Product data

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. Wired control to enter set points and operating conditions.
4. Filter status indication after 250 hours of indoor fan operation.
5. Automatic airsweep control to provide on or off activation of airsweep louvers.
6. Cooling mode to provide modulating fan speed based on difference between
temperature setpoint and space temperature.
7. Fan only operation to provide room air circulation when no cooling is required.
8. A 50-ft indoor to outdoor control connection cable shall be provided with the fan
coil unit.
9. Fan speed control shall be user-selectable: high, medium, low, or automatic
operation during all operating modes.
