The DPT RHCC Status object is an additional 2 Byte status object with additional status messages. If
more than one testify is valid, also here the values will be added in the same way as at the HVAC
object.
The following chart shows the hex values for the single messages:
Bit DPT RHCC Status Hex-Value
0 Error Sensor 1=Error 0x01
8 Heating/Cooling 0=Cooling/1=Heating 0x100
13 Frost alarm 1=Frost alarm 0x2000
14 Heat alarm 1=Heat alarm 0x4000
Table 21: Hex-Values DPT RHCC Status
The Controller reacts always to the value, which was sent last. If you switched the operating mode
last via 1 Bit, the controller will react to the changeover by 1 Bit. If you switched the operating mode
last via 1 Byte, the controller will react to the changeover by 1 Byte.
The communication objects for the mode selection are shown at the following chart. The first 3
communication objects are for the 1 Bit changeover, the last 3 objects are for the changeover via 1
Byte:
Number Name Length Usage
10 Mode Comfort 1 Bit Activation of the mode comfort
11 Mode Night 1 Bit Activation of the mode night
12 Mode Frost/Heat protection 1 Bit Activation of the mode Frost/ Heat protection
22 DPT_HVAC Status 1 Byte Visualization of the chosen operating mode
25 DPT_RHCC Status 2 Byte Visualization measuring/ status of the controller
26 mode selection 1 Byte Selection of the operating mode
