The VXTC is designed to operate with all major boiler level controls. When the VXTC receives a
low water signal from the boiler control, it delays (from 0 to 10 minutes) to allow condensate to return to the boiler. If make-up water is required following the delay period, the VXTC
initiates a feed cycle. This cycle can be programmed to feed to the level of the boiler control or can be fine-tuned to a desired level above the boiler control. The heavy-duty cast bronze water meter tracks all water fed into the system. The VXTC includes a water feeder, strainer, flow restrictor and water meter with 3/4" NPT fittings.
