Testing the Control

The Boiler Control 260 has a built-in test routine which is used to test
the main control functions. The 260 continually monitors the sensors,
and displays an error message whenever a fault is found. See the
following pages for a list of the 260’s error messages and possible
causes. When the

Test button is pressed, the test light is turned on.

The individual outputs and relays are tested in the following test
sequence.

TEST SEQUENCE

Each step in the test sequence lasts 10 seconds.

During the test routine, the test sequence is paused by pressing the

Test button. Only if there is a boiler demand can the control be

paused in a step. If the

Test button is not pressed again for 5 minutes while the test sequence is paused, the control exits the entire

test routine. If the test sequence is paused, the

Test button can be pressed again to advance to the next step. This can also be used

to rapidly advance through the test sequence. To reach the desired step, repeatedly press and release the

Test button until the

appropriate device and segment in the display turn on.

Step 1

- The boiler pump (

Boil P1) is turned on for 10 seconds.

Step 2

- The

Boiler contact is turned on for 10 seconds. After 10 seconds, the Boiler and Boil P1 contacts are shut off.

Step 3

- If a DHW pump is selected as the DHW device, the

DHW Pmp / Vlv contact is turned on for 10 seconds and is then shut

off.

- If a DHW valve is selected as the DHW device, the

DHW Pmp / Vlv and Boil P1 contacts are turned on for 10 seconds and

then shut off.

Note: This step can only be paused if a DHW demand is present.

Step 4

- After the test sequence is completed, the control resumes its normal operation.
