If have some questions regarding outputs on my 1611 (upgraded and updated version). I have seen the youtube video's from TA but I feel a bit more safer if I can ask here. I hope you will find time to answer my questions, thank you. In my setup I have 3 Grundfoss Alpha 2 pumps (on off pumps where one pump will be on at "all time" for heater) and 2 Grundfoss Magna 3 pumps (PWN controlled) for solar system using heat exchanger (one on each side). And I need to control my oil burner system (on off) and 2 valves (on off). In total 3+2+1+2 items to be controlled in on-off. The Alpha 2 pumps are going to be used as on-off pumps depending on the appropriate function - setting on pumps will be auto adapt on low or mid level. For the alpha 2 pumps my questions are: 1) what output port are to be used? I do not need speed adjustable for Alpha 2, so I only need on-off setting (I think I have read that low consumption pumps as Alpha 2 might give some problems direct on output port). I prefer to isolate 1611 and pumps by external relay - so 1611 output will control a relay that deliver voltage to the pump (for Alpha 2 pumps can I thus use A3, A4 and A5-pot free?) 2) For electrical valves (on off) - can I direct use A8 and A9? 3) For the 2 Magna 3 pumps - they are now not low energy consumption items, so is it A10 and A11 or Hirel 1, 2 (A12 and A13). 4) Finally - my oil burner: I do not know power consumption so I definitely need external relay for security - could this be port A2 with external relay? 5) When reading "UVR1611 version A4.03 EN - freely programmable universal controller") I can not see maximum power consumption on each output ports and maximum in total for all output ports. (I want to test the outputs through display on 1611 before designing in TAPPS). Thank you.

If have some questions regarding outputs on my 1611 (upgraded and updated version). I have seen the youtube video's from TA but I feel a bit more safer if I can ask here. I hope you will find time to answer my questions, thank you. In my setup I have 3 Grundfoss Alpha 2 pumps (on off pumps where one pump will be on at "all time" for heater) and 2 Grundfoss Magna 3 pumps (PWN controlled) for solar system using heat exchanger (one on each side).
MAGNA pumps: These pumps will have two connections:
1) The mains connection (does NOT have to go through the UVR, but you can do it, if you have enough output ports available AND you want to be able to cut the power to the pump entirely)
2) The PWM output (from the UVR1611 or similar device)
For the UVR1611, output 15 and 16 can be used as PWM. It is an "analogue output". PWM is just a small AC control signal, which you can vary from 0-100. The signal itself is only around 10V.
And I need to control my oil burner system (on off) and 2 valves (on off). In total 3+2+1+2 items to be controlled in on-off.
Motor valves usually only use 1-3W, depending on which type they are. They aren't critical at all.
The Alpha 2 pumps are going to be used as on-off pumps depending on the appropriate function - setting on pumps will be auto adapt on low or mid level. For the alpha 2 pumps my questions are: 1) what output port are to be used? I do not need speed adjustable for Alpha 2, so I only need on-off setting (I think I have read that low consumption pumps as Alpha 2 might give some problems direct on output port).
I prefer to isolate 1611 and pumps by external relay - so 1611 output will control a relay that deliver voltage to the pump (for Alpha 2 pumps can I thus use A3, A4 and A5-pot free?)
2) For electrical valves (on off) - can I direct use A8 and A9?
3) For the 2 Magna 3 pumps - they are now not low energy consumption items, so is it A10 and A11 or Hirel 1, 2 (A12 and A13).
AUTO - via the program, 0-100% being asked via PWM
ON - Running manually (and then there is one more parameter, where you determine what the on default value is
OFF - always off
MAN - now the second value can be user selected, 0-100% (a bit similar to the ON function, but ON is determined in the program, while MAN can be determined by direct user input)
4) Finally - my oil burner: I do not know power consumption so I definitely need external relay for security - could this be port A2 with external relay?
5) When reading "UVR1611 version A4.03 EN - freely programmable universal controller") I can not see maximum power consumption on each output ports and maximum in total for all output ports. (I want to test the outputs through display on 1611 before designing in TAPPS). Thank you.
Sorry about the delay, and hope it answers your questions!

About controlling a gas or oil boiler (furnace), this is an example from a Vaillant Thermocompact boiler:
In this boiler, #3 and #4 on the terminal strip is normally connected with a small cable. This installation I did, the gas boiler is then connected to an RSM610 (similar port as on the UVR1611), so if the port is closed, the furnace is demanded to run (Danish: "Brænderkald"). Note that you should NOT run mains power into the this boiler port #3 and #4. If you did, you COULD be lucky to match the phase and ground, but most likely, it would cause a spark and a costly repair. Hence, you need to use that "potential-free" output port 5 on the UVR1611, and set it correctly in the programming. I will need to check but also think you need some plug (Danish: "Lus") on the 1611 circuit board. Look up the details in the manual, for output port 5.
Again, this is from the Vaillant boiler:
