value. Nevertheless in order to avoid frequent servo movements
which can shorten its life, adjustment is carried out only when the
measured water temperature is lower or higher than the mixer
dead zone.

Drying is performed by a corresponding change in floor circuit
temperature in the range 10..50ºC in a time of 30 days. Drying can
be deactivating at any time. Re-activation function makes that the
drying works all over again for 30 days.
Activating or Deactivating the screed floor drying function (heating
by floor circuit).
OFF – disables operation of DHW tank,
ON – enables operation of HUW tank.
Minimum preset temperature of water in the DHW tank.
Maximum preset temperature of water in the tank. This parameter
determines the maximum temperature to which the DHW tank will
be heated while discharging exceeding boiler heat from a boiler
or solar collector. Setting too high value can lead to the risk of
scalding with DHW. Too low parameter value will eliminate a
possibility of discharging heat excess to the DHW tank when the
boiler is overheated. In installations including a solar system, too
low value will reduce heat contacts because the solar pump loads
the DHW tank to a DHW maximum temperature. DHW system
developer should consider a possibility of the controller failure.
Such failure can cause heating the water inside DHW tank up to
a hazardous temperature causing a risk of scalding for users.
Therefore, thermostatic valves should be used as an additional
protection.
OFF – DHW tank loading at enabled heating circuits
(simultaneously),
ON – HUW tank loading at disabled heating circuits.
When DHW tank is charged and DHW pump is switched off, boiler
may overheat. This problem is related to work of the DHW pump
in SUMMER mode (when heating circuits pumps are switched
OFF). In order to cool down the boiler, work time of the DHW
pump can be extended by time value from this parameter.
OFF – disables the DHW circulating pump operation,
ON – enables the DHW circulating pump operation.
Intervals between activation of circulating pump is defined with
DHW pump circulation
(recommended setting 15...40min,). Circulating pump works
cyclically for a DHW
(recommended setting 60...120 s.)
In order to save electrical energy the DHW circulating pump will
be disabled when the DHW temperature is lower than Circulation
pump start temperature.
DHW tank will be loaded up to a preset temperature. When
temperature of water inside the tank drops by DHW hysteresis
