Hello All,
I have been getting to know my machine and tinkering with the settings and wanted to share some unscientific results from playing with the P6 (P) settings. I was interested in increasing the boiler recovery time (in exchange for increased overshoot). Also I was just using the temp readout on the display of the machine. So again, not super accurate but gives you an idea. Here are the results:

PID P6 Setting Stock (2):
174 to 200= 48sec (overshoot to 201)
176 to 200= 1:00min (no overshoot)
189 to 200= 1:17min (no overshoot)
194 to 200= 1:55min (no overshoot)
194 to 200= 1:58min (no overshoot)
196 to 200= 1:42min (no overshoot)
196 to 200= 2:26min (no overshoot)

PID P6 Setting +1 (3):
171 to 200= 45sec (overshoot to 203)
189 to 200= 59sec (overshoot to 201)
191 to 200= 58sec (no overshoot)
193 to 200= 57sec (no overshoot)
193 to 200= 1:18min (no overshoot)
196 to 200= 1:11min (no overshoot)
196 to 200= 1:10min (no overshoot)

PID P6 Setting +2 (4):
174 to 200= 40sec (overshoot to 205)
184 to 200= 40sec (overshoot to 202)
191 to 200= 52sec (overshoot to 201)
191 to 200= 48sec (overshoot to 201)
192 to 200= 43sec (overshoot to 201)
196 to 200= 52sec (no overshoot)
196 to 200= 46sec (no overshoot)
