(This alarm only displays
if Supply Diagnostics is
enabled in the Smatrix

The supply temperature is too low.
• Check the heat source or supply temperature

• Other potential causes may be too low flow on
the supply line or a malfunctioning circulation

Thermostat setpoints are too low.
• Increase the setpoints on the thermostats in
the rooms where the average temperature is
calculated.
The supply temperature is too low.
