Earth Ground Connection
The controller has a connection for earth ground. For best results a cold water pipe should be
used with a pipe wiring clamp. If a cold water pipe is not available connect to a suitable
ground connection in the installation.
A minimum 14AWG solid copper wire should be used from the controller's earth connection
point to the clamp on the cold water pipe. If other earth clamps are present at the same
connection point connect the clamp below the existing units.
Figure 3 - Controller Main Earth Ground Connections
The telephone communication dialler contains a separate earth connection. Do not
loop the earth connection from the dialler to the earth of the controller. A separate
connection should be connected to the same earth point.
AC Power
The controller should be supplied by a dedicated electrical power source rated for a minimum
10Amp Load and have a dedicated circuit breaker. Do not use a switch controlled breaker or a
switched electrical point to supply electrical power. Connect the primary of a 16.5VAC,
50/60Hz, 40VA Transformer to the electrical circuit and run the secondary to the AC input on
the controller terminals.
