Graph 2 5 Step Modulation
Graph 3 Fixed Power Regulation
Tuning the PID modulation:
-
If your boiler never reaches the setpoint, Increase the Mod1 Power level.
-
If your boiler exceeds the setpoint more than the hysteresis value, Decrease the Mod1
Power Level.
-
If your heating circuit(s) power demand is too low for the boiler (for example only utility
water heating in summer) you may decrease the Mod5 Power level to avoid overshoot
the temperature setpoint.
