MinActuatorStep
SW_FilterTimeCon
MinActuatorStep is the minimum possible actuator step. This affects the load controller
accuracy but may stabilize its action. If the value for this parameter is too high, the load
control becomes unstable. The factory setting is 1%.
SW_FilterTimeCon. can be used to delay the internal load controller. If the value for this
parameter is too high, the internal load controller becomes unstable. The factory setting
is 3s.
4.27 Capacity controller on/off
If temperature or pressure has been given a set value, burner start-up and shut
down limits are percentages of the set value. Calculate switching points according to
following example:
Setting
158 °F
Mod_On
Burner start
–10% (=44.6 °F) 158 — 44.6 = 113.4 °F
Mod_Off
Burner shutdown
+5 % (=38.3 °F) 158 + 38.3 = 196.3 °F
Mod_On
is possible to set between
-50…+50 %
Mod_Off
is possible to set between
0…+50 %
