Operating Mode
Each fan can operate in one of nine different operating modes:
Cool
– The fan exhausts hot air from the building. The fan turns on when the temperature rises to the ON
temperature and turns off when the building cools to the OFF temperature (if set up to run on temperature).
Heat
– The fan blows hot air into the building from a warmer area. The fan turns on at a low temperature set as the
ON temperature and turns off at a higher temperature set as the OFF temperature.
Purge
– The fan runs during a purge cycle to clear humidity, ammonia, and bad air from the building. The fan runs
based on the purge settings you entered in the Purge Settings menu.
Cool & Purge
– The fan runs in cool mode when the temperature is at or above the fan’s ON temperature and during
purge cycles when the temperature is below the ON temperature.
Heat & Purge
– The fan runs in heat mode when the temperature is below the fan’s ON temperature and during
purge cycles when the temperature is above the ON temperature.
Tunnel
– The fan runs during tunnel mode. Tunnel mode moves air from the tunnel inlets, through the building, and
out through the tunnel fans. It closes all natural sidewall inlets and curtains. Typically, more groups of tunnel fans
turn on as the temperature rises.
Tunnel & Cool
– The fan runs in cool mode when the temperature is below the Tunnel Entry temperature
(refer to the Temperature Control Setting section) and in tunnel mode when the temperature is at or above
fan’s ON temperature.
Tunnel & Purge
– The fan runs during purge cycles when the temperature is below the Tunnel Entry temperature and
in tunnel mode when the temperature is at or above the fan’s ON temperature.
Tunnel, Cool, Purge
– The fan runs during purge cycles when the temperature is below the ON temperature, in cool
mode when the ON temperature is reached, and in tunnel mode when the temperature is at or above the fan’s ON
temperature.

Introduction
This section provides information for fixed-speed fans and variable-speed fans
which have the same functions/screens
available. Any exceptions are appropriately listed.
Menu items specific only to variable speed fans,
in the screen
examples to follow,
have the variable-speed fan symbol next to them.
Use Sensors
Input the group numbers of the air sensors you want to use for controlling the fan group. The controller uses Shared
Sensor Technology to average the temperature readings of any sensors you want to use to control any device.
