The heat pump is a made for USA product that operates on 1ph 60Hz and with an acceptable voltage range of 210 to 253Vac. I don’t know why they list it as 230Vac, could have listed it as 240Vac. Same thing as loads that are either listed as 115Vac or 120Vac, not much real world difference. With typical utility voltages and with line loss going out to the heat pump actual voltage at the load is more likely closer to 230Vac than to 240Vac. Dave Palumbo

A couple of quick questions. It is a 8 year old OutBack system with two FX2524T’s presently powering two 120Vac legs with no 240Vac output. • Homeowner is adding a Fujitsu mini split heat pump for air conditioning the home (summers are getting hot enough for AC even in northern Vermont). • It uses 7.9 Amps @ 230Vac • I have a OB PSX-240 Autoformer manufactured in 2008 in my inventory here. Should I use it for this application? • Do I wire it up just like in this schematic? • If so, what do I change in the programing on the Mate? Presently it is ADV/FX/STACK stack 1-2ph Master. Do I simply change it to ADV/FX/STACK stack Classic Slave?
