b. General Information. To increase comfort and save energy:

(1) During warm or cold weather. Air conditioner in COOL or HEAT modes:

(a) Limit traffic through doors as much as possible.

(b) Keep doors and windows tightly closed.

NOTE

It is normally better to keep the fresh air damper slightly open. This will create a

slight overpressure, provide replacement oxygen, and reduce room odors.

Damper should be closed during extreme weather conditions and during periods

when fast warm up or cooling is necessary.

(d) Do not adjust controls unnecessarily. Properly set the controls and the unit will automatically control

the temperature.

(e) The TEMPerature control thermostat on the control panel operates like a conventional room

thermostat except that the temperature scale is not marked on the control panel. The thermostat has a control range of

40F to 90F (5C to 32C). The centered position of the control knob would be approximately 65F (18 C). The full

INCREASE would be 90F (32 C). The full DECREASE would be 40 F (5C).

(f) With the control panel mounted in the unit the control temperature is sensed at the conditioned air

inlet.

(2) During cold weather.

(a) Adjust shades, blinds, etc., when applicable, to admit sunlight during the day. Close them at night.

(b) Adjust the conditioned air outlet dampers slightly downward.

(3) During hot weather.

(a) Adjust shades, blinds, etc., when applicable, to block out sunlight during the day.

(b) Adjust the conditioned air outlet dampers slightly upward.
