It is an \u003cstrong\u003eNTC (Negative Temperature Coefficient) sensor\u003c\/strong\u003e, a type of semiconductor sensor whose resistance decreases as temperature increases. This technology offers a fast response time and high precision in low temperature ranges, exactly what an antifreeze device needs to react instantly to winter temperature drops.\u003c\/p\u003e\n\n\u003cp\u003eInstalled in the pool water, outside the technical room, or directly on the plumbing, this sensor continuously transmits the temperature measurement to the DHG-2 box. As soon as the programmed trigger threshold is reached, the box automatically activates the \u003cstrong\u003efiltration pump in forced operation\u003c\/strong\u003e, preventing ice formation in the pipes and protecting your pool equipment from frost damage.\u003c\/p\u003e\n\n\u003ch2\u003eWhy and when to replace the sensor of your DHG-2 box?\u003c\/h2\u003e\n\n\u003cp\u003eOver time and successive freeze\/thaw cycles, the NTC sensor can lose precision, provide inconsistent measurements, or stop working entirely. The \u003cstrong\u003eE2 error code\u003c\/strong\u003e displayed on the digital screen of the DHG-2 box specifically indicates a temperature sensor fault. If you see this code or if your box no longer triggers filtration correctly despite low temperatures, replacing the sensor is the first action to take.\u003c\/p\u003e\n\n\u003cp\u003eTo check if your sensor is actually defective, CCEI recommends unplugging it and then plugging it back in. If the E2 error persists after this manipulation, the sensor must be replaced. The official reference to order is \u003cstrong\u003eMPCP0314\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eSimple and quick installation, without system modification\u003c\/h2\u003e\n\n\u003cp\u003eReplacing the sensor does not require any professional intervention. Simply disconnect the old sensor from the DHG-2 box's terminal block and plug in the new one in its place. The supplied \u003cstrong\u003e2-meter cable\u003c\/strong\u003e is suitable for most technical room configurations. If the distance between the box and the measurement point is greater, the cable can be extended using appropriate connectors (Wago type or terminal block), up to a maximum of \u003cstrong\u003e50 meters\u003c\/strong\u003e as recommended by CCEI.\u003c\/p\u003e\n\n\u003cp\u003eThe sensor can be positioned in three configurations: immersed in the pool water to measure water temperature, installed outside the technical room to measure ambient air temperature, or attached to the plumbing of the filtration circuit. In all cases, it is essential to avoid artificial heat sources (direct sun exposure, proximity to a radiator) that would distort the measurement.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications of the MPCP0314 NTC sensor\u003c\/h2\u003e\n\n\u003cp\u003eThis sensor is an \u003cstrong\u003eNTC thermistor\u003c\/strong\u003e, meaning a passive sensor whose electrical resistance varies with temperature. Unlike linear Pt100 sensors, the NTC offers significantly higher sensitivity at low temperatures, making it particularly suitable for detecting frost risk. The 2-meter connecting cable connects directly to the DHG-2 box's terminal block. The sensor is designed to withstand winter outdoor conditions: humidity, negative temperatures, and prolonged exposure.\u003c\/p\u003e\n\n\u003ch2\u003eCompatibility: exclusively for CCEI DHG-2 frost protection box\u003c\/h2\u003e\n\n\u003cp\u003eThe MPCP0314 sensor is \u003cstrong\u003especifically designed for the CCEI DHG-2 box\u003c\/strong\u003e, the electronic thermostat model with digital display. It is not compatible with the DHG-A box (mechanical thermostat model) or with other frost protection boxes from other brands. If you own a DHG-A, consult the CCEI documentation to identify the appropriate sensor for your model.\u003c\/p\u003e\n\n\u003ch2\u003eThe DHG-2 box: reminder of operation\u003c\/h2\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCCEI DHG-2 frost protection box\u003c\/strong\u003e is an active winterizing device that controls the filtration pump based on the outdoor or water temperature. Its electronic thermostat allows the trigger threshold to be set between \u003cstrong\u003e-5 °C and +5 °C\u003c\/strong\u003e. When the sensor detects a temperature below the programmed threshold, the box forces the filtration to start. Water circulation in the pipes prevents ice formation and allows warmer water from the bottom of the pool to be recovered via the main drain, thereby warming the surface water.\u003c\/p\u003e\n\n\u003cp\u003eBeyond its winter function, the DHG-2 can also be used in summer to trigger filtration above a certain temperature, thus limiting the development of microorganisms and algae in the pool.\u003c\/p\u003e\n\n\u003ch2\u003eWhy choose an original CCEI part?\u003c\/h2\u003e\n\n\u003cp\u003eUsing the official CCEI replacement sensor guarantees \u003cstrong\u003eperfect compatibility\u003c\/strong\u003e with the DHG-2 box's electronics, measurement values calibrated for the box's thermostat, and durability suitable for use in a pool environment. A generic NTC sensor could have a different resistance curve, leading to measurement discrepancies and imprecise triggering of frost protection — a risk best avoided for the protection of your equipment.\u003c\/p\u003e","brand":"CCEI","offers":[{"title":"Default Title","offer_id":52139681972561,"sku":"MPCP0314","price":12.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/5880\/9425\/files\/e7a014bd2288a7bdbe6aed89e7aa038a.png?v=1777387105","url":"https:\/\/www.poolplanet.com\/en\/products\/sonde-de-temperature-pour-dhg-2-ccei","provider":"Pool Planet","version":"1.0","type":"link"}
