nSpire Touch Programmable Thermostat (White) UDG4-4999-WY

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.

Error code "E2" on a WarmlyYours nSpiration Series Radiant Heating Controls (OJ Microline thermostat) means  there is a defective, damaged, or not connected floor sensor. Check connections or replace the sensor if necessary.

Tbhe floor sensor resistance should be in 8kΩ-15kΩ range and can be tested with a digital multimeter on a 20k scale. If the floor sensor resistance is out of range, it could be damaged. Please note, only one floor sensor can be connected to a single WarmlyYours nSpiration Series Radiant Heating Controls (OJ Microline thermostat).

Cause:

Floor sensor is not connected to terminals C&D, defective or damaged

Solution:

The default is 10k.  If this is a new installation, that is the answer.  In the very rare occasion that this is replacing a 12 year old or older Energy stat (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 other thermostats we sold (Honeywell TH115 and TH111 thermostats), 10 k is the value.

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