FEATURES OF THE SEC-HD
The Staged Environment Control (SEC-HD), is a microprocessor based product designed to efficiently control the
environment in livestock buildings. It connects to two variable speed fans, a combination of secondary fans and heaters and
an alarm system. When operating, the SEC-HD measures and displays the room temperature. While monitoring the
temperature it controls the connected ventilation and heating equipment according to the programmed settings to keep the
temperature at the desired point. The program settings can be adjusted to change the turn on points and other parameters of
the stages. This is a list of the standard features of the SEC-HD.
•Digital display of temperature, alarms and settings
•7 programs with pre-programmed factory settings which can be easily changed
•A built-in keyboard to allow easy adjustment of settings
•3 stages with relay contacts to control secondary fans or heaters
•A relay to signal high or low temperature, power interruptions or low line voltage conditions
•Internal memory is retained during power failures
•115/230 VAC operation @ 10.0 full load amps output for each variable speed fan (with noise suppression to
eliminate radio and T.V. interference)
•Three second full power turn on for variable speed outputs to minimize fan freeze-up
•Transient protected
•Compact design, 18cm/7" (H) x 23cm/9" (W) x 9.5cm/3.75" (D)
•Non-corrosive, fire retardant enclosure
•Two year warranty
•Sensor can be extended
