Wiring the VTC-1D
1.
Set the voltage switch
A
to the correct position for
the line voltage used.
2.
Set jumper
E
to the correct position for the
temperature units (Fahrenheit or Celsius) you want
to use.
3.
Connect the incoming power and load wires as
shown in the diagram.
Connecting the temperature probe
Follow the guidelines below and connect the
temperature probe as shown in the diagram.
Do not run the probe cable in the same conduit as
AC power cables
Do not run the sensor cable beside AC power
cables or near electrical equipment.
When crossing other cables or power lines, cross
them at a 90 degree angle.
Using four-zone averaging
The VTC-1D can monitor the temperature in four
different zones. The control takes an average of the four
temperatures and operates according to the average
temperature.
To use four-zone averaging, you must connect four
temperature sensors to the unit. Connect the probes as
shown to the right.
Extending probe cables
You can extend temperature probe cables to lengths of up to 500 feet. Follow the temperature probe
guidelines and the guidelines below when extending cables.
Use two-wire 18 AWG jacketed cable. Phason recommends Belden # 9408, Alpha # 5052, or an
equivalent. Extension cable is also available from Phason. For more information, contact your dealer or
Phason.
If the unit operates erratically with the extended probe, run the cable along a different path or shorten it.
