ELECTRICAL CONNECTION

4.3.1

CONNECTION TO THE MAINS

IMPORTANT: The heat pump is supplied with a power supply cable provided with the plug for connecting it to the
mains socket. Socket installation shall meet the requirements of the ČSN 33 2000 standard, including adequate
protection and installation of a residual-current circuit breaker (RCCB) of the actuating current not exceeding 30 mA.
The use of a double socket with common switching (by a switch or a timer) is recommended.
The heat pump ON/OFF switching is described in chapters 5 and 6.
4.3.2

PERMANENT ELECTRICAL CONNECTION

IMPORTANT: In case you decide to connect your heat pump permanently it will mean an intervention
into its wiring that shall be carried out only by a specialist of appropriate technical qualification and the
installation shall meet the following requirements:
(a) The heat pump together with the power supply for the pump of filtration unit shall be connected via a separate circuit breaker and switch, or, possibly, a timer for
its regular starting. The supply cable shall be of adequate size (the cable of 3x2.5 mm2 cross section is recommended) and provided with a residual-current circuit
breaker (RCCB) of the actuating current not exceeding 30 mA. The parameters of power network (voltage & frequency) shall comply with the equipment ones.
(b) The electrical connection shall be carried out by a duly qualified technician in compliance with applicable IEC regulations and standards.
(c) The pump wiring shall be properly grounded. The impedance of grounding circuit shall meet applicable IEC regulations and standards.
(d) The power and control cables shall be wired and laid in the simplest and easy to understand way, without any useless crossing.
(e) Before putting it into operation, the wiring system should be carefully checked and measured with the view to eliminating any erroneous connections.
(f) The following table gives the data of recommended protection:

Press the
In the standby state the LED panel shows the actual time (if set).
In the operating state the LED panel displays the current water temperature.

OPERATIONAL PARAMETER SETTING AND CHECKING

In the standby state (OFF) press the key ◄ or ► to enable the setting interface. By repeated pressing of keys ◄ or ► display the parameters 0 – F,
see the table below.
Select the parameter you wish to change and press the SET key. Make the required change in its value by operating the keys ◄ and ► . Press the SET
key again to store the adjusted value and finish the process.
By operating the keys ◄ and ► in the operating state the set and measured values can be checked. However, no parameters may be changed,
excepting setting the target temperatures of water, i.e., parameters 0, 1 and 2.
If no key is pressed in the course of setting/checking process within the period of approx. 8 s, the screen will change over automatically into its standard display mode.

Notes on the table of operating parameters:
Parameters from 3 to 6 – Automatic defrosting setting:
If the temperature sensor on the evaporator reads a lower temperature than set by Parameter 4 checked in regular intervals given by Parameter 3, the system will
switch over into the defrosting mode and terminate this mode after either of the values (temperatures) set in Parameter 5 and Parameter 6 has been achieved.
Parameter 8 – temperature at compressor outlet:
The temperature sensor switches the equipment OFF after achieving the set temperature. It is recommended not to change the factory setting.
