Wiring

The tested and approved Warmup radiant floor heating element comes with a 30-year warranty. Every heater is individually checked, including a test for electrical strength at 3000V, before it leaves the factory.
Thermostat Location
The Warmup Thermostat (sold separately) can be installed within the same room as the heater, outside the room, or even in a cupboard, because the heating has the option of being monitored by the floor probe underneath the floor or by the air temperature (or both!).
Electrical Installation
All electrical work should be undertaken by a qualified electrician in accordance with local building and electrical codes, section 62 of the Canadian Electrical Code (CEC) Part 1, and the National Electrical Code (NEC), especially article 424, Part J of the NEC, ANSI/NFPA 70.
The Warmup DUALUDG Thermostat incorporates a GFCI (Ground Fault Circuit Interrupter)
We recommend that your Warmup heating system be the only load on the electrical circuit supplying power to the heaters. They must always be installed within current NEC and local codes. Some local codes require separate conduit for the low and high voltage wires. If so, you may require conduit for the cold lead wires that supply power to the system and separate conduit for the thermostat sensor wire. It is possible to run one or more than one electric floor heating system from an existing circuit but you should consult with an electrician to determine whether or not the circuit can handle the load and whether local codes allow for this. The Warmup DUAL-UDG Thermostat should be installed in a 4" x 4" deep square box with single gang mud ring. The wiring to the thermostat should be run into the wall and, if required by local code, be protected by plastic conduit.
Electrical Considerations for 120 & 240VAC Systems
If the area to be heated exceeds 130 sq ft, then you can either install multiple thermostats; use a master thermostat & relay configuration or install a Warmup 240V system (Note: the 240V system runs at a higher voltage but lower amperage).
The Warmup DUALUDG
The Warmup USTAT has a resistive load of 15 amps and may be used with both 120V and 240V systems. If you want to control more than 15 amps worth of heating via a single thermostat you will need to use Warmup's master thermostat & relay configuration. Instead of using the USTAT, a different model of master thermostat is used to control individual relay units (each capable of switching up to a 15 amp load, and each containing its own GFCI). The relays require their own separate electrical feed, and up to 10 relays can be daisy-chained to a single master unit via low voltage.
Floor Probe
Fit the system's temperature-sensing floor probe in the center of two runs of the Warmup electric heating wire, approximately 12" from the wall. This ensures that the tip of the sensor receives a representative reading. You may extend the probe wire up to 150 feet using a wire of similar grade.
