If you are configuring an output signal to a reversing valve , you must use
HeatCoolx as the output stage for the compressor. In all other cases, use Heatx
and Coolx as output stages for the compressor. If you are configuring an output
signal to a 2-pipe fan coil , you must use HeatCoolx as the output stage.
2. In the Control Type field, select the method of control used on the output device signal.
The control types available in the drop-down list changes depending on the option selected
in the Function field as well as the physical output used to connect to the output device. For
more information about control types, see the Control Types topic .
3. In the Action field, choose between direct or reverse control.
4. If you selected a tri-state valve in the Control Type field, in the additional settings,
l
OP1-2Runtime. Allows you to enter in seconds how long the floating valve actuator to
stroke from one end point to the other. This allows the algorithm to estimate the valve
position by keeping track of how many seconds it runs in each direction.
5. Complete this task by setting up a fan output .
