Test The Outputs
System Pump (Sys Pmp)
If a system pump is connected to the
Sys Pmp terminal (5), make
sure that power to the terminal block is off, and install a jumper
between the
Power L and the Sys Pmp terminals (3 and 5). Install
a second jumper between
Power N and N terminals (4 and 6). When
power is applied to the
Power L and Power N terminals (3 and 4),
the system pump should start. If the pump does not turn on, check
the wiring between the terminal block and pump, and refer to any
installation or troubleshooting information supplied with the pump.
If the pump operates properly, disconnect the power and remove
the jumpers.
Variable Speed Injection Pump (
Var Pmp
)
If a variable speed injection pump is connected to the
Var Pmp terminal (7), make sure that power to the terminal block is off, and
install a jumper between the
Power L and the Var Pmp terminals (3 and 7). Install a second jumper between Power N and N
terminals (4 and 8). When the variable speed pump circuit is powered up, the variable speed pump should operate at full speed.
If the pump does not operate, check the wiring between the terminal block and the pump, and refer to any installation or
troubleshooting information supplied with the pump. If the pump operates properly, disconnect the power and remove the jumpers.
Boiler
If the boiler circuit is connected to the
Boiler terminals (9 and 10), make sure power to the boiler circuit is off, and install a jumper
between the terminals. When the boiler circuit is powered up, the boiler should fire. If the boiler does not turn on, refer to any
installation or troubleshooting information supplied with the boiler. (The boiler may have a flow switch that prevents firing until the
boiler loop pump is running). If the boiler operates properly, disconnect the power and remove the jumper.
Connecting The Control
Make sure all power to the devices and terminal blocks is off, and remove any
remaining jumpers from the terminals.
Reconnect the terminal blocks to the control by carefully aligning them with their re-
spective headers on the control, and then pushing the terminal blocks into the headers.
The terminal blocks should snap firmly into place.
Install the supplied safety dividers between the unpowered sensor inputs and the pow-
ered 120 V (ac) or 24 V (ac) wiring chambers.
Apply power to the control. The operation of the control on power up is described in the
Sequence of Operation section of this brochure.
