Using The Efma System - Reznor EFMA Installation Manual

4.9 Using the EFMA System

• The EFMA floor heating system is now ready for use. However, before turning on
the system, make sure the curing period specified by the cement or binder manufac-
turer has expired. Adjust the thermostat's temperature based on your needs and
desired level of comfort.
5. IMPORTANT!
The EFMA system must be controlled by a temperature control system.
If EFMA is to be used for floor warming, an electronic floor temperature control
featuring a floor sensor is recommended to ensure heat levels never exceed the floor
covering's maximum temperature tolerance.
If the system is to be used for radiant heating, the room thermostat controls heat and
is reacting to room and not floor temperature therefore a floor covering with greater
temperature resistance must be used.
The room temperature control and floor temperature sensor must never be installed
where they will be exposed to sunlight or air drafts.
IMPORTANT!
The EFMA floor heating system must be connected to a ground fault circuit inter-
rupter (GFCI) when installed in a bathroom. REZNOR strongly recommends the use
of a GFCI in all rooms featuring the EFMA system.
Recommended temperature regulation devices:
1- Thermostat with floor sensor and integrated GFCI (floor warming only).
2- Rheostat dimmer switch with a GFCI.
3- Electronic ambient thermostat with a GFCI (radiant room heating).
