Object description
2-byte object for transmission of the actual temperature (room
temperature) as measured and varied by a controller or a controller
extension.
(possible range of values: -99.9 °C ... +99.9 °C /
Measuring range of internal temperature sensor:
0 °C ... + 40 °C (1 %)
2-byte object for connection of an external room temperature sensor
or a controller extension (via "actual temperature" object).
(possible range of values: -99.9 °C ... +99.9 °C)
2-byte object for external preset of basic setpoint.
Depending on heating/cooling, the possible range of values is limited
by the parameterized frost protection and/or heat protection
temperature. The received value is mathematically rounded off to
half °C!
1-byte object for switch-over of the controller's operating modes acc.
to KONNEX.
1-bit object for switch-over into the "Comfort" operating mode.
1-bit object for switch-over into the "Standby" operating mode.
1-bit object for switch-over into the "Night" operating mode.
mode.
1-byte object for superordinated forced control of the controller's
operating modes acc. to KONNEX.
1-bit object (bi-directional) which transmits the status of the presence
key to the bus after pressing or which can be used for connection of
a presence detector.
(presence detected = "1", presence not detected = "0")
1-bit object for the connection of window contacts.
(window open = "1", window closed = "0")
1-bit object for switching over between control options "heating" and
"cooling, if not done by the controller automatically
(object value 1: heating; object value 0: cooling).
In case of automatic switch-over the active control option can be
transmitted (parameter-dependent).
1-byte object for general status feedback
1-bit object for individual status feedback of parameterizable
functions of the controller (frost alarm, heating/cooling, comfort
mode, night mode, standby mode, controller disabled, controller
inactive, frost/heat protection).
