I'm a bit unclear about what you mean by "neither works", but check your Pump Control type. If you set it an "Intermittent", and if there is no load on the loop, it'll shut down. If you want to have run all the time (as minimum flow fraction), use "Continous". Note that this is going to both consume more electricity and impose a heat load on your loop from the inefficiencies of the pump, if your loop has no load for extended periods of time, pump heat build up can occur. In which case, you could use an availability manager to turn off the loop itself.
