SYSTEM CIRCULATOR PUMP (SYS PMP)
If a system circulator pump is connected to the Sys Pmp terminal (3) and
N terminal (4), make sure that power to the terminal block is off and install
a jumper between the Power L and the Sys Pmp terminals (1 and 3). Install
a second jumper between the Power N and N terminals (2 and 4). When
power is applied to the Power L and Power N terminals (1 and 2), the system
circulator pump should start. If the circulator pump does not turn on, check
the wiring between the terminal block and circulator pump and refer to any
installation or troubleshooting information supplied with the circulator pump.
If the pump operates properly, disconnect the power and remove the
jumpers.
BOILER
If the boiler is connected to the Boiler terminals (5 and 6), 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 fi re. If the boiler does not
turn on, refer to any installation or troubleshooting information supplied with
the boiler. (The boiler may have a fl ow switch that prevents fi ring until the
boiler 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 respective headers on the control and then pushing the terminal blocks
into the headers. The terminal blocks should snap fi rmly into place.
Install the supplied safety dividers between the unpowered sensor inputs
and the powered 120 VAC or 24 VAC wiring chambers.
Apply power to the control. The operation of the control on power up is
described in section 2.1.
MIXING OR INJECTION VALVE ACTUATOR
If a fl oating action actuating motor circuit is connected to the R Opn, R Cls,
and C terminals (7, 8, and 9), the control's Test Sequence can be used to
check the motor circuit. Once the Test button is pressed, the valve should
move to the fully open position. If the motor closes instead of opening, the
wiring of the actuating motor must be reversed. Next, the actuator should
move the valve to the fully closed position. If it does not, check the wiring
between the terminals and the actuating motor. Refer to any installation or
troubleshooting information supplied with the actuator.
