Boiler Demand
If a
Boiler Demand is used, measure the voltage between the Boil Dem
and the
Com Dem terminals (4 and 3). When the Boiler Demand device
calls for heat, you should measure between 20 and 260 V (ac) at the
terminals. When the
Boiler Demand device is off, you should measure
less than 5 V (ac).
DHW Demand
If a
DHW Demand is used, measure the voltage between the Setp /
DHW and the Com Dem terminals (5 and 3). When the DHW Demand
device calls for heat, you should measure between 20 and 260 V (ac)
at the terminals. When the
DHW Demand device is off, you should
measure less than 5 V (ac).
Setpoint Demand
If a
Setpoint Demand is used, measure the voltage between the Setp /
DHW and the Com Dem terminals (5 and 3). When the Setpoint
Demand device calls for heat, you should measure between 20 and
260 V (ac) at the terminals. When the
Setpoint Demand device is off,
you should measure less than 5 V (ac).
Testing the Outputs
Boiler Pump (Boil P1)
If a boiler pump is connected to the
Boil P1 terminal (8), make sure that power to the
terminal block is off and install a jumper between the
Power L and the Boil P1 terminals
(7 and 8). When power is applied to the
Power N and Power L terminals (6 and 7), the
boiler 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 jumper.
DHW Pump OR Valve (DHW Pmp/Vlv)
If a DHW pump or DHW valve is connected to the
DHW Pmp / Vlv terminals (9 and 10),
make sure the power to the pump or valve circuit is off and install a jumper between those
terminals. 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
operate correctly, disconnect the power and remove the jumper.
Mixing Pump (Mix P2)
If a mixing pump is connected to the
Mix P2 terminal (11), make sure that power to the
terminal block is off and install a jumper between the
Power L and the Mix P2 terminals
(7 and 11). When power is applied to the
Power N and Power L terminals (6 and 7), the
mixing 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 jumper.
Boiler
If the boiler is connected to the
Boiler terminals (12 and 13), 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 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 (14 and 16), make sure the power to
the terminal block is off and install a jumper between the
Pwr Mix and Cls / Var terminals (14 and 16). 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.
