ECO+ THRESHOLD HYSTERESIS
This option is used to set the temperature hysteresis for the ECO
–
ECO+ threshold (switching the compressor off and switching
the additional heat source on), in order to prevent unnecessary oscillations. It is the difference between the threshold compressor
deactivation temperature and the temperature at which the compressor returns to work (after the temperature drops below the
ECO-ECO+ threshold).
INSTALLATION SECURITY
The operation of the installation protection function depends on the pressure switch, namely the differential pressure sensor. In the case
of switching this function on, the signal from the pressure switch relay about too high pressure will switch the compressor off and activate
the alarm.
EMERGENCY TEMPERATURE
Emergency temperature is a parameter protecting the cooling system against overheating. In the case of a hazardous increase in the
compressor's temperature (up to the emergency temperature), the control sensor will be permanently switched off and the system shut
down. In such a case, repeated activation of the device is only possible with the help of the heat pump manufacturer's service staff or
when the alarm is removed from the controller's service menu.
COMPRESSOR DELAY
After turning on the heat pump, the fan is activated first, and then, after a few seconds, the compressor. This setting is regulated by the delay
time for compressor activation after the fan. When the heat pump reaches the ECO
–
ECO+ threshold, the compressor is turned off first, and,
after the set delay, the fan.
MINIMUM COMPRESSOR STOPPAGE TIME
This parameter allows you to determine the compressor's minimum necessary break time after a water heating cycle.
HIGH PRESSURE SWITCH
The parameter allows you to select the applied type of high-pressure detecting control switch
–
contact or break contact.
LOW PRESSURE SWITCH
The parameter allows you to select the applied type of low-pressure detecting control switch
–
contact or break contact.
LEGIONELLA
6.17.1
LEGIONELLA FUNCTION TEMPERATURE
This is the preset temperature of thermal disinfection (
LEGIONELLA FUNCTION
).
6.17.2
LEGIONELLA FUNCTION DURATION
Using this function, the duration of the disinfection is set (in minutes) in which the preset disinfection temperature will be maintained on a
constant set level (
LEGIONELLA FUNCTION TEMPERATURE
)
.
6.17.3
MAXIMUM LEGIONELLA FUNCTION TIME
This is a maximum total duration of the disinfection (
LEGIONELLA FUNCTION
) from the moment of activation (regardless of the temperature
when switched on). In the event that the tank does not reach the set disinfection temperature or does not maintain the set temperature for the
time of the LEGIONELLA function, then, after the maximum time, the controller will return to the basic operation mode.
6.17.4
LEGIONELLA FUNCTION REMINDER
In this submenu, the user can select the legionella mode between legionella reminder and legionella autostart. In the
REMINDER
–
NUMBER OF DAYS
function the user specifies the number of days after which a reminder about legionella will be provided
