Product Description for Siemens BPZ:RLE162 Wall‑Mount Immersion Temperature Controller
1. Product Overview
BPZ:RLE162 (Order code RLE162) is a new‑original compact wall‑mounted and pipe‑installable electronic controller under Siemens Synco 100 series for HVAC and heating‑water control systems. This integrated unit combines LG‑Ni1000 immersion temperature sensor, built‑in PI controller, manual set‑point adjustment slider and control electronic components in one single housing. It runs on AC24 V control power and outputs DC 0‑10 V analogue signals to drive mixing valves, circulating pumps and modulating actuators for hot‑water circuits, chilled‑water pipelines and heating‑loop systems. It supports external input signals for remote set‑point modification, outside‑temperature compensation and temperature limitation. Besides analogue outputs, it provides an extra relay switching contact for auxiliary equipment control such as alarm triggers or pump start‑stop commands. It can be installed either on control‑cabinet walls or directly mounted to pipelines via a G½A threaded immersion sleeve for heating‑system applications in residential buildings, hotels, factory workshops and district heating stationshit.sbt.si…. It works independently without relying on higher‑level building management system and complies with European HVAC industry standards.
2. Main Functions
- PI Proportional‑Integral Temperature Regulation
Built‑in PI algorithm automatically adjusts DC 0‑10 V analogue outputs Y1 and Y2 to change opening of water‑mixing valves, maintaining stable flow‑water temperature. Users can select heating mode or cooling mode by internal configuration settings.
- Multi‑Input Signal Processing
It receives sensor signals from built‑in immersion probe and external inputs: remote set‑point potentiometer, outside‑air temperature sensor and 0‑10 V limitation signals to realize weather‑compensated temperature adjustment and upper/lower temperature limit protection.
- Adjustable Switching Relay Output
The Q13‑Q14 relay contact activates when heating or cooling demand exceeds 5% of control span. It can control circulation pumps, auxiliary heaters and fault‑indication devices. The contact resets automatically after 12 minutes with zero demand.
- Manual Operation and Test Mode
The front‑side slider enables manual set‑point configuration. Under test mode indicated by flashing LED, users manually drive actuators to check equipment running status during commissioning without connecting upper‑level controllers. Solid‑on LED means normal working statehit.sbt.si….
- Legionella Protection Function
When parameter is enabled, the controller triggers high‑temperature periodic disinfection cycles for domestic hot‑water circuits to suppress legionella bacteria in hot‑water storage tanks.
- Flexible Installation Options
Two installation ways are available: wall‑mount installation inside control cabinets or immersion installation on water pipes with stainless‑steel probe; stainless‑steel sensing rod complies with DIN‑17440 standard for long‑term contact with hot‑water mediumhit.sbt.si….
- Short‑Circuit and Over‑Temperature Protection
Internal circuit protection prevents electronic damage caused by short‑circuited outputs and over‑high ambient temperature to extend service life.
