[TRNSYS-users] Exact same control signal for different Type 11f gives diferent results.

[Javier Vega via TRNSYS-users]

Hello TRNSYS users,

I want to use two Type 11f (controller flow diverter) components with the
same control signal. One Type 11f redirects solar collector flow
(Type 553), while the other redirects another circuit's flow to one an
Air-Source Heat Pump or a Water Source Heat Pump  (Type 941 or Type 927).
The  events are supposed to happen at the same time.

Monitoring the results, my DHW temperature falls. When I looked it up, the
flow diverters aren't working at the same time. And what it's worse,
something happens with the Heat Pumps: I studied the control signals, and
they are activated at the same time, but the heat pump's circuit redirects
the flow when it isn't supposed to happen and also the Heat Pump that by
mistakes recieves flow doesn't heat the water flow. This is what bothers me
the most because I set the Heating control signal to a constant 1, so
everytime the HP recieves flow it heats.

I simply don't know how to address this issue, same control signals giving
different results, and a Heat Pump that recieves flow by mistake but
doesn't heat. I would appreciate some help.

Kind Regards,
