    Sure...

    and while you're at it, check for air trapped at the individual convectors. Monoflow systems are notorious for being a PITA to get the air out of the convectors. Unless you have auto vents at the tops of all the convectors, you probably still have air in the system. Try bleeding the air with the pumps in the OFF position.

    normally i don't

    recomend or use auto bleeders on a monoflow systems, i use coin vent bleeders. sometimes when bleeding a convector the water will come out hot, but the rest of the convector is cold most likely it's either on a poor pitch or sometimes i've found the handle on the valve at the convector just spins and dosn't turn the shaft on the valve, i would take the handle off the valve, if the flat part of the shaft is facing up the valve is open, remember those are not gate valves they're butterfly valves.
