I found system transformer tripped upon arrival. Verified low voltage wiring and reset. System is now communicating as it should. System is also low on r410a.
Arrived to home Checked system Settings good Temp split a little low Noticed discharge and SC fluctuating a little Will contact MFG on Monday
Provided maintenance on equipment and verified good operations. Compressor did have a shutter to its start. System is operating good at this time, suction pressure was a bit high for today’s indoor/outdoor temperatures but has good delta t (air temperature split) and good starting and operating amps. Noticed compressor has potentially experienced reverse rotation, would recommend a sure switch smart contactor with surge protection and short cycling protection to help prevent wear and tear on equipment.
