Panasonic V1.00 KNX Room Thermostat
Functional characteristics
Room temperature controller sense the current room temperature and controls the heating and/or cooling. It is also controls Fan coil units. Device has 2 different weekly switching programs which can be programed separately by user. The display is backlighted for easier reading. The Room temperature controller is fitted with push-switches and an LCD to show the current operating modes and values. A separate bus coupling unit is not required. The room temperature controller does not require an auxiliary power supply. The Engineering Software Tool (from ETS3-f) is used to assign the physical address and set the parameters.

The Heating Control parameter page
| Designation | Values | Description |
| Heating controller type | 2 Step
Continuous |
This function allows you to specify the mode of control.
You can select “2-step control” or “Continuous control” |
| 2 Step Parameters | ||
| Heating hysteresis | 0.2K | Set a hysteresis value to ensure that the valve |
| 0.4K | does not constantly switch with each minor | |
| 0.6K | under and overshoot when using 2-step | |
| 0.8K | control of the actuator. | |
| 1.0K | The hysteresis value lies around the setpoint. | |
| 1.2K | For example, if the setpoint is 21 °C and the | |
| 1.4K | hysteresis is 1 K, the room thermostat only | |
| 1.6K | sends an “on” signal at 21.5 °C and an “off” | |
| 1.8K | signal at 20.5 °C. This parameter is only | |
| 2.0K | available if “2-step ” is set as the control type. | |
| Heating invert control value | no
yes |
This parameter is used to adjust the direction of control action of the control value to “de- energised open” or “de-energised closed” valves. |

Professional setting for adapting control response to the room.
Small values cause large changes in control variables, larger values cause finer control variable adjustment. |
| Heating integral reset time | Value from 0 to 250 | Professional setting:
See appendix: Response of the PI controller This time can be adapted to suit particular circumstances. If the heating system is over- dimensioned and therefore too fast, shorter values should be used. Conversely, under-dimensioned heating (slow) benefits from longer integrated times. |
| Heating PWM cyclic time(Min.) | Value from 1 to 60 | An actuation cycle consists of a switch-on and a switch-off
process and forms a PWM period.
Example: Actuating value= 20%, PWM time = 10 min: In an actuating cycle of 10 min, 2min switched on and 8 min switched off (i.e. 20% on/ 80% off). |
| Transmit control value at change of | %1
%2 %3 %4 %5 … %12 %13 %14 %15 |
After how much % change* in the control variable is the new value to be sent. Small values increase control accuracy but also the bus load.
*Change since last transmission |
| Heating transmit control value cyclically | Not cyclically, only at change
every 2 min. every 3 min. every 5 min. every 10 min. every 15 min. every 20 min. every 30 min. every 45 min. every 60 min. |
