relays and fan motors. Applications include two-
pipe and four-pipe fan coil units, air handling units,
and heating and cooling applications.
Features:
• Manual or automatic changeover models.
• Line voltage 3-speed fan control.
• Continuous or cycling fan operation (cycling fan operation
requires additional relay or relays).
• Handles all supply voltages from 24 to 277 Vac at
50/60 Hz (fan and system voltage must be the same).
