Product Description for Siemens BPZ:RLE162 Wall\u2011Mount Immersion Temperature Controller<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
BPZ:RLE162 (Order code RLE162) is a new\u2011original compact wall\u2011mounted and pipe\u2011installable electronic controller under Siemens Synco 100 series for HVAC and heating\u2011water control systems. This integrated unit combines LG\u2011Ni1000 immersion temperature sensor, built\u2011in PI controller, manual set\u2011point adjustment slider and control electronic components in one single housing. It runs on AC24 V control power and outputs DC 0\u201110 V analogue signals to drive mixing valves, circulating pumps and modulating actuators for hot\u2011water circuits, chilled\u2011water pipelines and heating\u2011loop systems. It supports external input signals for remote set\u2011point modification, outside\u2011temperature 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\u2011stop commands. It can be installed either on control\u2011cabinet walls or directly mounted to pipelines via a G\u00bdA threaded immersion sleeve for heating\u2011system applications in residential buildings, hotels, factory workshops and district heating stationshit.sbt.si…. It works independently without relying on higher\u2011level building management system and complies with European HVAC industry standards.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. PI Proportional\u2011Integral Temperature Regulation\n
    <\/div>\n

    Built\u2011in PI algorithm automatically adjusts DC 0\u201110 V analogue outputs Y1 and Y2 to change opening of water\u2011mixing valves, maintaining stable flow\u2011water temperature. Users can select heating mode or cooling mode by internal configuration settings.<\/li>\n

  2. Multi\u2011Input Signal Processing\n
    <\/div>\n

    It receives sensor signals from built\u2011in immersion probe and external inputs: remote set\u2011point potentiometer, outside\u2011air temperature sensor and 0\u201110 V limitation signals to realize weather\u2011compensated temperature adjustment and upper\/lower temperature limit protection.<\/li>\n

  3. Adjustable Switching Relay Output\n
    <\/div>\n

    The Q13\u2011Q14 relay contact activates when heating or cooling demand exceeds 5% of control span. It can control circulation pumps, auxiliary heaters and fault\u2011indication devices. The contact resets automatically after 12 minutes with zero demand.<\/li>\n

  4. Manual Operation and Test Mode\n
    <\/div>\n

    The front\u2011side slider enables manual set\u2011point configuration. Under test mode indicated by flashing LED, users manually drive actuators to check equipment running status during commissioning without connecting upper\u2011level controllers. Solid\u2011on LED means normal working statehit.sbt.si….<\/li>\n

  5. Legionella Protection Function\n
    <\/div>\n

    When parameter is enabled, the controller triggers high\u2011temperature periodic disinfection cycles for domestic hot\u2011water circuits to suppress legionella bacteria in hot\u2011water storage tanks.<\/li>\n

  6. Flexible Installation Options\n
    <\/div>\n

    Two installation ways are available: wall\u2011mount installation inside control cabinets or immersion installation on water pipes with stainless\u2011steel probe; stainless\u2011steel sensing rod complies with DIN\u201117440 standard for long\u2011term contact with hot\u2011water mediumhit.sbt.si….<\/li>\n

  7. Short\u2011Circuit and Over\u2011Temperature Protection\n
    <\/div>\n

    Internal circuit protection prevents electronic damage caused by short\u2011circuited outputs and over\u2011high ambient temperature to extend service life.<\/li>\n<\/ol>\n<\/div>\n
