Valve control
To control valves, five operating modes are available:
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Control | On/Off (default) Limit values PWM PI Temperature control 2-points Temperature control | Depending on the control mode, specific parameters are displayed. |
| Type | Normally closed (default) Normally open | In case of normally open valve, the output state is inverted. |
| Valve protection | Disabled (default) Enabled | When enabled, the valve is automatically activated for 5 minutes every 24h as a protection for long durations without activation. |
| Send output status | Disabled (default) Enabled | When enabled, the valve output status is send using a dedicated status object. |
On/off control
On/Off control is used to control the valve directly using the corresponding group object. The output follows the state of the input command.
Communication Objects
| NR | NAME | FUNCTION | SIZE | FLAGS | TYPE |

| 1 | Block | On/Off | 1 bit | CRW | DPT_Enable |
| 3 | Valve On/Off | On/Off | 1 bit | CW | DPT_Switch |
| 5 | State | On/Off | 1 bit | CRT | DPT_Switch |
Limit values control
The valve control is performed by percentages. When this option is enabled, it is necessary to configure 2 parameters that define the hysteresis value.
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Upper limit (%) | From 0 to 100% | The upper limit determines when the valve is activated (it must be greater than 0). |
| Lower limit (%) | From 0 to 100% | The lower limit determines when the valve is deactivated (value must be smaller than the upper limit). |

| 7 | Control value | Percent | 1 byte | CW | DPT_Percent |
PWM control
The PWM cycle time is used for calculating the on and off pulses of the control value. This calculation
is based on the incoming control value. A PWM cycle includes the whole time which elapses from
one switch-on pulse to the next.
| PARAMETER | VALUES | DESCRIPTION |
|---|
| PWM cycle (min) | From 1 to 255 min. | Defines the cycle period for the PWM control. |
| Upper limit (%) | From 0 to 100% | The upper limit of the input command value. The received value will be limited by this setting. |
| Lower limit (%) | From 0 to 100% | The lower limit of the input command value. The received value will be limited by this setting. |

PI temperature control
The PI temperature controller allows to directly control the valve based on the room temperature. The temperature controller can be used for heating, cooling or combined heating and cooling.
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Scene control: Scene 1 Scene 2 Scene 3 Scene 4 | 0 (default) 1 to 64 | When set to 0 the channel will ignore corresponding scene. When set to another value, the channel will respond to this scene number. Channel state can be store using the scene group object for further recall. |
| PWM cycle (min) | From 1 to 255 min. | Defines the cycle period for the PWM output of the control. |
| Proportional band | 4 (default) 1 – 20 | Proportional band of the PI controller |
| Reset time | 120 min. (default) 15 – 240 min | Reset time of the PI controller |
| Minimum output | 0% (default) 0 – 100 % | Minimum output of the controller |
| Maximum output | 100% (default) 0 – 100 % | Maximum output of the controller |
| Heating/Cooling mode | Cooling Heating (default) Cooling/Heating group object | Operating mode of the controller. When choosing the mode from the group object, a general “Heating/Cooling switch” object is used to change the operating mode of all temperature controllers. |
| Comfort setpoint | 21°C (default) 14-25°C | Temperature setpoint in comfort mode |
| Standby reduction for heating | 3°C (default) 0-10°C | Temperature setpoint reduction in standby mode for heating |
| Night reduction for heating | 1.5°C (default) 0-10°C | Temperature setpoint reduction in night mode for heating |
| Standby increase for cooling | 3°C (default) 0-10°C | Temperature setpoint increase in standby mode for cooling |
| Night increase for cooling | 1.5°C (default) 0-10°C | Temperature setpoint increase in night mode for cooling |
Setting the proportional band and reset time depending on the type of installation:
- Warm water heating: (4 / 120min)
- Underfloor heating: (4 / 150min)
- Split Unit: (4 / 60min)

2-points temperature control
The 2-points temperature controller allows to directly control the valve based on the room temperature. The temperature controller can be used for heating, cooling or combined heating and cooling.
| PARAMETER | VALUES | DESCRIPTION |
|---|
| Scene control: Scene 1 Scene 2 Scene 3 Scene 4 | 0 (default) 1 to 64 | When set to 0 the channel will ignore corresponding scene. When set to another value, the channel will respond to this scene number. Channel state can be store using the scene group object for further recall. |
| Switching hysteresis | 0.5°C (default) 0-10°C | The switching hystereris defines the switch on and off triggers for the channel output. The channel is switched on if the temperature is lower than the setpoint - hysteresis and is is switched off if the temperature is greater or equal to the setpoint. |
| Heating/Cooling mode | Cooling Heating (default) Cooling/Heating group object | Operating mode of the controller. When choosing the mode from the group object, a general “Heating/Cooling switch” object is used to change the operating mode of all temperature controllers. |
