and set the thermostat Floor Limit temperature appropriately.

System Start Up
After all controls are installed, do not energize the system, except to briefly test operation
of all components (no longer than 10 minutes). Do not put the system into full operation
until the tile or flooring installer verifies all cement materials are fully cured (typically
two to four weeks). See mortar manufacturer’s instructions for recommended curing time.
