Setting The Operation Mode; Discharge Temperature Control - Panasonic S-140MH1H5 Operating Instructions Manual

This product brings outdoor fresh air into the building and adjusts and supplies the air with nearly current indoor temperature.
1. Automatic cooling and heating operation mode
Due to the temperature difference between the outdoor air and preset temperature in remote controller, cooling or heating
operation can be automatically selected.
In the case of group control, the setting is possible when all of the indoor units in the same refrigerant circuit consist of one
group. (P.6)
1 Cooling operation mode : In case that the outdoor temperature is 5°C higher than the preset temperature in remote
2 Fan operation mode
3 Heating operation mode : In case that the outdoor temperature is 5°C lower than the preset temperature in remote
Example: In case that the preset temperature in remote controller set at 20°C

3 Heating operation mode
2. Cooling operation mode
It is recommended that the temperature setting in remote controller be more than 24°C.
If the intake air temperature is getting higher than the preset temperature in remote controller, the unit operates in cooling
mode. On the contrary, if the intake air temperature becomes lower than the preset temperature, the unit operates in fan
mode.
3. Heating operation mode
It is recommended that the temperature setting in remote controller be set at 16°C.
If the intake air temperature is getting lower than the preset temperature in remote controller, the unit operates in heating
mode. On the contrary, if the intake air temperature becomes higher than the preset temperature, the unit operates in fan
mode.
4. Fan operation mode
In the moderate climates, supply of fresh outdoor air can provide as passive cooling.
NOTE
In general, it is recommended that you set in the automatic cooling and heating operation mode.
The setting of discharge temperature is not displayed on the remote controller. Should you wish to make changes in temperature
settings, contact the dealer where you purchased.
