I've come across a similar situation trying to only allow flow in a radiant panel for specific temperature ranges. What I found is that if I replaced my AvailabilityManager:HighTemperatureTurnOff objects (which turn plant loops OFF when a sensor node is ABOVE a specific temperature) to AvailabilityManager:LowTemperatureTurnOn objects (which turn plant loops ON when a sensor node is BELOW a specific temperature), then it operated as desired.
In general, each System Availability Manager object in E+ has a "Control Status" output variable. The values indicate whether the Availability Manager is telling the Plant loop to 'Force Off', 'Cycle On', or 'No Action'. Precedence for controlling the loop also follows that order: if ANY component on the plant loop has an availability manager that reports 'Force Off', then the entire plant loop will be forced off.
