The operation of the system may be controlled on the control panel.
(cf. sect. 3.4.4, Fig. 2)
From the above figure it appears which pumps and water supplies have been connected at the
moment (
green), and the status of the pressure, water flow and water level (yellow).
Below is an example of the indications on the control panel in a given situation.
Fig. 5
1 The water level in the water tank is low - water is being
2 filled from the cold connection and
3 from the hot connection.
4 Temperature adjustment is active (set. 50°C)
5 Pumps no. 1, 3, 4 and 5 have been connected
6 Consumption is lower than the capacity from the
connected number of pumps. Water is therefore being
recirculated (the first connected pump will stop after 15 sec.)
7 The line pressure is on working pressure,
H (= high pressure)
and consequently also >25 bar, L (= low pressure)
