The condensate pump must be equipped with an over flow switch to prevent the appliance from
running should a failure occur. The over flow switch must be wired to the Remote Interlock of the
AERCO boiler/water heater I/O Box for KC1000, Innovation, and Benchmark units (see Figure 8);
or, for Modulex units, on Pins 3 and 4 of Connector I on Modulex E8 controller (see Figure 9).
NOTE:
For Modulex boilers, an over flow switch may only be utilized in Indoor/Outdoor Reset and
Constant Set Point modes of operation.
It cannot be utilized in 0 to 10 Volt Remote Set Point mode and when a BMS II is used.
To utilize an overflow switch, set the Modulex boiler to Standby mode (
). To set the boiler
to Standby mode, close the swing-down front panel door of the E8 and turn the wheel counter-
clockwise until the Standby symbol (
) is displayed. With pins 3 and 4 closed, the Standby
symbol, and others in the display, will be blinking. This indicates that the boiler is enabled.
When the connection is broken between pins 3 and 4, the Standby symbol, and others in the
display, will stop blinking indicating that the boiler is disabled. Closing/breaking pins 3 and 4
not only start/stops the boiler but also start/stops other pumps (boiler water pumps) wired to
the Modulex boiler.
