My reasons for thinking he may have a servo or linkage issue is the heavy load on the one pack and the heating on the Fromeco unit. The big draw on the one pack seems just too high. In normal use, the Fromeco controller should never be hot, in fact it shouldn&rsquo;t even be hardly warm.</p>

My guess is the voltage output on the Fromeco is below the Digiswitch and is not being drawn from little if any.</p>

The OP really needs to give us ma put back in not percentage.</p></span>
