1. Ubushuhe buraduga ariko ntibushika ku ntumbero:
1) Suzuma thermostat. Ivyo birimwo n’ingene thermostat imeze, igipimo c’inguvu z’isohoka (niba thermostat ifise iki gikorwa), indishi y’ubushuhe bw’ubushuhe, igikorwa c’ubushuhe n’imiterere ya PID, n’ibipimo vya PID (raba ivyagezwe vy’uruganda).
2) Suzuma ibikoresho vyo gushusha no gushusha uruzitiro rwo kugenzura. Amafuru amwamwe akoresha imigwi y’ugushusha. Suzuma ko umugwi wose uriko urakora neza. Koresha ammeter-on ammeter kugira ngo upime umuyagankuba ku gice c’umugwi wose w’ubushuhe, canke uce ibishushanya no gupima ubushobozi bwavyo bwo guhangana.
2. Ubushuhe ntibuduga canke igikoresho co gushushanya ntigishusha:
1) Suzuma ibimenyetso n’imiterere y’ivyo bikoresho.
2) Suzuma ibikoresho vyo gushusha no kugenzura, harimwo n’uko AC ikora neza ikora neza, nimba igikoresho co gutera umuriro gishushanya, be n’uko iyo nzira y’imbere ikora neza.
