Hysteresis of minimum operating temperature introduces a tolerance for the activation threshold temperature
preventing
unwanted oscillations at activation low temperature fluctuations. This is the difference between the heat
pump activation
temperature and the temperature of its deactivation (after the temperature drop).
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 a value of 3
°
C the pump is deactivated.
The user can decide whether the heater is to be enabled below the minimum air temperature.
This option is used to set the tank temperature hysteresis. This is the difference between the set point temperature
(desired on a
boiler - when the heat pump turns off) and a temperature of the heat pump return to work.
The ECO - ECO PLUS threshold is a tank temperature at which the generator is turned off and further tank post heating
starts
to be carried out using the heater or/and an additional heat source.
This option is used to set the temperature hysteresis for the ECO - ECO PLUS threshold (disconnection of the unit and
the
engagement of an additional heat source), in order to prevent unnecessary oscillations. This is the difference
between the
temperature of threshold disengagement of the generator and the temperature of the generator return to
work (after the
temperature drop below the ECO - ECO PLUS threshold).
The operation of the installation protection depends on the pressure switch (the pressure sensor).
In the event of the engagement of this function, the signal of the pressure switch with too high pressure disables the
pump and
triggers the alarm.
The emergency temperature is a parameter protecting the compressor and the generator from overheating. In the
event of a
dangerous increase in the temperature of the control sensor (up to an emergency temperature) 3 times within
an hour the
generator disengages permanently. In this case the restart of the device is only possible via the heat pump
manufacturer
service.
After starting the heat pump, first engages the ventilator and the pump, and then after a few seconds, the compressor.
This
setting adjusts the time delay of the compressor engagement after the ventilator and the pump. When the pump is
about to
disengage (e.g.: the ECO - ECO PLUS threshold temperature is to be reached), first the compressor is
disengaged and after a
set time delay, the ventilator and the pump.
This parameter is closely linked with the emergency temperature function. If the control temperature exceeds the
emergency
threshold 3 times within an hour, it is possible to heat only with the heater.
Using this setting it is possible to edit the service phone number, which is displayed in the user menu: Information. Set
the
desired value by turning the encoder, accept the choice by pressing the encoder.
With this function you can change the access code to the service menu. Set the desired value by turning the encoder,
accept the
choice by pressing the encoder.
The controller is pre-configured to work. However, it should be adjusted to your needs. You can return to the factory
settings
at any time. When enabling the option of factory settings all custom settings of the heat pump are lost (stored in
user menu) to
the settings stored by the controller manufacturer. From this point you can re-set your own service
parameters of the heat
pump.
