Any residential heating system is the reverse of a cooling system. Family living habits that help the heating system hurt the cooling system. The heat pump, furnace, or boilerdelivers heat into the rooms and the heat that is created within the house from electric lights, cooking, the TV set, etc. helps to heat the rooms - therefore, that much less heat is required from the b_lsr, furnace, or heat pump.
Cooling is just the reverse. The cooling equip-
ment removes heat and humidity. Any extra heat released into the rooms from these same
sources will make the room air warmer and place an extra burden upon the equipment.
Let's take the heat caused by cooking. For example, four top burners of a gas range can produce more heat than a three horsepower air conditioner can remove. It is much more prac- tical and economical to ventilate this concen- trate heat and moisture load than it is to dispose
of it through your air conditioner. Here is a general rule.
Whenever you plan to have your oven or range top burners on for more than a few minutes during hot weather, close off the kitchen from the rest of the house, open a window or outside door, and turn on your kitchen ventilator.
You can also effectively reduce the load on your cooling system by keeping window shades, blinds, or drapes closed or by installing awnings or canopies.
There are days when the temperature is rela- tively high, yet it is comfortable because the air is dry. This is because the relative humidity is
low. There are other days when the tempera- ture is about the same but there is discomfort.
This is because the humidity is high.
Indoors, the air should be both cool and rela- tively dry for comfort. Therefore," the cooling
unit has been designed to remove both heat and moisture.
THERMOSTAT SETTING
For cooling, a temperature of 75 to 78 degrees is preferred by most people. You may select lower temperature setting if you wish and you will probably have that temperature a good portion of the time. But do not be disappointed and condemn the equipment if the temperature gets a few degrees war_e_during hot weather. Set the thermostat at the temperature agree- able to the family and leave it there.
Do not be concerned if, in the evening, when the outside temperature drops below the inside temperature, your air conditioning system is still running. The entire structure of your house has been soaking up heat from the sun all day long.
After the sun has set there is still a tremendous amount of heat in the walls, ceiling, roof, fur- nishings, etc., that must be disposed of before the air conditioner stops running. Outdoor temperatures can drop rapidly after sundown, while the house and its furnishings continue to give off heat for several hours.
Indoor Blower and Outdoor Fan Operation: To improve the efficiency of the unit, the blower is operated on a time delay. Depending on the outside ambient, the blower could delay starting up for 5 to 15 seconds even though the thermostat calls for cooling or heating and when the thermostat is satisfied, the blower could. keep on running for 1/2 to I 1/2 minutes longer. Do not be alarmed if you do not hear the blower running immediately after the unit switches on. When you unit is being automatically defrosted, the outdoor fan will stop while the unit is still running. Do not be concerned, this is a normal operation. The fan will automatically restart after the unit has completed its defrost cycle. After a defrost cycle, you may find condensate dripping from the unit on to the pad or roof. This is normal.
Your unitis a Heat Pump. It is producing heated" air on the heating cycle and cooled air on the cooling cycle. The cooling or heating is accomplished by means of remote controls, is completelyautomatic, and requires no attention after setting to the comfort level you desire.
