This alert will indicate that the water temperature passing through the cell has increased by more than 10ºC within a two minute period. The system will stop the pump and go into a cycle mode for approximately 20 minutes to test and retest the water temperature. Once completed the system will start the pump and check the temperature again if the temperature is then consistent the unit will go back to normal operation.
This feature is designed to protect your equipment in the event of a possible closed valve or water flow fault where the temperature can cause irreversible damage.
A common cause for this alert is gas heaters causing the water temperature to increase extremely fast. If this is the case please contact us to make adjustments so this does not occur in the future.
