@@tony-of7pi upo sir same lng po communication error.

@@randelbaldove8996 thank you sir

Thanks 😁

turn off your power supply for 5 mins and power on again and wait for compressor running and check the voltage if dropping,,its low voltage protection.

@@randelbaldove8996 Thanks it worked.

H4 is appeared when L0/ L1 triggering 3 times L1 means low voltage first check your Voltage is dropping when the compressor is running if in stable Voltage,manually turning off you circuit breaker and wait 5mins power on again.thanks

@@randelbaldove8996 I did exactly that just pull the fuses and wait now it works thanks!

@@franckdanielbandolo894 menu sitting n41 to n48 you can select what you want for pressure..

Thanks for watching..If one outdoor unit only you set ENC3 for how many indoors qauntity connected.. for example you have 12 indoors you select C means 12.

You can go to menu sitting, check dry contact function nc(1)02

If there is problem you cannot go until stp7 to finish start up.

@@veter_kg yes its work.

Only centralized controller can activate the lock function of this thermostat model.

Check your compressor if working

Call service center for service.

Ok lng sir,kahit dto po kayo magmessage.

@@randelbaldove8996 May iiinstall kasi ako AHU-50tr connected to 3 ACCU vc pro. meron po ba kau maireccommend na installer

If not responding removed the power cable and plug in again to make reseting again.

Pwedi po sir pag na check nyo yung parameters reading normal yung pressure pwedi nyo muna lagyan ng jumper for emergency, dapat palitan nyo rin ng bagong h/p for safety.

@@randelbaldove8996 panu maglagay ng jumper sa gantong nakasalpak sa mismong main board na high-pressure switch?

Yes sir you are 90%right almost same case lack of refrigerant,but we find the problem is clogging the orefice cause of high ampere and compressor stop..thanks

@@randelbaldove8996 Yes, I made the comment before watching the vide just based upon the title which is why I put the word "usually" first and yes not only high current but also the high side pressure should have been going through the roof and shut down the compressor if it has a high pressure cutoff switch. That still leaves two questions... Where did the particulates come from to clog the fixed orifice? Maybe compressor or flakes from the inside of the tubes? Second question: Why didn't they make it with a filter dryer? I didn't see if you installed one post orifice replacement. Thanks.

My video not completely because of my cellphone is dead thats why viewer not see we replace the orifice...thanks
