    Why is the water from my IBC 30 Water Heater too hot?
    • A

      If the water at your faucets is too hot when using an IBC Water Heater, the boiler's DHW temperature setting might be too high. Try reducing the DHW Tank Set Point temperature in the Configure Load Menu. Alternatively, the DHW temperature sensor may be giving a false reading to the IBC Control, perhaps because the sensor has fallen from its well, is giving an incorrect resistance reading, is improperly connected to the Therm terminals instead of the DHW S terminals, or an improper 3rd party sensor is installed in well.

      If the water at your faucets is too cool when using an IBC Water Heater, it could be due to a low DHW temperature setting on the IBC boiler. You can try to increase the DHW Tank Set Point temperature in the Configure Load Menu. Also, the IBC boiler DHW Maximum Supply Temp setting might be too low. Ensure the Maximum Supply Temp setting is at least 10°F higher than the DHW Supply Setpoint plus 1/2 of the Supply Diff’l Temp setting.
