(FOR MulTiPlE MAT inSTAllATiOnS)
The LATICRETE Floor Warming Thermostat is rated for 15 Amps and is
®
equipped with an Internal GFCI. If the total amperage of a multiple mat
system exceeds 15 Amps:
A. The LATICRETE Floor HEAT mats and controls should be connected
through a contactor in accordance with all NEC and local electrical
codes.
B. The heating elements must be protected by a separate GFCI. The
LATICRETE Floor Warming Thermostat will no longer be providing the
fault protection due to the use of the contactor.
C. Use a GFCI Breaker capable of handling the total load in accordance
with NEC and local codes.
OPTiOnAl: The installation layout may be designed to split the area
into different zones. Separate controls may then be used for each zone.
This would eliminate the need for a contactor. however, the Total
Amperage for EACh control should nOT exceed 15 Amps.
