Installation Guide
Controlling Your System
WarmlyYours recommends a Class-A GFCI, UL/CSA/ETL or similar NRTL listed
thermostat to control the Environ™ Flex Rolls. A programmable thermostat will
allow you to set your oor warm-up time and will provide you increased energy
efciency, by programming your wake up, away, bedtime, and vacation settings.
Most wood laminate manufacturers specify that their oors should not be
subjected to temperatures in excess of 85ºF (29ºC). The only reliable way to
achieve this is to install a temperature sensor directly under the Environ™ Flex
Rolls. Check with your laminate manufacturer to see their recommendations for
installing electric radiant heat under their oors.
The WarmlyYours SmartStat™ programmable thermostat can be programmed
to the temperature recommended by the laminate manufacturer.
Professional Electric Installation
Attention: Some local codes require that a licensed electrician
complete the nal connection of the oor heating system.
The installation of electrical systems presents a risk of re and electrical shock,
which may result in personal injury. Caution should always be taken to guard
against these risks. A qualied electrician should connect Environ™ Flex Rolls to
the thermostat and/or to the electrical supply circuit. All such connections MUST
be in accordance with the National Electric Code, Canadian Electric Code, and
all local codes.
WarmlyYours strongly suggests a dedicated circuit for each system. A non-
dedicated circuit can cause nuisance tripping of the GFCI built into the thermostat.
