On HotKey-equipped controllers, the output channel labels are also hot keys. Pressing
a channel label key will take you directly to the operating parameters menus for the
related device.
Introduction:
You must designate how curtains and inlets will operate. Ridge vents are natural only. There are four basic operating
modes:
•
Natural
- Operates for all ventilation below the Tunnel Entry Temperature. Often referred to as power, minimum,
or natural ventilation. Natural curtains and inlets are closed during tunnel mode.
•
Tunnel
- Operates only during tunnel mode. Tunnel curtains and inlets are closed during natural mode.
•
Static
- Operates automatically based on the static pressure sensor readings. Static pressure control menus are
displayed only when a static pressure sensor is installed. Static-pressure-controlled devices open or close based on
the Open and Close values entered in the Static Pressure Setting menu.
•
Temp
- Operates based on temperature (typically curtains) or operates proportionally (typically inlets) based on
the number of fans running.
The above modes are combined for the following menu choices.
•
Static Tunnel Only
- The device only operates during tunnel mode and is controlled by static pressure.
•
Temp Natural Only
- The device only operates during natural mode. An inlet opens or closes based on the number
of fan groups running (proportional control). A curtain opens or closes based on its Open Temp and Close Temp.
•
Static Natural Only
- The device only operates during natural mode and is controlled by static pressure.
•
Temp Natural/Temp Tunnel
- During natural mode, an inlet operates based on the number of fan groups running
(proportional control). A curtain operates based on its Open Temp and Close Temp settings. During tunnel mode,
the inlet or curtain operates based on proportional control.
•
Temp Natural/Static Tunnel
- During natural mode, an inlet operates based on the number of fan groups running
(proportional control). A curtain operates based on its Open Temp and Close Temp settings. During tunnel mode,
the inlet or curtain operates based on static pressure.
•
Temp Tunnel Only
- The inlet or curtain operates only during tunnel mode and its position is based on the number
of fan groups running (proportional control).
•
Static Natural/Temp Tunnel
- During natural mode, the device operates based on static pressure. During tunnel
mode, the device operates based on proportional control.
•
Static Natural/Static Tunnel
- The device operates based on static pressure during natural mode and tunnel mode.
See Appendix 2, page 164 for a summary of how inlets/curtains behave in each mode.
Setting up Output Devices
This controller uses Shared Sensor Technology to control all the devices in the building. Any combination of sensors
can be averaged to control any device. You may assign up to four sensors to each equipment group. Enter four zeros
to assign all indoor temperature sensors to a group.
To change sensor numbers while you are setting up operating parameters for an output device (operating
parameters are discussed later in this manual).
You may use Channel Hot-Keys next to each toggle switch on the main
control for accessing the menu item for that channel’s device. Expansion stations do not have Hot-Keys.
1. Press ENTER while you are viewing a menu item where sensors can be selected (usually displays Use Sensors).
2. Press the PLUS or MINUS keys to input the sensor number you want to have control the equipment group.
3. Press ENTER to confirm.
4. Repeat steps 2-3 for each sensor.
5. If the cursor is still present, press ENTER until it disappears.
6. The average temperature of all controlling sensors is listed at the right.
