7.3.10 Other system components
7.3.10.1 Global fault message input
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.
7.3.10.2 Global fault message output
This function must be activated in the "Hydraulics" menu for a
variable output (VO1 or VO2).
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.
7.3.10.3 Timer
Only active if setting "14" (timer) was selected for parameter 05
(direct heating circuit pump output) in the "Hydraulics" menu.
This function controls a consumer according to the current
switching time program of the direct heating circuit.
