nHance Programmable Thermostat

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:

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

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.

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.)

Cause:

Child lock is activated

Solution:

• From the home screen
  
• Press "OK" button twice
• Press button UP and DOWN simultaneously for 3 sec.
• Unlock Child Lock

The key is to get MODE flashing (that's the second time hitting "OK"), and continue to hold (it may take 5 secs) the UP and DOWN buttons simultaneously until the lock disappears.

Cause:

The connection is incorrect

Solution:

Check the connections between the two units. If the USG is connected incorrectly to the thermostat, the USG won't switch off.

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.
