OpenTherm is a \u0026quot;point-to-point\u0026quot; communication, where the thermostat is usually the \u0026quot;master\u0026quot; and the heat generator is the \u0026quot;slave\u0026quot;.

Sending status reports and requesting information between the two devices is possible. However, the most common command relates to the regulation of the boiler temperature. When the heating system receives the setpoint temperature request, it begins to modulate (increase or reduce the heating output) in order to reach and maintain the setpoint temperature. The room thermostat constantly recalculates the boiler temperature to keep the room temperature at the setpoint. This leads to higher energy efficiency.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003e\u003cspan\u003eSpecial features:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003econtinuous control of three mixing valves\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003econtrol of the DHW pump\u003c\/li\u003e\n\u003cli\u003esupports a solar system\u003c\/li\u003e\n\u003cli\u003ereturn temperature protection\u003c\/li\u003e\n\u003cli\u003eweather and weekly control\u003c\/li\u003e\n\u003cli\u003einexpensive from solar-more\u003c\/li\u003e\n\u003cli\u003etwo configured potential-free outputs\u003c\/li\u003e\n\u003cli\u003etwo configured voltage outputs\u003c\/li\u003e\n\u003cli\u003etwo configurable 0-10V outputs (PLUS VERSION)\u003c\/li\u003e\n\u003cli\u003esolar pump output with PWM signal (PLUS VERSION)\u003c\/li\u003e\n\u003cli\u003ecascade control of 4 heat generators (PLUS VERSION)\u003c\/li\u003e\n\u003cli\u003ecommunication with three two-point room thermostats\u003c\/li\u003e\n\u003cli\u003ecommunication with a room thermostat with RS communication\u003c\/li\u003e\n\u003cli\u003eextension of an EU-505 or EU-WIFI-RS module\u003c\/li\u003e\n\u003cli\u003econtrol of two additional valves using additional modules EU-I-1-M, EU-I-1, EU-i-1 WW\u003c\/li\u003e\n\u003cli\u003eprogram version update via a USB port\u003c\/li\u003e\n\u003cli\u003eOpenTherm (OT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan\u003eTechnical data:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eBoiler temperature setting range - from 10 to 99°C\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFloor temperature setting range - from 10 to 50°C\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHot water temperature setting range - from 5 to 80°C\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMains voltage 230V \/ 50Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRated load of outputs 0.5A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFuse 6.3A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTemperature resistance of sensors - from -30 to 99°C\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eEquipment\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eLCD display\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBoiler temperature sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFlow temperature sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReturn temperature sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSolar sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOutdoor sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWall mounting\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSensors of type KTY 81-210 with a diameter of 5 mm are used here\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eScope of delivery:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eEU-i-3 PLUS controller\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e5 sensors in total + 1 outdoor sensor\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eDownload\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/DE_EU-i-3Plus_OT.pdf?v=1732530048\" title=\"Master V3 Plus operating instructions\" rel=\"noopener\" target=\"_blank\" aria-label=\"Besuchen Sie eine Webseite über Master V3 Plus Bedienungsanleitung\"\u003e\u003cspan\u003eOperating instructions\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Master","offers":[{"title":"Vaiketitel","offer_id":53515558093148,"sku":"EUi3plus","price":445.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/master-v3-plus-eu-i-3-plus-heizungsregelung-fur-3-heizkreise-gemischt-und-ungemischt-9142556.jpg?v=1770692367","url":"https:\/\/ee.gemashop.de\/en\/products\/master-v-3-plus-eu-i-3-plus-open-therm-kutteregulaator-3-kuttekontuuri-jaoks","provider":"GEMA Shop","version":"1.0","type":"link"}
