(2) Non- polar two-wire remote controller cable
The slim, non-polar, two-wire remote controller cable makes installation simple and troublefree. Also, the remote con-
troller wire can be extended up to 500m.
(3)Automatic cooling / heating changeover operation
An automatic cooling and heating changeover operation system allows you to easily control comfortable year-round air
conditioning.
Once the desired temperature is set, unit operation switches automatically between cooling and heating, in accordance
with the room temperature. In addition, the use of an outdoor unit fan speed controller allows cooling even when out-
door temperatures are as low as -5 °C.
5. INNOVATIVE MICROPROCESSOR CONTROL SYSTEM
The most significant feature of PEH-EKH(S)A series is the advanced microprocessor control. The development of this sys-
tem is due to the recent world-wide trend in the air conditioning of larger buildings. They are moving away form centralized
duct systems to using individual split type units instead. There are a number of reasons for this change. First of all, the duct
´s costly and troublesome installation is eliminated. Second, the overall air conditioning balance is excellent in split type units.
Lastly, the operation costs are low due to the flexible control of each unit. This system was developed exclusively by
Mitsubishi Electric because of high demand. The microprocessor control makes individual control, group control, control
using two remote controllers, remote on / off control and individual control possible without troublesome equipment modifi-
cations.
