Key Features of Two-Speed Fan Thermostats for Industrial and Commercial Use
Tempro’s thermostats come with steel or stainless-steel NEMA 1 or NEMA 4X rated enclosures, offering protection from dust, light splashes, daily wear or wash down environements. You can choose between fixed bulb and remote bulb sensors.
How Tempro’s Two-Stage Line Voltage Thermostats for Cooling Control Airflow
SPDT/SPDT Switching Mechanism: The thermostat uses dual SPDT switches to control both a damper motor and a fan motor in a two-speed fan setup. When the temperature reaches the knob setting, the damper motor is energized. If the temperature continues to rise by about 3°F, the high-temperature switch activates the fan motor, increasing airflow to help maintain optimal conditions.
Figure 5 to the right in the user manual shows a typical SPDT/SPDT connection for a two-speed fan application. It illustrates how the damper motor and fan motor are wired and operate as temperature conditions change.
