Keyboard oventrop OV-DMC 2 The flow meter is activated by using the key . The flow meter is switched on by pressing the key for about 1 second and is switched off by pressing it for about 3 seconds (only possible in the main menu). Before the flow meter switches off completely, some data is saved and it is checked (with the measuring head being connected) whether the bypass inside the measuring head is opened. -
Page 12: Main Menu
If the flow meter is switched on with the measuring head being connected (keep key pressed for about 1 sec.), not only “oventrop” but also the 4- digit number of the flow meter appears in the lower left edge and the 2-digit software version in the lower right edge. -

Page 20: Ov-Balance
OV-Balance OV-Balance: This regulation method is an advancement of the compensation method. The advantage of the OV-Balance is that the complete supply system may be balanced by only one person. The time required for the hydronic balance is reduced considerably provided that the installation is structured clearly and a consecutive numbering of all regulating valves is summarised in regulating groups. - Page 21 OV-Balance Before carrying out the on site regulation, it has to be verified whether all isolating valves within the circuit are opened. Moreover it must be ensured that the installation corresponds to the design condition, e.g. ther- mostatic radiator valves preset, thermostatic head removed. Sequence of regulation: 1.
