How to figure out the Kilowatt Load usage for your WarmlyYours floor heating system?

On the new touchscreen thermostat UDG4-4999, during the startup menu, users will be prompted to enter their KW load usage. Floor Load is the total wattage of the floor heating system that can be found on the installation or electrical plan. A lot of our customers may not know this for a number of reasons (they did not install or order the floor, it may be a replacement, and info on the installation has been lost, etc.) Here is an easy way to help out and get the Kilowatt load they need for this menu step.

Kilowatt load usage can be figured by taking the square footage of the open floor space multiplied by 15 (for tile) or 12 (for carpet and laminate). This gives us the total wattage which we then divide by 1000 to get the Kilowatts.

An example: the user has a 100-square-foot room that is tiled. The math would look like this: 100 sq feet X 15 watts per square foot = 1500 divided by 1000 = 1.5 KW

The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

One thermostat can control multiple heating mats/cables as long as all the heating elements are using less than 15 amps:

TempZone™ will cover aprx. 120 sq. ft. for 120V systems and 240 sq. ft. for 240V systems on one thermostat.

Environ™ will cover aprx. 150 sq. ft. for 120V systems and 300 sq. ft. for 240V systems on one thermostat.

Slab Heat will cover aprx. 90 sq. ft. for 120V systems and 180 sq. ft. for 240V systems on one thermostat.

The default is 10k. If this is a new installation, that is the answer. In the very rare occasion that this is replacing an older Energy stat (eg. square OJ Microline from before 2010 with red and green sensor wires), choose 12k. If this is a replacement for the other 99% of the thermostats WarmlyYours sold (Honeywell TH115 and TH111 thermostats), 10k is the value.

Always start with the default 10kΩ and change later if needed.

Pressing and holding (2-3 sec) physical power/reset button will turn the unit completely OFF. Same process turns the unit back on.

(nHance and nJoin units will have the button on the front faceplate, nSpire Touch WiFi, nSpire Touch and nTrust will have the button on the right side of the faceplate.)

Turn the power (circuit breaker typically) to the thermostat off for 5 minutes and then back on to reset the thermostat.

If there is power to the thermostat and it still doesn't appear to work, then the next step toward a solution is to take Ohm measurements of the floor heating system.

This is done with a digital multi-meter that can select a low 200 Ohm (Ω) scale. To conduct this test, turn off the circuit breaker. Remove the thermostat completely from the wall and disconnect the wires connected to the LOAD connections at the back of the thermostat. Disconnect the ground wires from the house ground, and do the test shown on the links below. If you are uncomfortable doing this test, contact a qualified electrician.

Please follow one of these guides based on the type of heating system installed:

TempZone Single Conductor

TempZone Twin Conductor

If the system still does not function, contact +1 (800) 875-5285 WarmlyYours Technical Support and provide the Ohm measurements for further assistance.

Error code "E2" means defective, damaged, or not connected floor sensor. Check connections or replace the sensor if necessary.

Sensor resistance should be in 8kΩ-15kΩ range and can be tested with a digital multimeter on a 20k scale. If the sensor resistance is out of range, it could be damaged. Please note, only one floor sensor can be connected to a single thermostat.

Solution:

Floor load is provided on the installation and electrical plan for your system. Kilowatt load usage can be figured by taking the square footage of the open floor space multiplied by 15 (for tile) or 12 (for carpet and laminate). This gives us the total wattage which we then divide by 1000 to get the Kilowatts. An example. User has a 100 square foot room that is tiled. The math would look like this: 100 sq feet X 15 watts per square foot = 1500 divided by 1000 = 1.5 KW

The ground wire in the floor mat must be connected directly to the ground wire of the supply or to the house ground wire.

The flashing digits indicate that the actual (measured) floor temperature exceeds the thermostat temperature limit.

The temperature limit is set for either tile (104°F/40°C) or laminate (82°F/28°C) when the thermostat is first set up or re-configured.

For example: When the floor type (protection) is set to laminate, the limit defaults to 82°F/28°C. If the floor temperature goes above this - whether due to radiant floor heating or external heating sources, then the digits will flash and the heating is switched off.

Turning the temperature up or down will not affect the flashing digits. And leaving the thermostat alone with flashing digits does not harm the system.

Tip: To turn off the heated floor (ex. for months when it is not needed), on the outer edge of the thermostat, depress the lower right side button for 3-5 seconds. This will also turn it back on.
