I did replaced yung mga units na erratic yung pag on ng compressor minsan sobra lamig minsan antagal mag engage ng thermostat. Yung sensors kasi as they age parang nawawala sa calibration and service center would normally replace the assembly control unit and it cost more than just converting to manual.. One could diy it if my tech know how, yung portion lang ng relay i-wwire in series yung honeywell. Then some diode to retain the remote control functionality. Honeywell cost P1k nga pla sa ronquillo the last time i checked.
