Set Appliance State:
CH Demand
The temperature clamp should already be on the flow pipe of the primary heat exchanger from the previous test, It is not possible to connect a clamp to the return, so a temperature probe will need to be placed on the return pipe of the primary heat exchanger
Note.
Ensure a good connection is made with the
flow & return pipes or misdiagnosis will occur

| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow the appliance to run for central heating and the system to heat up.
Measure the temperature differential across the flow and return pipes.
Expect a temperature differential of approximately 20°C or less.
