Fan Coil thermostat wiring

I lived in an apartment in Canada installed with Polar Air High Wall Fan Coil unit(2 pipes) SWC-12-VYW-AECM.  Unfortunately, I need to replace my 24V Polar Air Thermostats which is now no longer available. I found a 24V fancoil thermostat(2 Pipes) from Aliexpress China, I was able to match wiring from the old thermostat to the new one R(9), C(8), G2(7), G1(6), G0(5).  Not sure about where W1O & Y1O should go as the new thermostat has two connection point named Valve Open(4) & Value Close(3).  Should W1O & Y1O both go into (4)Valve Open?
