Introducing the SEC-HD
The SEC-HD automatically controls the temperature in a room by operating two variable speed fans
and up to three single-speed fans or heaters. To control the temperature, the SEC-HD operates the
connected ventilation and/or heating equipment according to program settings.
Easy to use and program
The SEC-HD comes with seven factory-configured operating programs you can easily reconfigure
for your ideal situation. The easy-to-use keypad and menu system make the SEC-HD one of the
easiest controls to program. The SEC-HD's advanced and powerful features are never more than a
few keystrokes away.
Versatility and peace of mind
The SEC-HD has a 30-foot temperature probe that monitors temperatures and a single zone. For
more versatility, you can connect four temperature probes together and use four-zone averaging.
Temperature probes are available in 1, 6, 30, 75, or 150-foot lengths; you can extend them up to 500
feet using extension cable.
The SEC-HD displays alert conditions such as high and low temperatures, power failure, and low
line voltage, and can also connect to an alarm siren, alarm panel, or auto-dialer. Customizable alarm
settings allow you to choose which alarm conditions you want to be notified about.
Common applications
Livestock applications
Livestock applications include buildings housing calves, rabbits, goats, hogs, poultry, and turkey. In
these applications, the SEC-HD often controls ventilation in a single 20 x 40-foot or smaller room.
However, the SEC-HD is not restricted to small rooms; some customers use it to control ventilation
in sow breeding rooms that are 200 feet long.
