A 150-1 Operation The One Stage Setpoint Control 150 regulates the temperature of the slab by turning the injection pump on and off in response to temperature changes at the slab sensor. Note: For optimum control, the supply temperature from the boiler should be constant. This will allow the system to be balanced so that the supply fluid to the slab is just hot enough to maintain the slab temperature at design conditions.
