Sanyo SAP-CMRV1926EH Manual Do Utilizador

The numerical values such as temperature, frequency, time and current in parentheses are an example 
of SAP-CMRV3146EH and the values are different from the other models.

Breaker is ON.

Power is supplied to the indoor and outdoor unit 

control circuits, however the unit remains stopped.

Positioning of the outdoor unit electric expansion 

valve is performed.

The ON/OFF operation 

button on the remote 

controller is pressed.

If automatic operation mode has been selected 

with the remote controller, operation begins in 

HEAT, SENSOR DRY, or COOL mode 

depending on the room temperature and 

outdoor temperature at the time operation starts.

Depending on the operational mode, refer to the HEAT, SENSOR DRY, or COOL item.

This applies in the case of automatic 

HEAT/COOL operation.

The ON/OFF operation 

button on the remote 

controller is pressed.

The unit is forced to stop for 3 minutes after 

the power is turned ON, or 3 minutes after the 

compressor stops, in order to protect the 

compressor.
The frequency is increased at the rate of 1 Hz 

every 0.5 seconds.

Operation lamp illuminates.
Indoor fan is stopped to prevent cold air from 

being emitted.
Outdoor unit begins operating after 

forced-stop is canceled.

This is in order to stabilize the return of oil to the 

compressor.

When the frequency reaches    Hz,frequency 

increases are stopped for a period of    seconds. 
(Refor to Table 2 "Freguency control".)

If the indoor and outdoor temperatures are high, 

the current peak cut-off activates, stopping any 

increases in frequency.

The frequency then increases.

The thermostat turns 

OFF.

The outdoor unit stops. (It does not stop if the 

thermostat for another indoor unit is ON.)
Approximately 30 seconds after the 

thermostat turns OFF, the indoor fan is 

stopped.

The indoor fan is stopped.

The indoor and outdoor 

temperatures are high.

The outdoor unit starts automatically after 3 

minutes.
During these 3 minutes, a low-pressure 

pressure balance is achieved, allowing the 

compressor to start more easily.

In order to protect the compressor, the outdoor 

unit will not operate for 3 minutes after the 

thermostat turns OFF, even if the room 

temperature drops below the desired 

temperature.

The room temperature 

has reached the desired 

temperature.

Operating frequency is stabilized in order to 

maintain a comfortable environment.

The indoor temperature and the remote 

controller temperature setting are 

approximately equal.

The thermostat turns ON.

The unit operated before, and the temperature of 

the indoor heat exchanger is relatively warm.

Therefore,the fan speed may start at the set fan 

speed at the same time that the thermostat turns 

ON.

The indoor unit is stopped.

Depending on the relationship between the 

remote controller temperature setting and the 

room temperature, the compressor may stop 

temporarily (in other words, the thermostat 

may turn OFF).

When the indoor coil temperature rises,
the compressor starts,
the outdoor fan starts,
and the indoor fan changes from "LL" 

to the set fan speed.

The amount of heat pump exceeds the amount 

of heat radiation from the room.

Therefore, there is no need to further increase 

the compressor capacity, and the frequency is 

stabilized or lowered.

The frequency is not increased, even if 

there is a difference between the room 

temperature and the desired temperature.

In some cases, the frequency may be 

decreased.
