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.
Note: The factory setting may diff er from the data shown in the table.
Note: It is recommended not to change any setting marked with the word NO.
Connect the equipment to the mains (switch the circuit breaker on).
After switching the system on, press the
key. In operation the display shows the temperature of water at the heat exchanger inlet and the heating
mode symbol.
Press the
key to switch the heat pump off . The equipment will then stay in the standby state.
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.
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 fi nish 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.
