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.
