Fault Finding Tests

Fault Finding Tests 1 – 3
Test 1 – Single Element Models
Using a multimeter set on the AC
voltage scale, measure between the
Active terminal 'A' and the Neutral
terminal 'N' on the terminal block.
Normal voltage is 240 Volts AC.
Using a multimeter set on the
resistance scale, measure between
the thermostat terminals marked '3'
and '4' (bottom thermostat on twin
element models).
Normal resistance is less than 1 ohm when the
ECO contacts are closed.

Test 2
Test 1 – Twin Element Models
Using a multimeter set on the AC voltage
scale, measure between the off peak
Active terminal 'A1' and the Neutral
terminal 'N' on the terminal block. Then
measure between the boost Active terminal 'A2'
and the Neutral terminal 'N' on the terminal block.
The following results should be obtained:
Active 'A1' to Neutral 'N' – 240 Volts AC.
Active 'A2' to Neutral 'N' – 240 Volts AC.
Test 3
Using a multimeter set on the
resistance scale, measure between
the thermostat terminals marked '1'
and '2' (bottom thermostat on twin element
models).
Normal resistance is less than 1 ohm when the
thermostat contacts are closed.
