3.

Remove the front panel of the BUH kit.

4.

Check circuit breaker F1B/; reset circuit breaker F1B if it has tripped.

5.

Check thermal protector backup heater Q1L; reset thermal protector backup heater Q1L if it has tripped.

4.1.1. Overall power circuit check

1.

Power the Daikin Altherma Monobloc CA.

2.

Activate “Installer level” on the user interface, refer to “Installer Level Settings” in the Installer Reference Guide to access the
most used commands.

3.

Select Actuator test run A.7.4.

-

Activate BUH step 1.

-

Activate BUH step 2.

4.

Check the status of backup heater step 1/2 in Menu 6.5 (Actuators); status must be:

-

6.5.3 BUH step 1 = ON

-

6.5.4 BUH step 2 = ON

5.

Measure the voltage:

-

Check if field installed circuit breaker Q1D1 tripped.

-

Check if the overcurrent fuse F1B or F2B of the backup heater tripped.

-

Check the thermal protector Q1L of the backup heater.

-

Check contactors K1M, K2M & K5M (if used).

- Example:

Measure the voltages between connectors K1M 2-4/4-6/6-2 before K1M.
All voltages must be /- 10% (3 phase) or /- 10% (1 phase).

-

Between K1M 2 - 4, K1M 4 - 6 and K1M 2 - 6; all voltages must be 400 VAC ±10%.

-

If voltages are OK on pins 2 - 4 - 6 but not on pins 1 - 3 - 5, replace K1M.

I

NFORMATION

If F1B or Q1L trip again, it is required to determine the root cause of the problem because something is overloading the
electrical circuit or creating a short circuit.

Electrical check

I

NFORMATION

If 1 or more checks fail, replace the backup heater.
