The HP will stop for 3 – 4
min, its mode changes and
the HP starts in the newly
set mode.
HEATING MODE
Insuffi cient water fl ow rate. Close the bypass
valve to increase heat transfer
from water to water
COOLING MODE
Too high water fl ow rate. Open the bypass valve to reduce
water fl ow rate and increase thereby the heat transfer
from water to coolant
.
Insuffi cient fl ow of air. Make sure that evaporator
lamellae are not fouled.
Note:
This error message will be most possibly displayed when the temperatures both of pool water and of ambient air are high.
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
