urgently and needs longer until the necessary control variable for the setpoint value
deviation is reached.
You should set the time appropriate for the humidification/dehumidification system at
this point (note manufacturer instructions).
Now specify, what should be sent when the control is blocked.
On release, the control variable follows the rule again.
5.9.
Dewpoint measurement
The settings for the "dewpoint reading" and other air humidity settings are only shown
if the circuit board sensor input has been set to "temperature and humidity sensor" in
the "General settings".
The
Interface KNX B8-TH
calculates the dewpoint temperature and outputs the val-
ue to the bus.
Set which temperature sensor is to be used for dewpoint calculation. Then set the send
pattern.
Activate monitoring of the coolant temperature if required. The menus for the further
setting of the monitoring are then displayed.
5.9.1. Coolant temperature monitoring
A threshold value can be set for the temperature of the coolant, which is based on the
current dewpoint temperature (offset/deviation). The switching output of the coolant
temperature monitoring system can provide a warning prior to any build-up of conden-
sation in the system, and/or activate appropriate countermeasures.
