Recirc Return Sensor Lost Error
The control lost communication with the digital recirculation return sensor. The control operates normally
while this error is present. However, if applicable, pump operation may be affected. To correct, check
the wiring. If the wiring and connections are solid, then the sensor may require replacement. Contact
Customer Support for further assistance.
Recirc Return Temperature Error
The control detected an error with the temperature reading from the digital recirculation return sensor.
The control operates normally while this error is present. However, if applicable, pump operation may be
affected. To correct, check the wiring. If the wiring and connections are solid, then the sensor may require
replacement. Contact Customer Support for further assistance.
Recirc Return Pressure Error
The control detected an error with the pressure reading from the digital recirculation return sensor.
The control operates normally while this error is present. However, if applicable, pump operation may be
affected. To correct, check the wiring. If the wiring and connections are solid, then the sensor may require
replacement. Contact Customer Support for further assistance.
Mixed Outlet Flow Error
The control is unable to read flow within the allowable range from the mixed outlet flow sensor. The control
operates normally while this error is present. To correct, check the wiring between the sensor and the control. If
the wiring and connections are solid, then the sensor may require replacement. Contact Customer Support
for further assistance.
Recirc Return Flow Error
The control is unable to read flow within the allowable range from the recirculation return flow sensor.
The control operates normally while this error is present. To correct, check the wiring between the sensor
and the control. If the wiring and connections are solid, then the sensor may require replacement. Contact
Customer Support for further assistance.
Pump 1 Flow Proof Error
The control did not detect a flow proof signal within the delay time after turning on recirculation pump 1.
To correct, check the wiring between the flow proving device and the control. If the wiring and connections
are solid, check the flow proving device and the pump. The flow proving device or pump may require
replacement. Contact Customer Support for further assistance.
Pump 2 Flow Proof Error
The control did not detect a flow proof signal within the delay time after turning on recirculation pump 2.
To correct, check the wiring between the flow proving device and the control. If the wiring and connections
are solid, check the flow proving device and the pump. The flow proving device or the pump may require
replacement. Contact Customer Support for further assistance.
Pump 1 & 2 Flow Proof Error
The control did not detect a flow proof signal within the delay time after turning on the recirculation pumps.
To correct, check the wiring between the flow proving devices and the control. If the wiring and connections
are solid, check the flow proving devices and the pumps. The flow proving device(s) or the pump(s) may
require replacement. Contact Customer Support for further assistance.
