Parameters
7.6.2

Basic load active when controller off

Options:
This parameter is used to specify whether the basic load is to be active if the controller has been switched
off via the Request On/Off (master) group object.
•
no: The basic load is also switched off if the controller is switched off.
•
yes: The basic load remains active even if the controller is switched off.
7.6.3

Send inactive control values cyclically

This parameter is enabled if the controller has been parameterized both for heating and for cooling.
For this purpose, Deactivated must not be selected for the parameters Basic-stage heating and Basic-
stage cooling in the Application parameters parameter window.
Options:
The parameter is used to influence the behavior on sending the controller control value output.
This parameter can be used to specify whether the control values for the type of operation not currently
active (heating or cooling) are to be sent or not.
This setting is necessary for systems that have only one control value input for heating and cooling.
In this situation, both output objects for the control value (Status Control value Basic-stage heating and
Status Control value Basic-stage cooling) must be linked to the same input object.
The cyclic sending of both control values in this situation means that the active and inactive value
continuously overwrite each other. To prevent this action from arising, the cyclic sending of the inactive
control value can be inhibited.
