TDV-B Timed Discharge Valve (Battery Powered) – Water Supply in Regular Intervals
The unit is battery powered making it ideal for remote sites where mains electricity is unavailable. The control is also suitable for replenishing trap seals due to evaporation.
The TDV-B uses quartz crystal-controlled timekeeping and low power technology supporting an average battery life of up to four years. The control is easy to set up with a wide range of user selectable time intervals including hourly, four times daily, twice daily, daily, every two days and twice weekly.
The volume of water which is discharged is determined by the valve opening time. This can simply be set using the internal pushbutton or (without removing the front cover) using the Magi-Test wand. The control can be configured to discharge any volume, from a fraction of a litre per week to multiple litres per hour covering most applications.
A low battery status warning is provided by the LED which blinks every two seconds.
We recommend a procedure is put in place to change the batteries at least every two to three years.
