A normal or desirable cholesterol level is defined as less than 200 mg of cholesterol per deciliter of blood (mg/dL). Blood cholesterol is considered to be borderline when it is in the range of 200 to 239 mg/dL. Elevated cholesterol level is 240 mg/dL or above.
Compressor Crankcase Heater. During the normal operation of a central air conditioner or heat pump the compressor is both drawing suction from the evaporator and discharging hot gas into the condenser coil. While running, there is enough heat being generated by the compressor running to keep from creating refrigerant migration from occurring.
When there is a transformer in the cooling system and a second transformer on the heating system then the R wires from each transformer must be kept separated and so they are labeled as Rc (for the R wire from cooling transformer) and Rh (for the R wire from heating transformer).hen the thermostat is set for HEAT (and the fan set to AUTO), neither the blower (G) circuit nor the compressor (Y) circuit are activated, regardless of the thermostat setting.
