Antifreeze Protection and Temperature Settings
Furrion’s tankless water heater incorporates an integrated antifreeze protection system that automatically shuts off the burner when the incoming water temperature drops below a user‑defined threshold. The system monitors the inlet temperature via a thermistor and, if the reading falls below 32 °F, it triggers a safety cutoff to prevent freezing of the internal heat exchanger. Users can adjust the cutoff point in 5 °F increments between 20 °F and 45 °F using the control panel’s “Freeze‑Protect” menu. This flexibility allows RV owners to tailor the protection to local climate conditions while ensuring the unit remains operational during mild winter nights.
The temperature settings for the hot water output are also user‑configurable. The thermostat allows a range from 120 °F to 140 °F, with 5 °F increments. The default setting is 120 °F, which balances comfort and energy efficiency. When the thermostat reaches the setpoint, the burner cycles on and off to maintain the desired temperature. The control panel displays both the inlet and outlet temperatures, and a “Boost” function can temporarily raise the output temperature by 10 °F for a short period, useful for quick showers or rinsing dishes. It is recommended to keep the output temperature below 125 °F in areas with high ambient temperatures to avoid scalding hazards. The heater’s safety interlocks also monitor the pressure and flow rate; if either falls outside the acceptable range, the unit will shut down and display an error code on the LCD. Regular calibration of the thermistor and verification of the temperature sensor’s accuracy are part of the annual maintenance routine.
