NOTES:
1. For master/member systems depress the dip switches J21 and J23 to the “on” position. For the “on” position
press the switch down and in towards the board. This needs to be done on the master and the last member
to terminate the communication network. For all other member boilers the dip switches will remain in the off
position.
Dip switches J3 and J6 need to be placed in the on position to terminate a modbus communication network
when used.
2. 0-10V signals can be used in place of 4-20mA input by changing the position of the jumper “JP3”. This jumper
is located at the inboard end of the communication PCB.
3. Terminal 7 on J12B is the wet prove “sense” terminal. Terminal 8 on J12B is the wet prove “hot” terminal.
