B.2 Maximum load on outputs (for hardware 905MN1x_3Rf and up)
Device Max Current Max Power
Control and gas valve 0,5 A 60 VA
All pumps together 1,5 A 180 VA
Fan 2,0 A 240 VA
Total external load 4 A 480 VA
All other devices must be powered externally.
B.3 Minimum/Maximum load on air damper output (J3-6)
The output J3-6 is a triac controlled output. This output needs a minimum load of approx. 10VA to work correctly and the max load must be limited to 50VA
@ supply voltage.
Connection an external relay to this output to be able to switch a higher load is only possible when an additional resistor or load is added to make sure the
minimum load requirements are met.
