Our Services: Meet the Cozy Core

A view of a living room with a recessed convector radiator underneath large windows. There is a through wall heat pump next to it. There is a small device attached to the radiator.

What is it?

The Core is a convector radiator solution that balances building heating, enables temperature controls to residents, and provides heating cost savings for facility managers. The Core is comprised of two parts: a digital temperature controller and a small, internal fan. The digital temperature controller attaches to the outside of your radiator enclosure and communicates with a fan that is placed inside of the enclosure, which we insulate. The digital controller has a built in temperature sensor, so when you set your desired temperature the sensor will communicate to the fan to release hot air into the room.

POWER REQUIREMENTS:

Each unit is operated by a single fan requiring 12v DC power. Units consume less than 12 Watts of power at max draw (1A at 12V). This power can be provided via an included AC adaptor, which requires a standard 110VAC outlet within 10 ft of the fan unit, or 12V DC power can be brought to the unit from a UL-Certified building source. If an outlet is greater than 10ft from the unit, an extension cable of AWG 22 or larger, maximum 50ft in length, can be used to bridge the distance.

NETWORK REQUIREMENTS:

Each unit contains a wireless radio, that requires proximity to an associated network for communication, which will be provided by Kelvin before system installation.
