Gira KNX 2139 00 Product Documentation page 19

Scope of functions
– Manual operation of outputs independent of the KNX (for instance, construc-
tion site mode) with LED status indicators. Separate status feedback to the
KNX for manual operation. Manual operation can also be disabled via the
KNX. Own cycle time and PWM setting for manually-operated valve outputs.
Central activation of all valve outputs (0% / 100%).
– Behaviour in case of bus voltage failure and bus voltage return as well as after
ETS programming settable for each valve output.
– Various actively transmitting status signals can be delayed globally after bus
voltage return or after an ETS programming operation.
– The parameters of the outputs can be set individually (each valve output pos-
sesses its own parameters) or alternatively like valve output 1.
Room temperature controller
– Up to 12 independent room temperature controllers.
– Individual control of a controller using communication objects.
– Various operating modes can be activated: Comfort, Standby, Night and Frost/
heat protection
– Each operating mode can be assigned its own temperature setpoints (for heat-
ing and/or cooling).
– Configuring the temperature setpoints as relative (derived from basic setpoint)
or absolute (independent setpoint temperatures for each operating mode).
– Comfort extension possible using presence button in Night or Frost/heat pro-
tection mode. Configurable duration of the comfort extension.
– The operating modes are switched over via 1-byte objects according to the
KNX specification.
– Status feedback telegrams can be configured.
– Frost/heat protection switchover via window status or by automatic frost pro-
tection.
– Operating modes "Heating", "Cooling", "Heating and cooling" each with or
without additional level. The temperature setpoints for the additional level are
derived via a configurable level offset from the values of the basic level.
– Various control types can be configured for each heating or cooling level: PI
control (permanent or switching PWM) or 2-point feedback control (switching).
– Control parameter for PI controller (if desired: proportional range, reset time)
and 2-point controller (hysteresis) adjustable.
– Automatic or object oriented switchover between "heating" and "cooling".
– A temporary or permanent setpoint shift for a relative setpoint specification
through communication objects is possible (e.g. via a controller extension).
– Configurable step width of the setpoint shift (0.1 K / 0.5 K).
– Deactivating the feedback control or the additional level possible using separ-
ate 1-bit objects.
