If the Symmons Control Unit experiences a cold to hot or hot to cold bypass, it's likely that the checks are not seating properly. Try cleaning any fouled checks. If they are damaged, replace the damaged parts.
Why does the temperature drop when using Symmons 7-700?
If the temperature of your Symmons Control Unit drops during draw (when sinks or showers are running), it might be because the valve was set in no draw mode. To fix this, run the showers and sinks, and then set the valve.
Why is the Symmons 7-700 temperature too low?
If the hot water temperature at your sink or shower is below the set point of the Symmons TempControl, it could be due to insufficient circulation of tempered water reaching the hot water source. To resolve this, consider re-piping the system according to diagram 2 or 3 (pg. 9), which allows the discharge of the pump (tempered water return) to go back to the hot water source and the cold inlet of the TempControl.
Why is Symmons 7-700 overheating when not in use?
If the thermometer in the Symmons TempControl outlet rises to the temperature of the heater when there's no draw (i.e., no sinks or showers running), it indicates that there is no circulation of tempered water because the return line is piped to the hot water source only. To fix this, re-pipe the system to diagram 2 or 3 (pg. 9), which allows the discharge of the pump (tempered water return) to go back to the hot water source and the cold inlet of the TempControl.
What to do if I cannot adjust the temperature on my Symmons 7-700?
If you cannot elevate or decrease tempered water by turning the adjustment bolt on your Symmons Control Unit, the piston may be stuck with foreign matter. Remove the cartridge and soak it in household vinegar for an hour. If the piston does not free after soaking, replace the cartridge.
Why does the temperature keep rising in Symmons 7-700 Control Unit?
If the temperature of your Symmons Control Unit rises unexpectedly, it could be because it's not piped according to Diagrams 2 or 3, or the ball valve is too far open. Ensure a check valve is installed on the cold supply to the controller, or adjust the ball valve as shown in diagram 2 or 3 on page 9.
