Abstract
A water heater appliance may include a casing, a tank, a temperature sensor, a heating system, and a controller. The temperature sensor may be attached to the casing in thermal communication with the tank to detect a temperature thereof. The controller may be in operative communication with the heating system. The controller may be configured to initiate a heating cycle that includes receiving a setpoint request comprising a requested temperature value, detecting a first tank temperature value at the temperature sensor, generating a first modified temperature value less than the first tank temperature value, determining the requested temperature value is less than the first modified temperature value, setting a target setpoint to the first modified temperature value in response to determining the requested temperature value is less than the first modified temperature value, and directing the heating system according to the target setpoint.
