When designing a project using Warmset by Penrod, special attention is need-
ed when connecting multiple mats or large single mats in a wet area. Class A
thermostats have GFCI protection and will trip when the cd (current di
ff
eren-
tial) exceeds 5 mA (milliamps).
Given the e
ffi
cient nature of the Warmset by Penrod product, there may be
times where you will exceed the current di
ff
erential or 5 mA before you will
exceed the 15 amp maximum on a single load compared to most wired heat-
ing products on the market. Warmset by Penrod o
ff
ers relays in both 5 mA (for
all areas-including wet) and 15 mA (for non wet areas) should the user want to
use multiple mats or for larger projects while still using one thermostat. please
refer to cd value column for each mat.
