VTC-1D user manual
The Variable Temperature Control (VTC-1D) automatically controls the temperature in a room by adjusting
the speed of variable speed fans.
When the temperature is at the temperature set point, the VTC-1D operates the fans at the idle speed setting.
When the temperature exceeds the set point, the VTC-1D increases the speed. When the temperature drops
below the set point, the VTC-1D shuts off the fans (in shut-off mode) or operates the fans at idle speed (idle
mode).

Electrical ratings
Input:
115/230 VAC, 50/60 Hz
Variable stage: 10 A at 120/230 VAC, general-purpose (resistive)
7 FLA at 120/230 VAC, PSC motor
1/2 HP at 120 VAC, 1 HP at 230 VAC, PSC motor
Fuse:
15 A, 250 VAC ABC-type ceramic
The FLA (full load ampere) rating accounts for the increase in motor current draw
when the motor operates at less than full speed. Make sure the motor/equipment
connected to the variable stage does not draw more than 7 FLA.
