∗
If demand controlling using input B:
∗
Forced thermostat OFF command
Forces indoor unit to run the fan only.
∗
Forced temperature shift
Raises preset temperature 2˚C when cooling, and lowers 2˚C when heating.
Note:
For zone control, because the units run when RY1 is ON and go off when RY1 is OFF, when in the last
command priority mode, some units remain off during operation. 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). With
position B, constant input cannot be used for input B.
