1. Solenoid Type: Upon initial start-up the connected solenoid type is checked by the controller; it must be a DC latch solenoid for BERMAD applications. The word dC appears on screen indicating that the type of solenoid found is DC. When the controller is operated by a 9V battery the solenoid type is DC only and it cannot be changed by the operator. - Page 11 Second Basic Settings Screen In the second setting screen the operator can set the Flow Switch usage mode. Please note that a flow switch can be used only for BERMAD’s pressure management application. Flow switch mode: Press the button to enable or disable the flow switch operation.
- Page 12 Normally the high pressure pilot controls the valve, while the low pressure pilot is on standby mode. A Subtv controller with a DC solenoid can switch the high pressure pilot with the low pressure pilot according to a pre defined time based operation regime.
- Page 13 Operating the valve with the Subtv controller reduces the too high pressure settings during the low demand hours. For example, in typical such pressure regime, the day low pressure hours are between 10:00 AM and 06:00 PM and the night low pressure hours are between 10:00 PM and 06:00 AM, during the high demand hours the valve maintains the high pressure setting.
- Page 14 BERMAD’s control valves equipped with Subtv controllers can be installed in these systems. BERMAD’s Dead-end Pipes Purging Application accounts for the purging out of the system. This task is automatically performed based on three major parameters: 1.
- Page 15 2. Operation Days: Use the to set a particular day as an operation day, the cursor will advance to the next day. In our example set Monday and Friday for operation. Press the button to move to the next programming screen which is the Start Times screen.
- Page 16 In order to operate the above program the system should be based on BERMAD’s series Hydrometer, or on other BERMAD’s control valve and a water meter. The Subtv controller should be also set to volumetric operation, which can be done only at the...
- Page 17 initial setup process of the controller (when power is connected or when the controller’s reset operation is performed). 1. Operation Volume: Make sure that the controller is configured for Volume operation as described in the BASIC SETTINGS chapter at the beginning of this document.
- Page 18 Fill-Up Time (F.U.T.) - indicated by the on-screen icon. This parameter defines the time it takes to fill-up the system pipes at the beginning of the valve operation. During this time the system does not enter to High Flow fault. In purging systems where the purged water is released by open-end pipe to the atmospheric pressure, the flow rate can be high.

Page 19: Monitoring
Monitoring When no button is pressed in the controller’s keyboard for 3 minutes, the controller moves to the main monitoring screen indicated by the word AUTO in the middle of the screen. The AUTO screen displays the current status of the controller, which includes the current time and day, as well as the opened valve indication and its remaining operation time or volume. -
Page 20: Manual Operation
Please note that when manually started, the valve operates for the duration of its programmed operation time or operation volume. Disclaimer The Subtv is a general purpose controller supplied as an electronic device controlling BERMAD valves.
