2. Directly from a remote electrical control (such
as a turbine speed control or PLC). This contact
must correspond and signal that air is flowing
through the heater.
This electrical circuit must be connected using a
minimum 1 amp dry contact relay (such as PLC
contact). This can be completed by the following:
1. Remove the present wire from TB8-1.
2. Using a wire nut, connect the wire removed in
step 1 to a longer wire and route to one side of the
remote contact.
3. Run a wire from the other side of the remote
contact back to TB8-1.
4. Add pressure switch changes, A1.
When the remote contact is closed, the air heater
will turn on.
