11.5 Sensor 2 menu, secondary inlet temperature sensor
When the temperature measured with S1 and S2 suddenly increases or decreases, this function will send an
action signal to the control valve and the primary pump.
The Delta T (S1-S2) function is only valid for variable charging pumps.
When the S2 temperature approaches S1 temperature, an auxiliary control loop reduces charging pump speed
down to a minimum of settable value (see below), at the opposite, if the temperature on S2 decreases, the
pump speed increases.
