Overview

The Vimar IoT Dial Thermostat is a flush-mount room thermostat for AC-powered heating and cooling control, with a 100-240 V AC supply, a relay output rated at 5(2) A 240 V~, and Bluetooth 5.0 for the View Wireless mesh system.

It fits a 2-module installation and works in ON/OFF or PID control mode. There is also an input for an external resistance temperature sensor, which is useful when the thermostat needs to read temperature away from the mounting point or when cabin conditions change quickly.

For marine use, this unit makes sense in protected interior spaces such as cabins, saloons, crew areas, and enclosed wheelhouses where climate control is part of an AC system. With IP30 protection and an operating range of 0 C to +40 C, it is meant for indoor locations rather than open deck, washdown, or other exposed areas.

Key features

• 100-240 V AC power supply with a clean relay output rated at 5(2) A 240 V~
• Supports both heating and air conditioning control in ON/OFF and PID modes
• Bluetooth 5.0 connectivity for integration into the View Wireless mesh system
• Input for an external resistance temperature sensor for installations where the sensing point needs to be moved
• Flush-mounted 2-module format with white LED backlighting and adjustable brightness
• Works with Eikon, Arké, and Plana cover plates, and can be installed in the Idea range with frame 16723
• IP30 indoor protection, which suits enclosed spaces on board rather than wet or exposed mounting positions

Variants

This thermostat is offered in multiple finish options under the same IoT dial thermostat family.

The visible finish changes between variants. The control format, 2-module size, power supply, relay rating, View Wireless connectivity, and heating and cooling functions stay the same across these listed versions.

• VM02973: Grey finish. This gives the thermostat a darker look that blends well with modern cabin panels and technical interiors.
• VM02973.M: Metal finish. This version shifts the appearance toward a brighter, more decorative front without changing the control format.
• VM02973.N: Silver finish. This keeps the same thermostat layout with a lighter finish that suits contemporary switch and plate combinations.

Installation and setup

This is a flush-mounted thermostat with 3-wire or 4-wire connection, so it should be matched to the vessel's AC HVAC control circuit before purchase. The relay contact is intended for control duties within the stated rating, and it is not a direct controller for low-voltage DC loads such as 12 V or 24 V DC fan circuits unless the wider system is built around the correct interface or relay logic.

Configuration is handled through the View Wireless app. The thermostat can also use an external temperature sensor, and sensor cable length can run up to 10 m when installed with suitable twisted cable, which helps when the best sensing point is not the same as the best mounting point.

Compatibility and fit

This model is a good match for boats and yachts using Vimar switching infrastructure in interior living spaces, especially where the owner wants climate control to sit neatly alongside other 2-module controls. It also suits refit work where a smart thermostat is needed for an enclosed zone and the rest of the system already uses, or plans to use, View Wireless devices.

Before fitting, check the available wall box depth, the compatible cover plate series, and the HVAC control method on board. The thermostat is meant for indoor ambient temperature control, so it should be mounted away from spray, direct weather, and other positions where moisture or outdoor temperature swings would affect accuracy.
