Parameter settings

Interface KNX B8-TH

• Version: 24.08.2016 • Technical changes and errors excepted.

For an adequate regulation of the indoor temperature, comfort, standby, eco and build-
ing protection modes may be used.

Comfort

when present,

Standby

when absent,

Eco

as a night-time mode and

Frost / heat protection

(building protection) e.g. when the window is open.

The settings for the temperature control include the set point temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).

The

mode

may be switched with

two 8 bit objects

of different priority. Objects

„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
1 = Comfort
2 = Standby
3 = Eco
4 = Building protection

Alternatively, you can use

three objects

, with one object switching between eco and

standby mode and the two others are used to activate comfort mode or frost/heat pro-
tection mode. The comfort object then blocks the eco/standby object, and frost/heat
protection objects have the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"

Select the

mode to be activated after reset

(e.g. power failure, reset of the line via

the bus). (Default).
Then configure a temperature control

block

by the blocking object.

Specify when the current

control variables

are to be

sent

to the bus. Periodic trans-

mission is safer if a message does not reach a recipient. You may also set up periodical
monitoring by the actuator with this setting.

Switch mode via

• two 8-bit objects (HVAC modes)
• three 1-bit objects

Mode after reset

• Comfort
• Standby
• Eco
• Building protection

Behaviour of the blocking object with value

• 1 = Block | 0 = release
• 0 = block | 1 = release

Value of the blocking object after reset

0 • 1

Transmit control variable

• on change
• on change and periodically

from change of (in % absolute)
