Heating/Cooling Stage (A/B) "Boost"
The second stage is used to control a second heating or
cooling source that allows the "boost" function.
The "boost"
function enables the second auxiliary source when the
current temperature differs from the current setpoint by more
than the set threshold.
In this way, the main heating/cooling stage is assisted by the
auxiliary source to reach the desired setpoint value faster.
This feature is particularly useful for improving comfort in
dynamic lens systems such as underfloor systems.
