Boiler Wiring Terminals

External Flow and return sensors (QAD21) are required for Cascade Manager Units only. The sensors must be wired to the terminal detailed below.

These terminals are located on the top left of the boiler frame when viewed from the front.

(These terminals are pre-wired on Standalone FS units.)

Module Controller Mounted Safety Interlock Terminals (X10:03)(Low Voltage<25V) If required each module can be connected to an external safety device. A relay must be used to ensure separation of the voltages generated by each module controller. (X10:03)
