At this time even if input A is ON,operation goes off and all units stop running.D) If operating by two inputs using instantaneous input for input A and B (Use instantaneous input of min.200 msec ON time.):Note: With positions 7~A, if constant input is used there is a forced OFF function (input A disregarded). Withposition B, constant input cannot be used for input B.Display SignalFetchNormal operation output terminals (W1, W2) and malfunction output terminals (W3, W4) are no voltage,constant contact output.(Allowable current is 10 mA~3 A per contact.)Output for each system is as given in the table below.Position Function of input A Function of input BC Remote controller inhibit(Same as position 5)Forced thermostat OFF commandD Forced temperature shiftE Individual (Same asposition 6)Forced thermostat OFF commandF Forced temperature shiftPosition Function Contents of input A when ON Contents of input B when ON7 Remote controller inhibit ON (remote controller normallyinhibited)OFF + remote controller inhibited8 Centralised priority ON + remote controller enabled9 OFF by remote controllerenabledON + OFF by remote controller onlyenabled (ON by remote controllerinhibited)A Remote controllerenabled / OFFRemote controller only enabled (ON byremote controller inhibited)B Individual ON (remote controller normally enabled) OFF (remote controller normallyenabled)Output Both RY1 and RY2 OFF Only RY1 ON Only RY2 ONSystemIndividual controlor individualdisplayOFF Normal operation Stop due to malfunction ortransmission malfunction betweenadaptor PC board and indoor unitGroup control OFF All normal operation Even one unit stopped due tomalfunction or transmissionmalfunction between adaptor PCboard and indoor unitZone control All OFF Even one unit operatingnormally without malfunctionEven one unit stopped due tomalfunction or transmissionmalfunction between adaptor PCboard and indoor unit
