{"product_id":"qbp497670","title":"Vimar Surface Battery Timer Thermostat, For Heating and Air-Conditioning Systems, 5(2)A 250V, Daily\/Weekly Programming","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Vimar 01910 is a surface-mounted electronic timer thermostat for ON\/OFF control of heating and air-conditioning systems. It uses a 5(2) A 250 V~ change-over relay output and runs on 2 AA LR6 1.5 V batteries, so the thermostat itself does not need a mains feed at the mounting point. Daily and weekly scheduling is built in, with 15-minute programming steps for routine temperature changes through the week.\u003c\/p\u003e\u003cp\u003eFor boat interiors, this format makes sense when you want scheduled climate control in an enclosed cabin, saloon, or wheelhouse without pulling a separate supply to the thermostat position. The display shows ambient temperature, day, time, operating status, and the active daily profile. It also supports heating and cooling selection, adjustable hysteresis from 0.1 °C to 1 °C, and an antifreeze setting from +4 °C to +15 °C.\u003c\/p\u003e\u003cp\u003eThis is an interior-use control. The housing is IP30 and the stated operating temperature is 0 °C to +40 °C, so it belongs in dry spaces away from spray, washdowns, and exposed helm positions.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eON\/OFF ambient temperature control for heating and air-conditioning systems\u003c\/li\u003e\n\u003cli\u003e5(2) A 250 V~ change-over relay output for the control circuit\u003c\/li\u003e\n\u003cli\u003eDaily and weekly programming with 15-minute time steps\u003c\/li\u003e\n\u003cli\u003ePowered by 2 AA LR6 1.5 V batteries, with no mains feed required at the thermostat location\u003c\/li\u003e\n\u003cli\u003eAdjustable hysteresis from 0.1 °C to 1 °C and thermostat operating range from +5 °C to +35 °C in heating or cooling mode\u003c\/li\u003e\n\u003cli\u003eAntifreeze mode adjustable from +4 °C to +15 °C for low-temperature protection\u003c\/li\u003e\n\u003cli\u003eSurface-mount format with fixing options for direct wall mounting or boxes with 60 mm or 83.5 mm screw spacing\u003c\/li\u003e\n\u003cli\u003eIP30 enclosure for dry interior installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis thermostat is offered in three color configurations.\u003c\/p\u003e\u003cp\u003eThe function, programming format, relay rating, battery supply, and surface-mount format stay the same across the range.

On board, that usually means a cabin bulkhead or enclosed living area rather than a spot near companionways, direct sun, galley heat, vents, or doors that open often. Those locations can distort the temperature reading and make the schedule less useful in day-to-day use.\u003c\/p\u003e\u003cp\u003eThe base has four fixing slots for direct wall mounting with 6 mm screws and wall plugs, or for mounting to inset boxes with 60 mm or 83.5 mm screw centres. It should be installed in a dry, low-dust area.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThis unit is meant to switch the control side of a climate system, not to power the heating or cooling equipment directly. It can be used on control circuits for applications such as burners, circulation pumps, air-conditioning control circuits, solenoid valves, and motor-operated valves when the circuit matches the relay rating and the system layout. On a boat, that makes it relevant for enclosed accommodation spaces with a heater or air-conditioning setup that accepts a simple switched thermostat input.\u003c\/p\u003e\u003cp\u003eThe thermostat itself operates on 3 V d.c. from two AA batteries and battery life is rated up to one year. Because the control electronics are battery powered, low battery condition matters for continuity of operation, especially on boats left unattended between trips.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis is a good match for boats that need scheduled cabin temperature control in an enclosed interior without adding a power feed to the thermostat location. It suits cruisers, passagemakers, and liveaboard setups where the heating or air-conditioning system already has a compatible control circuit. It is less suitable for open cockpit, flybridge, or deck locations where moisture and weather exposure are part of normal use.\u003c\/p\u003e","brand":"Vimar","offers":[{"title":"Anthracite","offer_id":52371062718645,"sku":"QBP497670-V1","price":220.07,"currency_code":"USD","in_stock":false},{"title":"Silver","offer_id":52371062751413,"sku":"QBP497670-V2","price":203.3,"currency_code":"USD","in_stock":false},{"title":"White","offer_id":52371062784181,"sku":"QBP497670-V3","price":203.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1320198_qbp497670.jpg?v=1774058526","url":"https:\/\/www.qualityboatparts.com\/products\/qbp497670","provider":"Quality Boat Parts","version":"1.0","type":"link"}
