7.3.10.1Global fault message input

Function Activating this function causes the corresponding input to act as a switching contact. With the contact closed (short-circuited), the fault message input is treated as an additional fault in the control system. Intruding fault messages can thus be forwarded via the data bus or taken into account via an additional fault message output.

Up to three different fault messages can intrude via variable inputs.

7.3.10.2Global fault message output

NOTE This function must be activated in the "Hydraulics" menu for a variable output (VO1 or VO2).

Function The function becomes active on detection of fault messages of any kind. It serves as a global fault message output for connecting optical or acoustic alarm signal devices.

7.3.10.3Timer

NOTE Only active if setting "14" (timer) was selected for parameter 05 (direct heating circuit pump output) in the "Hydraulics" menu.

Function This function controls a consumer according to the current switching time program of the direct heating circuit.
