Floating reheat
If the controller is configured for floating reheat, it controls two binary triac
outputs to drive the inputs of a tri-state actuator connected to a valve. If the
Reheat loop is less than 30%, the valve is driven closed. If the loop is greater
than 70%, the valve is driven open. If the loop is in between 30% and 70%, no
valve action is taken.
See the topic Floating reheat on page 54 for an application drawing.
