AQUASTAT SWITCHING ACTION WITHIN

L8148A CONTROLS

The switching action in the L8148A control has one set-

ting, the high limit. The switching relay is controlled by the

low voltage room thermostat. On a call for heat, the relay

contacts make to complete the line voltage circulator circuit

and also the burner circuit if the boiler water temperature is

below the high limit setting. The high limit switch shuts off

the burner if boiler water temperature exceeds the high limit

setting.

Set the indicator at the desired shut-off temperature.
