information in the corresponding installation manual. Note the following information
on initial commissioning:
•
The control unit is connected to the primary tank and the secondary tanks, if
provided.
•
The water connections of the tanks to the facility system are established.
•
The tanks are not filled with water.
•
The valves for emptying the tanks are open.
•
The facility system is filled with water and gas-vented.
•
The electrical connection has been created according to applicable national
and local regulations.
8.2 Variomat switching points
The "P " minimum operating pressure is determined by the location of the
0
pressurisation. The controller calculates the switching points for the solenoid valve
"PV" and the pump "PU" from the "P
