“Checking water temperature” – the temperature of the water is being determined. Apart from the
time condition given in the previous point, other conditions must also be met (the validity of the
measured temperatures, the output is not restricted by a time schedule).
“Water temperature determined” – it signals that the checking of the water temperature has been
completed. This indicator is lit practically nonstop, it is only not active after the reset of the controller
or possibly at the time when the outputs are restricted by the time schedule.
“Thermal control request” – the thermal control requires the operation of the circulation pump and
circulation. Apart from the required temperature condition, other conditions must also be met (the
pool heating is not blocked due to heating of the house, the low tariff must be active if the “Run in low
tariff only” option has been ticked, etc.).
“Tank cool down request” – the storage tank requires cooling down into the pool.
“Circulation pump request” – it signals the operation of the circulation pump and circulation.
“Filtering pump request” – it signals the operation of the filtering pump.
“Pool heating indicator” – it informs the other control blocks about a current or recent request for
pool heating. This indicator is always activated by the switching on of the circulation pump and
circulation as a result of thermal control and it is deactivated after the time which is set by the “Pool
heating indicator off-delay” item has passed.
“Measured water temperature” – the currently measured water temperature by the sensor. If the
circulation pump or circulation are not running, it shows the temperature of water in the vicinity of
the sensor, but this temperature does not have to correspond to the real temperature of the water in
the pool.
“Heat source temperature” – it shows the heat source temperature, typically near the offtake of heat
from the storage tank into the pool heating circuit.
“Last determined water temperature” – it shows the last determined water temperature in the pool. If
the circulation pump and circulation are running, the last determined water temperature corresponds
to the measured temperature of the water in the pool.
“Checking water temperature – timer” – it shows the remaining time until the next determination of
water temperature.
“Current filtering time” – it shows the current filtering time relevant for the last determined water
temperature.
“Pool heating indicator off-timer” – it shows the remaining time until the deactivation of the pool
heating indicator.
“Required water temperature“ – it shows the required temperature of the pool water. If we wish to
heat the pool only during the warm season (summer), in autumn we reduce the temperature to the
value at which it does not freeze (3-5°C) and at the beginning of summer we re-set it to the required
value. In the case of winterizing the pool we do not have to set anything, we only disconnect the
pumps or switch off their circuit breakers.
“Temperature hysteresis” – it shows the temperature hysteresis for controlling the pool water
temperature. If the current temperature of the pool water is lower than the required temperature,
the circulation pump will switch on. If the current temperature of the pool water is higher than the
required temperature plus hysteresis, the circulation pump will switch off. We recommend that you
choose the values from 0.5 to 1 °C. Due to the required precision and the probable long distance of
