3.6.2
Variation of Temperature Control Mode
during Pressure Equalizing
Control and Compressor Operation
Purpose
!
Conducts pressure equalizing operation on outdoor unit to prevent equalizing sound from
generating in BS unit.
Contents
!
Conducts pressure equalizing operation depending on the operating state of indoor unit. If
any of the following equalizing conditions is met, the equalization is conducted.
!
Mode variation during compressor operation(Operation mode judgement is same as 3-1
“Startup mode judgement”.) If the operation button is in OFF position, the variation of
temperature control mode on the remote controller is not recognized as the variation of
temperature control mode.
When the condition varies to Condition C before the above conditions are met, the indoor
unit in varied temperature control mode turns to thermostat OFF status by the operation
before the variation. (Switching of BS solenoid valve and indoor unit actuator is not
conducted.)
Regarding four way valve switching control, see “Four way valve switching (startup) control”.
And see the next page for the equalizing control.
