Sending status reports and requesting information between the two devices is possible. However, the most common command relates to boiler temperature control. When the boiler receives the setpoint temperature request, it begins to modulate (increase or decrease the heating output) to reach and maintain the setpoint temperature. The room thermostat continuously recalculates the boiler temperature to keep the room temperature at the setpoint. This results in higher energy efficiency.\u003c\/span\u003e\u003c\/div\u003e  \u003cdiv\u003e  \u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e  \u003c\/div\u003e  \u003cdiv\u003e  \u003ch3\u003e\u003cspan\u003eSpecial features:\u003c\/span\u003e\u003c\/h3\u003e  \u003cdiv\u003e  \u003cul\u003e  \u003cli\u003e\u003cspan\u003eContinuous control of three mixing valves\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003eHot water pump control\u003c\/li\u003e  \u003cli\u003esupports a solar power system\u003c\/li\u003e  \u003cli\u003eReturn temperature safety device\u003c\/li\u003e  \u003cli\u003eWeather and weekly schedule\u003c\/li\u003e  \u003cli\u003eaffordable by solar-more\u003c\/li\u003e  \u003cli\u003etwo configured potential-free outputs\u003c\/li\u003e  \u003cli\u003etwo configured voltage outputs\u003c\/li\u003e  \u003cli\u003etwo configurable 0-10V outputs (PLUS VERSION)\u003c\/li\u003e  \u003cli\u003eSolar pump output with PWM signal (PLUS VERSION)\u003c\/li\u003e  \u003cli\u003eCascade connection of 4 heat generators (PLUS VERSION)\u003c\/li\u003e  \u003cli\u003eCommunication between three two-point room thermostats\u003c\/li\u003e  \u003cli\u003eCommunication with a room thermostat with RS communication\u003c\/li\u003e  \u003cli\u003eExpansion of an EU-505 or EU-WIFI-RS module\u003c\/li\u003e  \u003cli\u003eControl of two additional valves using additional modules EU-I-1-M, EU-I-1, EU-i-1 WW\u003c\/li\u003e  \u003cli\u003eUpdating the program version via a USB connection\u003c\/li\u003e  \u003cli\u003eOpenTherm (OT) \u003c\/li\u003e  \u003c\/ul\u003e  \u003c\/div\u003e  \u003ch3\u003e\u003cspan\u003eTechnical data:\u003c\/span\u003e\u003c\/h3\u003e  \u003cul\u003e  \u003cli\u003e\u003cspan\u003eBoiler temperature setting range - from 10 to 99°C\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eFloor temperature setting range - from 10 to 50°C\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eHot water temperature setting range - 5 to 80°C\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eMains voltage 230V\/50Hz\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eRated load of the outputs 0.5A\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003e6.3A fuse\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eTemperature resistance of the sensors - from -30 to 99°C \u003c\/span\u003e\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch3\u003e\u003cspan\u003eEquipment\u003c\/span\u003e\u003c\/h3\u003e  \u003cul\u003e  \u003cli\u003e\u003cspan\u003eLCD display\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eBoiler temperature sensor\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eFlow temperature sensor\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eReturn temperature sensor\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003esolar sensor \u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eOutdoor sensor\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003ewall mounting\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eKTY 81-210 type sensors with a diameter of 5mm are used here.\u003c\/span\u003e\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch3\u003e\u003cspan\u003eScope of delivery:\u003c\/span\u003e\u003c\/h3\u003e  \u003cdiv\u003e  \u003cul\u003e  \u003cli\u003e\u003cspan\u003eEU-i-3 PLUS control unit\u003c\/span\u003e\u003c\/li\u003e  \u003cli\u003e\u003cspan\u003eA total of 5 sensors + 1 external sensor\u003c\/span\u003e\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch3\u003e\u003cspan\u003eDownload\u003c\/span\u003e\u003c\/h3\u003e  \u003cul\u003e  \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 Bedienungsanleitung\" rel=\"noopener\" target=\"_blank\" aria-label=\"Besuchen Sie eine Webseite über Master V3 Plus Bedienungsanleitung\"\u003e\u003cspan\u003eUser manual\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e  \u003c\/ul\u003e  \u003c\/div\u003e  \u003c\/div\u003e","brand":"Master","offers":[{"title":"Default Title","offer_id":53515558093148,"sku":"EUi3","price":452.55,"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:\/\/ie.gemashop.de\/products\/master-v-3-plus-eu-i-3-plus-open-therm-heating-control-for-3-heating-circuits","provider":"GEMA Shop","version":"1.0","type":"link"}
