nJoin 2.0 Power Module Description

Some floor heating jobs are just too large for a single radiant heating thermostat to handle alone. The nJoin 2.0 power module is here to help you heat those larger projects. 

The refined and modern-looking nJoin 2.0 links up to current (nJoy and nTrust 2.0) and previous (nSpire Touch WiFi, nSpire Touch, nTrust, and nHance) WarmlyYours radiant heating thermostats to increase the electrical output in 15 amp increments per module. This will help your heating system cover additional areas or large rooms, like basements, with a single thermostat.

The nJoin 2.0 features an attractive update to its design and is equipped with a dual-color LED indicator, offering a straightforward visual display of the unit’s status for effortless monitoring and troubleshooting. The LED changes color to convey different operational messages, ensuring quick and easy diagnostics.

Additionally, because the nJoin 2.0 doesn't provide any direct control functionality, it can be installed out of view if desired.

Comes with two connectors, one for the main thermostat and another for an extra power module if needed, that feature screw terminals for safe and easy installs.

Features: 

  • Works with current (nJoy and  nTrust 2.0) and previous (nSpire Touch WiFi, nSpire Touch, nTrust and nHance) radiant heating thermostats. 
  • 3-year warranty
  • Comes with screw terminals 
  • Built-in self-testing, Class A GFCI
  • Dual voltage: 120V and 240V
  • cULus listed

Please keep in mind that you must check your electric floor heating system with a digital ohmmeter in conjunction with a Circuit Check™. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.

The Circuit Check™ is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.

The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the electric floor heating system.
 The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.

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.

Reflective insulation is not effective with conductive heating, which is how embedded floor heating and snow-melting systems transfer heat. To be effective, the reflective insulation surface needs to face an air space (air gap), which allows the reflected heat to be redirected.

An effective solution considers the insulating material's R-Value. This is the rating of a material's insulating properties. The "R" stands for "resistance" and refers to the material's resistance to heat flow, or temperature conduction.
