Questions answered in these manuals
What temperature range does the QAE22 sensor measure?
The sensor measures temperatures from –30 °C to +130 °C.
From: Siemens QAE22 Insert Type Temperature Sensor User Manual
How should the sensor be installed for supply water temperature control?
If the pump is on the supply line, install the sensor directly behind the pump; if the pump is on the return line, install it 1.5–2 m after the mixing valve.

When is a flat‑seal protection sleeve required for the QAE22 sensor?
A flat‑seal protection sleeve must be used when the rated pressure exceeds PN10 or the temperature exceeds 100 °C.
From: Siemens QAE22 Insert Type Temperature Sensor User Manual
What is the minimum insertion length for the sensor?
The insertion length must be at least 50 mm.
How should the QAE22.2 sensor be tightened during installation?
Rotate the nut 1½ turn until strong resistance, loosen it, then tighten an additional ¼ turn.
