Variable Speed Injection Pump (Storage)
If the storage feature is used in the control, the two variable speed injection pumps must be wired as shown in the wiring section.
To test that the wiring is done correctly, make sure the power to the terminal block is off. Install a jumper between the
Pwr Mix and
Cls / Var terminals (14 and 16). When the variable speed pump circuit is powered up, the boiler’s variable speed pump should
operate at full speed. If the pump does not operate, check the wiring between the terminal block and the pump. Refer to any
installation or troubleshooting information supplied with the pump. If the pump operates properly, disconnect the power.
With the first jumper still in place, insert a second jumper between the
Pwr Mix and Opn terminals (14 and 15). When the variable
speed pump circuit is powered up, the switching relay should energize and the storage tank’s variable speed pump should operate
at full speed. If the relay does not energize, check the wiring between the terminal block and the relay. If the storage tank’s injection
pump does not operate, check the wiring between the terminal block and the pump. Refer to any installation or troubleshooting
information supplied with the pump. If the pump and relay operate properly, disconnect the power and remove both jumpers.
Mixing Valve Actuator
If a floating action actuating motor circuit is connected to the
Pwr Mix, Opn, and Cls / Var terminals (14, 15, and 16), make sure
power to the motor circuit is off and install a jumper between the
Pwr Mix and Opn terminals (14 and 15). When the circuit is powered
up, the actuator should move in the opening direction. If it does not, check the wiring between the terminals and the actuating motor.
Refer to any installation or troubleshooting information supplied with the motor. If the motor closes instead of opening, the wiring
of the actuating motor must be reversed. If the valve opens correctly, turn off the power to the circuit and remove the jumper. Install
a jumper between the
Pwr Mix and Cls / Var terminals (14 and 16). When the circuit is powered up, the valve should move in the
closing direction. If it does not, check the wiring between the terminals and the actuating motor. Refer to any installation or
troubleshooting information supplied with the motor. If the motor closes correctly, turn off the power to the circuit 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 firmly into place.
Install the supplied safety dividers between the unpowered sensor inputs and the powered
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.
