Thermostat Connection

Consult the thermostat manufacturer’s instructions for proper wiring detail.

IMPORTANT

WarmlyYours requires all electrical connections be made by qualiﬁ ed personnel and in accordance with the Local

Electrical Codes or National Electrical Code (NEC) and all applicable local ordinances.

Each cold lead is covered with a grounding braid. Ensure that the cold lead braids are directly connected to electrical

ground – DO NOT CUT THE GROUND BRAIDS. If the ground braids are not connected to electrical ground there will be

a risk of electrical short circuit, overheating or electrical shock.

We recommend installing the thermostat into a 4x4, 2 gang, metal box with a single gang mud ring. A circuit protected by

a ground fault protection device must be used to power mats connected through a relay.

Only connect the mat to the rated voltage. DO NOT use higher voltages as the increased current will cause the mat to

overheat possibly resulting in death or injury from electrical shock or ﬁ re, mat failure, improper operation or ﬂ oor damage.

Thinset and grout materials have cure times, review the recommended cure time from each manufacturer and do not

energize the mat until the materials have fully cured. This cure time may be as long as 28 days.

OPERATIONAL NOTES

The wire spacing on each WarmlyYours mat is custom designed, power output will vary from 12-14.5 W/ft2.

Each ﬂ oor is unique and will heat at a different rate, as such, it may take 1-3 hours to reach the optimum temperature,

possibly longer under certain conditions.

WarmlyYours recommends using a thermostat to regulate ﬂ oor temperature. WarmlyYours offers a programmable

thermostat which allows the mats to be automatically shut off at night or when you are away from home.

If the overall ﬂ oor surface feels unusually hot when the system is energized, or if the circuit breaker trips when the system

is energized, the mat may be damaged. De-energize the system immediately and contact WarmlyYours. Never bypass a

tripped ground fault device.
