Installation Manuel

How It Works:

When this occurs, the NXM2G will hold off the boiler firing (save mode) based on temperature and time,which are both adaptive. This control function will also inhibit the burner from firing on high fire if the boilerload demand is low, thus ensuring the best efficiency for the current system demand. This eliminates the wastedenergy caused by standby cycling

Value Delivered:

The NXM2G measures the supply and return temperature via digital sensors and monitors the “call for heat”.      
​ • On first firing, the boiler will reach the normal thermostat set 
​ point and turn off.  
  • On the next stage, the NXM2G will check:
​  1. For the “call for heat”     
2. If the boiler supply and return temperatures are within the designed
temperature differential settings, and
​ 3. If the boiler is required to fire, based on control algorithms.
Intelligent Boiler Load Optimizer
The NXM2G system is an intelligent micro -processor based boiler load optimization control system designed to REDUCE ENERGY COSTS by providing optimum thermal efficiency of Low Temperature Hot Water (LTHW) boilers.
