Let the system thermostat run until the temperature is at the highest level and the indicator light goes out. Use an accurate thermometer to measure the water temperature should be at 40 ° C (104 ° F). However, the temperature control device may have an error, and the temperature you measure may be slightly Above or below the pre-set level of 40 ° C (140 ° F). If the deviation exceeds ± 3 ° C (± 5 ° F) or more, contact your dealer for corrective action.
