Simultaneous Error Codes or faults
There may be cases where multiple errors or faults will be tripped at the same time, or closely follow each other. At this point, the unit will
default operation and limit functionality based on the most severe fault. For example, if there is a slight operational fault but a major fault also
trips, the unit will operate at the safest level that it can during the major fault incident. As an example, the hot water heating might not work in
an Emergency Operation mode due to a more severe fault that prevents it from warming. You might need to check the Domestic Hot Water
(DHW) sensor and related wiring to trace any troubleshooting issues.
If the Hydro Kit is operating in Emergency (Safe) Mode, automatic re-
start is disabled. If there is a loss of power during Emergency Mode; the
unit must be re-started manually. Under normal operating conditions, the
Hydro Kit is designed to automatically start up (reboot) once power is
restored.
Due to our policy of continuous product innovation, some specifications may change without notification.
