Control Technologies
05-06
The adoption of dot liquid-crystal display (LCD) technology and a
large display screen for the control panel optimises visibility. Opera-
tion and control status are easily read at a glance.
The upper and lower limits for the temperature range during
operation can be set. This prevents excessive heating or
cooling, leading to increased energy savings.
Set the time for the air conditioner to turn off automatically. The
timer can be set in the range from 30 minutes up to 4 hours in
30-minute intervals.
* The “Simple Timer,” which can be set at one-hour intervals, is set at the
time of shipment from the factory. It can be changed to the “Auto-off
Timer” function using the remote controller.
* Only the administrator can change settings when using the Operation
Lock mode.
Units can be set so that the operation mode cannot be changed.
When “Operation Lock” is activated, new temperature setting
commands are not accepted, thereby ensuring that the unit runs
in the specified (locked in) temperature range. This promotes
energy savings and prevents erroneous or mischievous operation.
Weekly Timer – Introduced in Response to
Market Demand
Control temperature on a weekly basis
Temperature settings and On/Off control can be managed over a
period of one week using the Weekly Timer. Up to eight setting
patterns per calendar day are possible.
Easy Maintenance Function
(Mr. SLIM Power Inverter only)
Nearly maintenance-free operation
Monitor operation data of the indoor and outdoor
units via the remote controller. The remote control-
ler also lets you set the operating frequency,
allowing easier inspection.
Refrigerant Leakage Check
(Mr. SLIM Power Inverter only)
Mr. Slim Power Inverter units come equipped with a
useful new “Refrigerant Leakage Check” function.
Using a wired remote controller, it is easy to check
if refrigerant has been lost over a long period of use.
This reduces service time and gives an added
sense of safety.
Setting the temperature 1°C higher for cooling and 1°C lower
for heating results in an energy savings of approximately 10%.
