ZONE CONTROLLER
SLAB STAT
Sensing and controlling the system based upon radiant fl oor surface temperature
or the concrete mass has very positive benefi ts. Radiant fl oor air stat in the same
area as a forced air roomstat presents serious control problems. A remote sensing
slab stat for the radiant fl oor removes this issue.
Remote sensing slab stat is required for storage applications.
