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

Frequently Asked Questions

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.
No, floor heating thermostats are not compatible with the towel warmers. We would also not recommend using both devices on the same control, as it does not take the same amount of time to reach the ideal temperature for each product, which could lead to one unit to overheat and the other to not function properly.
