HRV Timer Settings

Vernon Manufacturing

Automatic Water Salesman

Your Automatic Water Salesman will accept 250 inputs (\$62.50), so in a practical sense, it will accept “any” amount.

This timer contains 2 sets of switches in one unit of 10 switches.  To move the proper switches to the “ON” position, use a pointed object such as a retracted ballpoint pen.  DO NOT USE A PENCIL.  The switches turn “ON” to the right.  Remember:  1 quarter = 1 input.  \$1.00 = 4 inputs.  \$20.00 = 80 inputs.

TIMER SETTINGS:  AMOUNT TO BE SOLD

The top 7 switches (Time per Coin) determine the length of time the water will run for EACH COIN inserted.  One second is minimum adjustment and accuracy.  Determine the length of time you want the valve to be open.  Turn ON the switches that add up to that amount of time.

A 2” line at a pressure of 50 psi, will flow at approximately 2 gallons per second.  This will vary with valve size, length of run, friction loss, etc.  All examples are based on these parameters.  Larger valves and/or higher pressure = less time.   Lower pressure = more time.

Example 1:  Water rate of \$1.00 per 1000 gallons.  1000 ÷ 4 quarters = 250 gallons for 25¢.  Start

with switches 64; 32; 16; 8; 4; 2 ON (126 seconds).  All other switches  OFF.

Example 2:  Water rate of \$5.00 per 1000 gallons.  1000 ÷ 20 quarters = 50 gallons for 25¢.  Start

with switches 16; 8; 2 ON (26 seconds).  All other switches OFF.

Example 3:  Water rate of \$10.00 per 1000 gallons.  1000 ÷ 40 quarters = 25 gallons for 25¢.  Start

with switches 8; 4; and 1 ON (13 seconds).  All other switches OFF.

TIMER SETTINGS:  MINIMUM SALE

The bottom 3 switches (Coins to Start) determine how many (inputs) must be counted before the machine starts.  Normally this is 1.  If a minimum sale is desired, up to 7 inputs (\$1.75) can be programmed.  Adding the switches together determines the amount.  At least one switch MUST be turned on.

Example 1: 50¢ minimum.  Turn ON switch 2 (2 coins).  1 and 4 OFF.

Example 2:  75¢ minimum.  Turn ON switches 1 and 2 (3 coins).  Switch 4 OFF.

These settings can be readjusted at any time as your water rates go up or you wish to change the minimum sale.  Over the years, we have found the average cost of water to be anywhere from \$3.00 to \$10.00 per 1000 gallons.  Your city's water pressure and selling rates will determine the amount of time needed.  Please call if you need help.
