Whisper Relay Control Box

Every HYS RED package includes our prewired Whisper

Relay Control Box, sized to the number of lights or radiant 

heating panels in your studio. The control

box contains prewired silent modular contactors that

supply power to the panels — providing reliable, near-

silent operation in a UL-Listed watertight enclosure.

Electricians connect the 208–240V power to the relays,

with each relay supporting up to 5 heating panels per

circuit
