(Redirected from LBBB). Left bundle branch block (LBBB) is a cardiac conduction abnormality seen on the electrocardiogram (ECG). In this condition, activation of the left ventricle is delayed, which causes the left ventricle to contract later than the right ventricle.
For instance, in the winter, if you set the thermostat to 20Â°C (68Â°F), it will activate the heating system when the house temperature drops below 20Â°C and will shut the system off when the house air warms up past 20Â°C. A setback thermostat contains an electronic clock.
Set your water heater's thermostat to 150 degrees Fahrenheit to prevent scalding. If you have no dishwasher running in your house, you can set the temperature even lower. To cut down on energy usage, insulate your water heater's pipes, especially if they must run a long way to reach your unit.
