This state is due to the following causes:
HEATING MODE
Insuffi cient water fl ow rate. Close the bypass
valve to increase heat transfer from water to water
Note: This error message will be most possibly displayed when the temperatures both of pool water and of ambient air are high.

REMARKS ON HEAT PUMP OPERATION
Heat pump effi ciency will increase with the increasing temperature of ambient air.
The achievement of required pool water temperature may take a few days. This time is quite normal and depends particularly on climatic
conditions, the volume of pool water, size of water surface area, time of heating pump operation and pool heat loss (caused by evaporation, heat
transfer through pool walls, radiation, etc.). Failing to take measures to limit the heat loss, it will not be economical, or even possible, to maintain
any higher temperature of pool water.
To limit the heat loss at the time in which the pool is out of use, a cover or solar blanket can be used.
The temperature of pool water should not exceed 30 °C. Warm water has not any refreshing eff ect and, moreover, creates favourable conditions for
microbial growth (of algae, etc.). In addition, certain pool components may have temperature limits, for instance the foils of foil pools can get soft
and lose their fi rm shape. Do not set any higher temperature than 30 °C on your thermostat.

The HP heats or cools
water until achieving its
required temperature
The HP will be put into
operation within the time
interval of 1 – 3 min in its
previously set operating
mode (heating or cooling).
The HP will stop for 3 – 4
min, its mode changes and
the HP starts in the newly
set mode.
