Carrying out an actuator test
Note
An actuator test can only be carried out when the
boiler is cold.
If the actuator test is carried out for one mixer, all other
connected mixers remain in standard operation. Fol-
lowing the actuator test, the tested mixer reverts to
standard operation after 3 minutes.
The actuators are split into several categories, based
on their application:
■
Boiler actuators
■
Actuators for the corresponding mixer modules
