Short time delay to preventnuisance starts due to momentary temperature and modulation rate swings.Water heater Off DelayTime Delay after the Off Point setpoint before stopping the next water heater. Short time delay toprevent nuisance stops due to momentary temperature and modulation rate swings.High Fire LimitHigh modulation rate limit for all water heaters on the peer-to-peer network as long as at least onewater heater is still not running. After the last water heater has started the modulation rate is releasedup to 100%.RotationSpecifies number of hours (cumulative) a lead water heater runs before passing the lead to anotherwater heater.Lead rote will be surrendered earlier if the lead water heater is placed into manual mode, is runningremotely (mode 6), fails to start, is “blind” (all input sensors failed), or is satisfying a DHWP request.Rotate AfterSpecifies number of hours (cumulative) a lead water heater runs before passing the lead to anotherwater heater.Outdoor SensorEnables the Outside Air Temperature sensor and display and control logic:Outside Air Input (O+O-) is ignored.Do Not Calculate setpoint based on outdoor temperature, Display Outside Air TemperatureCalculate the temperature setpoint based on outdoor temperature using a reset curve defined byOutdoor Set Up, Water heater Set Up, Outdoor Design and water heater Design parameters.Outdoor Set UpThe Outdoor Set Up temperature is the outdoor temperature at which the Water heater Set Up temperatureis supplied. Only visible when Outdoor Sensor is set to Outdoor Reset.Water heater Set UpThe Water heater Set Up temperature is the starting water heater water temperature of the resetratio. If the building feels cool during mild outdoor conditions, the Water heater Set Up setting shouldbe increased. Only visible when Outdoor Sensor is set to Outdoor Reset.Outdoor DesignThe Outdoor Design temperature is the outdoor temperature at which the Water heater Design temperatureis supplied.Only visible when Outdoor Sensor is set to Outdoor ResetWater heater DesignThe Water heater Design setting is the water temperature required to satisfy the building heat lossduring the Outdoor Design temperature. If the building feels cool during cold outside conditions, theWater heater Design setting should be increased.Only visible when Outdoor Sensor is set to Outdoor Reset.52
