Remote Fault Indication
The MICROMAT EC boiler includes a built in fault alarm relay with volt free
contacts for interface with, if required a remote alarm indicator.
The volt free contacts within the boiler control panel will close in the event
that the boiler goes to a fault resulting in boiler lockout. The volt free contacts
indicate “common alarm” upon closing. The actual fault description will be
displayed upon the LCD screen of the boiler.
Connection to the volt free contacts is made via an alarm plug and lead
assembly available from RVR Ltd.
The alarm plug and lead connects to socket x9 located in the lower area of
the boiler control panel.
The MICROMAT EC boiler should be expertly commissioned by a competent engineer who will need, in addition
to standard hand tools, a U tube manometer and a combustion analyser.
Before attempting to set the MICROMAT EC boiler to work, the following check list must be worked through.
