• Programmable Feed Delay Settings: Prevents over filling by

allowing time for condensate to return to the boiler before initiating a

feed cycle.

• Programmable Feed Amount Settings: Includes one setting to raise

the water level to the boiler control and five additional settings to raise

the water level above the boiler control.

• LED Status Indicator: Displays mode of operation. Also provides

timer for convenient set-up of programmable feed amount setting.

• Manual Feed Button: Allows for manual feeds with the touch of a

button.

• Lock-Out Flood Protection: Locks out after sustained 10 minute feed

cycle to prevent flooding.

• Water Meter: Heavy duty meter tracks make-up water added to

system. (Not included with Model VXTC-WF).

Be sure ﬂow arrows on solenoid, meter

and strainer are aligned correctly. Use

teﬂon tape between meter and solenoid

INSTALLATION

WARNING

Frozen pipes/water damage. Central heating systems are prone to shut down as a result of power or fuel outages,

safety related fault conditions or equipment failure. Installation of freeze protection monitoring or other precautions is recom-

mended for unattended dwellings in climates subject to sustain below-freezing temperatures.

WARNING

Electrical shock hazard. To prevent electrical shock, dea th or equipment damage, disconnect power supply before installing

or servicing control. Only qualiﬁed personnel may install or service this control in accordance with local codes and ordinances.

Read instructions completely before proceeding.

Prior to piping, remove the solenoid

valve from the VXTC control housing.

The VXTC is designed for the installation in 3/4" NPT black iron or steel piping. For servicing of the

control, the VXTC should be installed with unions and a bypass. The bypass should be construct-

ed so that all water added to the boiler is metered.

POWER THE CONTROL Once the control is plumbed and wired, power the system. Upon initial power up, the control will go through a 10 second self-diagnostic test cycle. During this period various characters will be displayed on the LED screen and the solenoid will power up for approximately one second. This only takes place upon powering the control. DIAGNOSTIC SYMBOLS The Diagnostic LED indicate mode of operation and can be used to troubleshoot programming errors.

DETERMINING PROPER FEED SETTINGS To determine the proper feed setting follow these steps: 1. With the feeder in the “LWCO” position, power-up the system and set the thermostat so there is no call for heat. Open the boiler drain and slowly lower the water level until the boiler control calls for a feed. Stop draining the water and allow the VXTC to raise the water level in the boiler. Check the water level following the feed cycle. 2.
