Test The Outputs
Primary Pump (Prim P1)
If a primary pump is connected to the Prim P1 terminal (8), make sure that power
to the terminal block is off and install a jumper between the Power L and Prim P1
terminals (7 and 8). When power is applied to the Power L and Power N terminals
(7 and 6), the primary 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 trouble-
shooting information supplied with the pump. If the pump operates properly, discon-
nect the power and remove the jumper.
Boiler System Pump (Boil Sys Pmp P2)
If a boiler system pump is connected to the Boil Sys Pmp P2 terminals (9 and 10),
make sure power to the pump circuit is off and install a jumper between terminals (9
and 10). When the pump circuit is powered up, the boiler system pump should start.
If the pump does not start, 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 jumper.
Mixing System Pump (Mix Sys Pmp P3)
If a mixing system pump is connected to the Mix Sys Pmp P3 terminals (11 and
12), make sure power to the pump circuit is off and install a jumper between termi-
nals (11 and 12). When the pump circuit is powered up, the mixing system pump
should start. If the pump does not start, 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
jumper.
DHW Pump OR Valve (DHW Pmp/Vlv)
If a DHW pump or DHW valve is connected to the DHW Pmp / Vlv terminals (13
and 14), make sure power to the pump or valve circuit is off and install a jumper
between terminals (13 and 14). When the DHW circuit is powered up, the DHW
pump should turn on or the DHW valve should open completely.
If the DHW pump
or valve fails to operate, check the wiring between the terminals and the pump
or valve and refer to any installation or troubleshooting information supplied
with these devices. If the DHW pump or valve operates properly, disconnect the
power and remove the jumper.
Boiler
If the boiler is connected to the Boiler terminals (15 and 16), 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 primary pump (P1) is running). If the
boiler operates properly, disconnect the power and remove the jumper.
Variable Speed Injection Pump
If a variable speed injection pump circuit is connected to the Pwr Mix and Cls / Var terminals (17 and 19), make sure the power
to the terminal block is off and install a jumper between the Pwr Mix and Cls / Var terminals (17 and 19). 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 jumper.
Mixing Valve Actuator
If a floating action actuating motor circuit is connected to the Pwr Mix, Opn and Cls / Var terminals (17, 18 and 19), make sure
power to the motor circuit is off and install a jumper between the Pwr Mix and Opn terminals (17 and 18). 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 (17 and 19). When the circuit is powered
up, the actuator 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.
