mixing
valve running time to the value specified on
the mixing valve. If the time is not specified
on the mixing valve: move the mixing valve
manually ( Chapter 9.2) and measure how
long it takes to reach the fully open position
from the fully closed position (the mixing
valve audibly closes and the end position
switch kicks out).
