Mend Firebird 90 Combi Central Water Pump

how can I fix my central heating firebird 90 combi?

hot water working ok but not heating radiators, pump is working ok as new but not firing up for central heating. Relay switch is also ok. What else can I check?

The controller sends mains voltage to operate the relay which switches on the pump. When the central heating is active, check that you are getting 240v ac at the relay coil. If you are but the relay is not activated, then the relay is faulty and should be replaced. If there is no voltage at the coil then the controller is faulty and needs to be replaced
