Example : when the minimum operating temperature is set to 5°C and the hysteresis is set at 2°C, the
heat pump activates at 5°C, but when the temperature drops to 3°C the unit is deactivated.
7.10 Heater operation below min. operation temp.
Activates the operation of the heater if the outside temperature is lower than the value set in
parameter 7.8 Minimum operating temperature.
7.11 Tank set. temp hysteresis
This option is used to set the tank temperature hysteresis. This is the difference between the set
point temperature (desired on a DHW tank - when the heat pump turns off) and a temperature of
the heat pump activation.
7.12 ECO-ECO+ threshold temp.
The ECO - ECO PLUS threshold is a tank temperature at which the unit is turned off and further tank
post heating starts to be carried out using the electric heater or/and an additional heat source.
7.13 ECO-ECO+ threshold hyst.
This option is used to set the temperature hysteresis for the ECO - ECO PLUS threshold
(disconnection of the unit and activation of an additional heat source), in order to prevent
unnecessary oscillations. This is the difference between the temperature of deactivation of the unit
and the temperature of the compressor reactivation (after the temperature drop below the ECO -
ECO PLUS threshold).
7.14 Installation security
The operation of the installation protection depends on the pressure switch (the pressure sensor). If
this function is activated, the pressure switch will send the signal about too high or too low pressure
therefore, switching off pump and triggering the alarm.
7.15 Emergency temperature
The emergency temperature is a parameter protecting the unit and the compressor from
overheating. If the temperature of the control sensor dangerously increase (up to an emergency
temperature) 3 times within an hour the compressor will shut off permanently. In this case, the
device can be restarted after the control temperature alarm has been cleared. The controller will
emergencyally turn on the heater output in order to heat the tank.
7.16 Compressor delay
After starting the heat pump, the fan and the pump are activated first, and then after a few seconds,
the compressor. This setting adjusts the time delay of the compressor. When the pump is about to
switch off (e.g.: the ECO - ECO PLUS threshold temperature is to be reached), the compressor is
deactivated and after a set time delay, the fan and the pump are also deactivated.
7.17 Delay of the low pressure switch
The time that determines the delay in the activation of the low-pressure switch. After four
consecutive low-pressure alarms, the heat pump is blocked and an error message appears: low
pressure switch error.
