The function allows to enable individual devices regardless to other to verify its operation. Enable individual devices by
pressing the encoder when highlighted: ventilator, compressor, heater, main pump, circulation pump and additional
pump.
LEGIONELLA function is used to disinfect the tank. In the service menu you can configure individual parameters of this
function.
When editing set the desired value by turning the encoder, accept the choice by pressing the encoder.
The function allows to define the set-point temperature of disinfection.
Using this function sets the duration of the disinfection (in minutes) in which the set-point temperature of disinfection
stays at
a constant set level (Legionella temperature).
This is the maximum total duration of disinfection (LEGIONELLA function) since the engagement (regardless of the
temperature during the engagement). In the case when the tank does not reach the set-point temperature or does not
maintain
for the duration of the LEGIONELLA function set-point temperature, then after a maximum time the controller
will return to the basic operating mode.
When the user activates this function, the controller displays the reminder of disinfection function. The message
appears after
10 days from the last engagement of this function.
Defrosting can occur when the external temperature drops below the T defrost parameter - a parameter set in the
serviceevaporator defrost tab and when the temperature of the evaporator reaches the set value. Defrost is carried out
until the evaporator reaches the end evaporator defrost temperature - a parameter to set in the service tab. Defrost is
limited in time by the max defrost duration parameter. If during this time the evaporator cannot be effectively
defrosted, the heat pump switches to the 10 minute pre-heating cycle, and then again a process of defrosting. After 3
unsuccessful attempts of defrosting the defrost error message is displayed. The heat pump is locked. All the protection
functions remain active. The heat pump reset takes place e.g. when power is disconnected.
Additionally in the controller there is available function of manual defrost - service tab Manual defrosting
should be used in emergency situations (strong evaporator frosting).
In the tab defrost parameter - service , the user can set the following parameters:
evaporator temperature (range from +5 ° C to -15 ° C)
final evaporator temperature (range from +5 ° C to +25 ° C )
external temperature (range from +10 ° C to +2 ° C )
At the certain external temperature or below this temperature thawing is carried out at the set evaporator
temperature or below this temperature. Evaporator temperature at which the thawing is carried out should maintain for
the min. 15s. After this time the evaporator defrost is activated.
In the Service - defrost parameter tab there is located LP monitoring function (low pressure switch) during
defrosting. Functions to select: No LP monitoring, LP monitoring active . In the case of active function of No LP
monitoring the signal from the low pressure switch is not taken into account by the controller during the evaporator
defrost.
