10.5.1. Different operating mode start conditions
Each mode of operation must meet specific conditions to be activated:
• AUTOMATIC mode
The condition to activate this function is as follows: lower probe <SP2 - r0 (hysteresis).
• ECONOMY mode
The condition to activate this function is as follows: lower probe <SP1 - r0 (hysteresis).
• OVERBOOST mode
The condition to activate this function is as follows: lower probe <SP3 and upper probe <SP3. When
a temperature higher than SP3 is detected, the overboost operating mode is terminates and the pre-
viously established operating mode is restored.
10.5.2. Screen
If the product is “ON”, during normal operation the display will show the temperature set (parameter
P5):
• If P5 = 0, the display will show the temperature of the upper part of the tank.
• If P5 = 1, the display will show the active working set point.
• If P5 = 2, the display will show the temperature of the bottom of the tank.
• If P5 = 3, the display will show the evaporator temperature.
• If the equipment is in the “stand-by” state, the screen will turn off.
10.5.3. Alarms & errors
A “UtL” alarm (fan fault) will display on the screen and emit an audible signal that can be turned off
by pressing any button on the controller.
If a “UtL” alarm occurs, you must contact our Technical
Support team on 0203 321 5929. An alarm is never cancelled unless the device is switched off or put
in stand-by mode. The heat pump operating mode is automatically disabled and the electric heating
elements enabled in order to ensure the continuity of the hot water supply.
