4.2.4.3.8 Disable functions of the room temperature controller
Certain operation conditions may require the deactivation of the room temperature control. For
example, the controller can be switched-off during the dew point mode of a cooling system or
during maintenance work on the heating or cooling system. The "Via object" setting in the
"Switch off controller (dew point operation)" parameter in the "Room temperature control ->
Controller functionality" parameter node enables the 1-bit "Disable controller" object. In addition,
the controller disable function can be switched off when set to "No".
In case a "1" telegram is received via the enabled disable object, the room temperature control
will be completely deactivated. In this case, all command values are equal "0" (wait 30 s for
update interval of the command values). The controller, however, can be operated in this case.
The additional stage can be separately disabled when in two-stage heating or cooling mode.
When set to "Yes", the "Additional level disabling object" parameter in the "Room temperature
control -> Controller general" parameter node will enable the
1 bit "Disable additional level" object. In addition, the disable function of the additional level can
be switched off when set to "No". In case a "1" telegram is received via the enabled disable
object, the room temperature control is completely deactivated by the additional level. The
command value of the additional level is "0" while the basic level continues to operate.
i
The controller has no function in dew point operation. The building functions to be
controlled are in a critical state, which must be monitored by the building system.
i
A disable is always deleted after a reset (return of bus voltage, ETS programming
operation).
