| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow boiler and system to heat.
Measure the temperature differential.
Expect a differential of approximately 20°C or less.
Is the differential as expected?
Note:
Differential may be higher on initial start-up, allow boiler to run until return pipe starts to heat or the boiler shuts down before selecting an option. Turning off some radiators may reduce time taken for this test.
