Water temperature is controlled by Outdoor Temperature Reset for space heating applications or a fixed setpoint for Domestic Hot Water (DHW) tank heating or industrial process heating applications. The control will also accept an analog 0-10 V (dc) signal from an Energy Management System (EMS) to control the water temperature. Boiler Equal Run Time Rotation, pump exercising and stand-by system pump operation increase boiler plant reliability. The control is tekmarNet communication compatible allowing for internet connectivity using an optional Gateway 483.\n\u003cbr\u003eFEATURES\n\u003cbr\u003eOutdoor temperature reset, programmable schedules\n\u003cbr\u003eBoiler pump(s) operation (optional), test sequence to ensure proper component operation\n\u003cbr\u003eEqual run time rotation, exercising\n\u003cbr\u003ePowered system pump output, alerts\n\u003cbr\u003eAccess levels\n\u003cbr\u003etekmarNet 4 compatible, condensing and non-condensing boiler groups\n\u003cbr\u003eDHW pump operation, DHW priority (optional)\n\u003cbr\u003eControl up to 4 modulating or on\/off boilers, primary pump sequencing\n\u003cbr\u003eWarm weather shut down, automatic boiler differential\u003c\/p\u003e\n\n\n\n\u003cp\u003e \n\u003cbr\u003e\t\t\t\t\t\t\t\t\t\n\u003cbr\u003e\t\t\t\t\t\t\n\u003cbr\u003e\t\t\t\t\t\t\n\u003cbr\u003e See All Tekmar Products\n\u003cbr\u003e\t\t\t\n\u003cbr\u003e\t\t\t\n\u003cbr\u003e Tekmar\u003c\/p\u003e","brand":"Tekmar","offers":[{"title":"Default Title","offer_id":48627733299443,"sku":"TEKMAR275","price":1100.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0021\/7587\/files\/tek275.jpg?v=1773294803","url":"https:\/\/advancedheatingsupply.com\/products\/tekmar-275-boiler-control-one-tn4-four-modulating-boiler-dhw-setpoint","provider":"Advanced Heating Supply LLC","version":"1.0","type":"link"}
