Fault Code E07
This display indicates that one or both of the clip-on temperature sensors in the hydronic heating module
has been disconnected. This error allows the tank portion of the unit to still operate, but will not allow the
hydronic heating module to operate until the error is cleared. The error will clear if proper sensor
connection is restored. The second line indicates the status of the pump.
Remedy:
1. Go to the STATUS menu screen that displays “CH Supply” on the bottom line. This will help to
determine which sensor has the error. If the temperature displayed is a reasonable number, the error will
be in the return temperature sensor (Horizontal Pipe). If the temperature displayed is not reasonable, the
error will be in the supply sensor (Vertical Pipe).
2. Check the electrical connection to the thermistor on the outlet manifold. Check the wiring harness. If
both are connected properly, replace the control. NOTE: Verify the themistor values by referencing the
Resistance Tables in Section 12.
3. Replace themistor if necessary.
Fault Code ECS NOT CONNECTED
This display indicates that the main control board and the smaller ECS control board are not com-
municating properly. This error allows the tank portion of the unit to still operate, but will not allow the
hydronic heating module to operate until the error is cleared. The second line indicates the status of the
pump.
Remedy:
1. Check to make sure both ends of the ribbon cable are connected properly and securely in place.
2. If both ends have a proper connection, check the ribbon cable for damage or wear. If any problems are
found, replace the ribbon cable.
3. If problem still occurs with the new ribbon cable, replace the ECS board.
Fault Code TEMPER BLOCKING
This display indicates a temporary hold on the burner ignition. This situation occurs when the top tank
sensor is above the set point and the bottom of the tank is substantially cooler than the top. This is a
temporary hold on the burner only and all other functions will remain functioning properly. This error will
clear itself when either the top tank temperature drops below the set point or the bottom temperature
rises.
