Product data

Note: The units use the AccuRater piston refrigerant metering device in the indoor
unit (for cooling) and at the outdoor unit liquid line service valve for heating.
E. Motors:
Motors shall be permanently lubricated ball bearing with inherent overload
protection. Fan motors shall be 3-speed.
F. Controls:
Controls shall consist of a solid-state electromechanical control system which shall
control space temperature, determine optimum fan speed. The temperature control
range shall be from 64 F to 84 F. The unit shall have the following functions as a
minimum.
1. An automatic restart after power failure at the same operating conditions as at
failure.
2. Non-programmable thermostat to provide cooling and heating set points and
day/nigh setback modes.
3. Evaporator coil freeze protection.
4. Wired control to enter set points and operating conditions.
5. Filter status indication after 250 hours of indoor fan operation.
6. Automatic airsweep control to provide on or off activation of airsweep
louvers.
7. Cooling mode to provide modulating fan speed based on difference between
temperature setpoint and space temperature.
8. Fan only operation to provide room air circulation when no cooling is
required.
9. A 50-ft indoor to outdoor control connection cable shall be provided with the
fan coil unit.
10. Fan speed control shall be user-selectable: high, medium, low, or automatic
operation during all operating modes.
11. A time delay shall prevent compressor restart in less than 2 or 4 minutes
(adjustable).
12. Automatic heating-to-cooling changeover to provide automatic heating and
cooling operation. Control shall include deadband to prevent rapid mode
cycling.
G. Filters:
Unit shall have filter track with factory-supplied cleanable filters.
H. Electrical Requirements:
