s Button
The user will not normally need to use this button. It is used by the service technician to enable measurement of
flue emissions even without heat requirement being present.
NOTE: This function will not be available if the MICROMAT EC and the heating system have reached their maximum
temperatures.
If the Engineers button is pressed once then the MICROMAT EC operates with half power. The display shows [Flue
Emissi]. If the Engineers button is not pressed again within 10 minutes the MICROMAT EC will switch back to
automatic operation after this period. Pressing the button again when [Flue-Emissi] is displayed brings [10min Low]
onto the display. In this condition the power output of the boiler can be adjusted using the ‘+’ and ‘-’ keys
Pressing the ‘-’ key will reduce the power & pressing the ‘+’ key will increase power.
Pressing the Engineers button again while [10 min. low] is shown in the display switches the MICROMAT EC back
to automatic operation. After 10 minutes partial output the MICROMAT EC will return to automatic operation
