10. Indoor Unit Control of the Electronic Control Valve
10-1. Normal Control
(1) Except Type E1
(1) Type E1
*1 The SH target value is controlled so that the difference [E3 - E1] can become 2 - 6°C, depending on the
operation conditions. However, a decline in the required level may cause the SH target value to increase.
Be aware that in this case, the electronic control valve is intended to close and this will be wrongly identified
as gas shortages.
*2 The SC target value is controlled so that the difference [pressure temp. sensor E1] can become 5 - 20°C,
depending on the operating conditions.
*3 In the case of the common use electronic valve kit and more than one (1) indoor unit in the heating mode
within the same electronic valve kit, performs the control of returning the liquid refrigerant
gradually into the outdoor unit in the range of 55 - 80 pulses.
*4 The SC target value is controlled so that the difference [pressure temp. sensor - E1] can become 5 - 20°C,
depending on the operating conditions. However, if installation is combined with the except type E1,
the value is controlled so that the difference [pressure temp. sensor - E1] can become 5 - 40°C.
