7 SYSTEM OPERATION

ITS heat pumps are equipped with a state-of-the-art digital controller. The controller is pre-
programmed by the installer and automates all the heat pump functions. The controller also has
extensive system diagnostics and will display a relevant error code should an error accur.
Below is an image of the controller's digital display user interface.

7.1 HEAT PUMP POWER ON

When the power to the heat pump is switched on the controller will display the full screen for a
few seconds. This shows that all segments are working on the display and power is connected.
When the heat pump is in standby (off) mode the controller displays only the time and not any
temperatures. This is shown in the left side image below. To switch the heat pump on press the
power on button on the display.
When the heat pump is in running (on) mode the controller displays the time, the water
temperature in the bottom of the tank and the temperature of the water out of the heat pump.
This is shown in the right side image below.
