Hysteresis of HUW
Below temperature Preset HUW temp. minus
HUW hysteresis the HUW pump will activate
to feed the HUW container.
By small hysteresis value HUW
pump will activate faster after HUW
temperature decrease.

all the inmates about activating the
disinfection function. There is a
danger of scalding with hot water.
Once a week at night, in Monday at 2 a.m.
the controller increases temperature of HUW
container. After 10minutes of keeping the
silo at 70ºC the HUW pump is deactivated
and the silo returns to its normal operation.

thermostat should be set. (parameters Mixer
room thermostat, e.g. 5ºC. This value should
be
chosen
experimentally.
A
room
thermostat can be a traditional one or a
room panel. After activating the thermostat,
mixer preset temperature will be reduced.
When this value is reduced correctly then
room temperature increase will be stopped.
