How to quickly heat a room?
The solution is the activation of the "BOOST" function
Activate the "BOOST" function is and set the intensity of operation with parameters P2.3, while the operation time is set with the parameter P2.4. The same can be set using the parameters P3.3 and P3.4 "BOOST" for the second heating circuit. In most cases, it suffices that the desired temperature is increased by 3°C and the operating interval is set to 60 minutes. If the building has poor thermal insulation, a higher room temperature correction should be set, while in case of better isolation a smaller setting is sufficient.
We increase the operation interval for buildings with a greater time delay, e.g. in the case of floor heating. In this case, the controller increases the setting of the desired room temperature by 100% of the setpoint only if the night-time temperature interval was longer than 10 hours.
If the interval is shorter, the room temperature increase is reduced proportionally to 10% which is reached at 1h of the night-time temperature interval. If the night-time temperature interval is less than 1h, the "BOOST" function is not activated. The described operating mode provides another opportunity to fine-tune the operation of Seltron weather-compensated heating controllers. Due to accumulation and additional heat sources, the room temperature in the evening is usually slightly higher than the desired room temperature.
When we have a built-in room sensor, the latter only performs the stand-pipe temperature correction and ensures that the room temperature only minimally deviates from the desired setting. In the case where there is no room sensor a similar effect can be achieved by changing the time program. To do this, insert one or two shorter heating intervals with the night-time temperature in the evening program.
In this way, the desired reduction in room temperature is achieved. Take care that the night-time temperature interval is less than 60 minutes. Otherwise, the "BOOST" function will be activated to compensate for the reduction of room temperature without having the desired effect. The "BOOST" function can also be activated when a room sensor or room unit is connected. This comes in especially handy when the effect of the room sensor correction must be reduced or even switched off completely.
