AG-WT10 – an excellent choice
AG-WT10 is part of a complete, modern heat pump system that offers ef-
fective technical energy saving and reduced carbon dioxide emissions. The
integrated control system in the indoor unit gives safe and economical
climate control.
The heat is retrieved from the outdoor air by means of an outdoor unit
(AG-AA10), where the refrigerant, which circulates in a closed system,
transfers the heat from the heat source (the outdoor air) to the indoor
unit (AG-WT10).
Excellent properties for AG-WT10:
■iFEEL
The iFEEL function has been developed to obtain the best possible
comfort. The iFEEL function uses the remote control's integrated tem-
perature sensor to adjust the room temperature based on where the
remote control is in the room. For best results the remote control should
be positioned so that the communication line between the remote
control and indoor unit is as direct as possible.
■Inverter controlled compressor
The heat pump has an inverter controlled compressor that automatically
adapts itself optimally and economically to your home's energy require-
ment.
■Air ioniser
AG-WT10 is equipped with an air ioniser that effectively prevents bad
air and eliminates bacteria and microorganisms.
■Night program
With the night program, the temperature and fan speed are adjusted
to save energy without affecting the comfort of the premises.
■High power
With the High Power function activated, the climate unit works at the
maximum cooling or heating power.

17AG-WT10Chapter 4 | Function modes

Heating
1. Press button until the symbol for heating ( ) appears on the
display. If the symbol lights continuously the fan stops at the achieved,
desired temperature. If it flashes, the fan is running even after the
desired temperature has been reached.
2. Press the +/- button (temperature selection) to set the desired temper-
ature (the setting range can be set between 10 °C and 32 °C).
The display indicates the selected temperature value.
Once five minutes have passed after setting the desired
temperature, the display resumes to showing the room
temperature.
3. Press the button to set the fan speed.
NOTE
After the heating function is activated, the fan stops. This is because the
”Prevention of cold air” function is active and activates the fan's normal
function, only after the indoor unit's heat exchanger is sufficiently warm.
During this period the function lamp stays lit (red lamp).
Defrosting the outdoor unit's heat exchanger
When the outdoor temperature drops below zero on the external heat
exchanger, ice builds-up that reduces the heating output. When this occurs,
a function activates that defrosts the heat exchanger. In these operating
conditions, the internal fan stops. The heating function resumes after a
few minutes, depending on the room and outdoor temperature.
