The GTK15 recirculation pump timer is not compatible with SENSEI™ Tankless Water Heaters.

When a GTK15 recirculation pump is used with a SENSEI™ Tankless Water Heater, the integrated timer on the pump is not compatible with the tankless water heater. SENSEI™ Tankless Water Heaters include a diagnostic feature that monitors the recirculation flow rate. If recirculation flow is low or not detected, the tankless water heater will display diagnostic code 63. While code 63 is displayed, hot water will remain available from the tankless water heater but the recirculation pump will be disabled until the source of the diagnostic code is identified and resolved.
