6.4 Direct Mode
The following figure shows the activation of the direct mode:
Figure 54: Direct Mode
The a of o trolli g the dire t ode is set dire tl i the e u „Ge eral setti gs . Three differe t
ways of controlling the direct mode are available.
6.4.1 binary coded
At the binary coded controlling, the bits are evaluated combined:
Value - Bit 1 Value - Bit 0 Step
0 0 0
1 1
1 0 2
1 1 3
Table 54: Direct Mode - binary coded
The following communication objects are available:
Number Name Length Usage
9 Bit 0 1 Bit Activation/Deactivation of Bit 0
10 Bit 1 1 Bit Activation/Deactivation of Bit 1
Table 55: Communication objects - Direct mode binary coded
6.4.2 Step switch
At the step switch, every step is controlled by a separate communication object. If a communication
object receives a logical 1 at one communication object, this step will be switched on and all others
steps will be switched off. A logical 0 has no effect.
The following communication objects are available:
Number Name Length Usage
9 Step 0 1 Bit Switching the FanCoil off
10 Step 1 1 Bit Switching step 1 on
11 Step 2 1 Bit Switching step 2 on
12 Step 3 1 Bit Switching step 3 on
Table 56: Communication object - Direct mode step switch
6.4.3 - 1 Bit Up/Down
At the dire t ode ia Bit Up/Do , the step is redu ed/i reased at re ei i g a / . A logi al
switches the FanCoil one step up and a logical 0 one step down.
The following communication objects are available:
Number Name Length Usage
9 Up/Down 1 Bit 0 = switching one step down
1 = switching one step up
