hi, the accounts department at works air con has stopped working, it is a mitsubishi mr slim master and slave system. i installed them in 2000 but they use a outside contractor to maintain them, the fault was the indoor air temperature probe has failed

both air con units were oversized to cope with a office extention that never took place, so im happy that one unit can cope for the short term

now unless im wrong, to get one of the units to run again, all i would need to do disconnect the master and slave wire link, change the dip switch settings

is this right??????

the contractor has quoted 2 weeks delivery time on the new probe and an office with 16 people in it are not happy!!!!!
