Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Turn Hot Water Tap On
Remove connector X100 (blue) from the PCB and make safe, connect a wire link between the connections
| WARNING! Mains voltage is expected during test, follow TOPs P4 live testing procedure |
Observation:
Is a DHW demand now recognised?
Note:
1. If a DHW demand is recognised with X100 (blue) removed from the PCB and linked out, the condensate connector MUST be refitted after this test and the fault with the condensate pump MUST be rectified as it is not acceptable to leave X100 disconnected.
2. If a DHW demand is still not recognised with X100 (blue) removed from the PCB and linked out, the condensate connector MUST be refitted after this test before continuing.
