• AEROGYR™ RWI65...
When using the QAA26 in connection with the RWI65..., the latter must be set to
the setpoint setting range "Heating". In that case, the setpoint of "Heating" on the
RWI65... must be set to 20 °C and additionally, the following must be set:
– Data point 44 to –15 K and data point 45 to + 15 K for RWI65.01
or
– Commissioning data point 9 to –15 K and commissioning data point 10 to +15 K
for RWI65.02
• When using the QAA27, the setpoint adjustment knob must be set to its centre posi-
tion. Additionally, the following must be set:
– Data point 44 to –4 °C and data point 45 to +5 °C for RWI65.01. The offset at data
point 50 must be corrected until data point 2 has value 0.
– Commissioning data point 9 to –15 °C and commissioning data point 10 to +15 °C
for RWI65.02. The offset at commissioning data point 15 must be corrected until
normal data point 2 has value 0.

• POLYGYR
RCM6..., RCE6... and RWF...
For averaging with two temperature sensors and a POLYGYR
sors need to be connected in series and the controller requires a setting range insert
AZW61.119-tx50.
If the QAA25 is used with a shift controller, the sensor's range (0...50 °C) is required
for calculating the authority
• CLASSIC RKN...
Setpoint adjustments via QAA27 is possible only with controllers RKN8-L, RKN88-L,
RKN-W and RKN88T.
Location: On an inner wall of the space to be heated or air conditioned. Not in reces-
ses, shelves, not behind curtains, not opposite or near heat sources.
The unit must not be exposed to direct solar radiation.
The end of the conduit at the sensor must be sealed to prevent false measurements
due to draughts through the conduit.
The permissible ambient conditions should be observed.
Installation instructions are printed on the packing.
