Magnum MSH3012M Hi I am trying to get my Magnum inverter charger to do load support for running my 15000btu air conditioner which is equipped with a soft start box. Of my Honda EU2200i. I have 300A lithium batteries and can run the air conditioner of the inverter ok but opviesly not for any length of time, so connects the generator and it will charge the batteries at about 100A but as soon as I try to start air conditioner the generator drops out. Is it possible to do, or is generator to small? any help appreciated. Frank Ottosen. Atwood hydro flame model 2H2C Two stage Furnace Digital Thermostat Last year I removed my furnace as it didn’t work and installed a diesel heater instead. I now find that my thermostat is blank and will not run air conditioner. Apparently there is a connection with the furnace that turns on the thermostat. There is a 6 pin plug that attaches to furnace it has only 4 pins used, White wire 12VDC which also is number 1 from left on thermostat. Nr 2 not connected on thermostat. 3 on thermostat is red wire +12VDC. 4 is black on thermostat Relay Com. 5 is green AC compressor also at plug to furnace. 6 AC hi fan blue and also at Plug to furnace. 7 is low fan Orange on thermostat. 8TH on thermostat black TH from furnace. Any( bright sparks) that can tell me how to possible jumper or attach wires so as to power up thermostat. thanks Frank.
