QAA... room temperature sensors with sensing element LG-Ni 1000 QAA24 Sensing of room temperature in heating plants for: • Room temperature influence for the heating curve • Limitation of the room temperature • Room temperature compensation or optimization • Display of actual room temperature QAA64 Sensing of room temperature in heating plants where the sensor needs to be protected against damage or destruction by people.
PAGE 3
Installation notes Depending upon the application, all room temperature sensing devices should be located as follows: • For maximum limitation: in the room with the largest heat gains • For minimum limitation and control: in the room that cools down the quickest Room temperature sensors and room units should be sited on an inner wall of the reference room.

QAE... immersion temperature sensors with sensing element LG-Ni 1000 QAE22A QAE22.5A QAE22.2A QAE26… Immersion temperature sensors are designed for insertion into the heating pipe or storage tank (typically via a protection pocket). Use QAE22 when it is not possible to fit a QAD22 strap-on device.
PAGE 6
Installation notes The QAK… sensor is for direct immersion into the medium to be controlled and screws into the threaded hole provided for that purpose. Use a heat-resistant seal ensuring a tight fit. QLS...

Controller summary SIGMAGYR The success story of the SIGMAGYR® heating controller, which ranges from simple analog devices to communicative multifunctional controllers, began with its introduction over 30 years ago. In the 3 decades since their introduction, the original standalone controllers have evolved into a comprehensive range of small but intelligent controllers that cover the requirements of virtually every type of heating system and building.
