The heating characteristic in the controller defines the flow temperature set point as a function of the outdoor temperature (see Fig. 16-3). The out- door temperature required for outdoor-temperature-compensated control can either be mea- sured at an outdoor sensor or received over the 0 to 10 V input. °...

Page 119: Gradient Characteristic
Appendix A (configuration instructions) 16.2.1.2 Gradient characteristic Basically, the following rule applies: a decrease in the outdoor temperature causes the flow temperature to increase in order to keep the room temperature constant. By varying the 'Gra- dient' and 'Level' parameters, you can adapt the characteristic to your individual require- ments: The gradient needs to be increased if the room temperature °C drops when it is cold outside.
Page 120 Appendix A (configuration instructions) Outside the times-of-use, reduced set points are used for control: the reduced flow set point is calculated as the difference between the adjusted values for 'Day set point' (rated room tem- perature) and 'Night set point' (reduced room temperature). The 'Max. flow temperature' and 'Min. flow temperature' parameters mark the upper and lower limits of the flow temperature. A separate gradient characteristic can be selected for the limitation of the return flow tem- perature. Examples for adjusting the characteristic − Old building, radiator design 90/70: Gradient approx. 1.8 − New building, radiator design 70/55: Gradient approx. 1.4 − New building, radiator design 55/45: Gradient approx.

Page 123: Underfloor Heating/Drying Of Jointless Floors
Appendix A (configuration instructions) 16.2.3 Underfloor heating/drying of jointless floors Using function block setting CO1, 2 -> F05 - 1, the respective heating circuit is configured as an underfloor heating circuit. In doing so, the controller at first only limits the value ranges of the heating characteristic gradient and the maximum flow temperature in PA1, 2 parameter levels: − Value range of the gradient: 0.2 to 1.0 − Value range of the maximum flow temperature: 5 to 50 °C Furthermore, it is possible to set a Boost between 0.0 to 50.0 °C, which is additionally taken into account when there is a heat demand for the underfloor heating circuit of an upstream control circuit. The Drying of jointless floors function can be activated afterwards. The func- tion block parameters (starting with the 'Start temperature') determine the drying process: the first heating up phase starts at the entered 'Start temperature', which has a flow temperature of 25 °C in its default setting. The start temperature is held constant for the days entered in...
Page 124: Night Set-Back
Appendix A (configuration instructions) When the additional reading in the flow temperature reading disappears after the last phase, this indicates that the drying process has been completed. Any power failure that oc- curs while the function is running automatically restarts the drying function. In systems in which the drying function had to be interrupted due to DHW heating (e.g. sys- tem Anl 2.1, see page 16-12), storage tank charging does not occur while the drying func- tion is active, provided it is not used for frost protection of the storage tank.

The valve is closed and the pump is switched off after t = 2 x Valve transit time. The heating is immediately switched on again when the outdoor temperature falls below the limit (minus 0.5 °C hysteresis).

Every other value entered for 'Stop charging of the buffer tank' is rated as a fixed switch-off temperature for the buffer tank charging. When SF2 (CO1 -> F06 - 1) is configured, SF2 is always used to stop the charging of the buffer tank. The storage tank charging pump is not switched off until the lag time (entered 'Valve transit time Ty' for Rk1 multiplied by 'Lag time of charging pump') has elapsed. The operation of the feeder pump UP1 is either determined by the ZP time schedule or prompted over an external demand.

Appendix A (configuration instructions) Note − Direct sunshine can cause the room temperature to increase and thus result in the prema- ture deactivation of the heating system. − When the room temperature decreases while the heating system is shortly outside its times- of-use, this can prematurely cause the controller to heat up to the 'Day set point'.

Page 133: Adaptation
Appendix A (configuration instructions) 16.2.12 Adaptation The controller is capable of automatically adapting the heating characteristic to the building characteristics. A gradient characteristic must be set in this case (CO1, 2 -> F11 - 0). The ref- erence room, where the room sensor is located, represents the entire building and is moni- tored to ensure that the room set point ('Day set point') is maintained. When the mean mea- sured room temperature in rated operation deviates from the adjusted set point, the heating characteristic is modified accordingly for the following time-of-use. The corrected value is dis- played in PA1, 2 (Flow gradient).

When the flow sensor VF4 is activated, the set point in the heat exchanger circuit is influ- enced by the system deviation in the storage tank charging circuit upon activation of the stor- age tank charging pump: if the temperature measured at flow sensor VF4 is lower than the desired 'Charging temperature', the set point in the heat exchanger circuit is increased in steps of 1 °C. When the set point in the heat exchanger charging circuit reaches the 'Max.

Appendix A (configuration instructions) 16.3.8.1 Reverse control In all systems with DHW heating and at least one heating circuit with a control valve, DHW heating can be given priority by applying reverse control. With the setting CO4 -> F08 - 1, the temperature is monitored at sensor VFx. In systems without sensor VFx in the DHW circuit (e.g. Anl 4.5, 11.0), the temperature is monitored directly at storage tank sensor SF1. If system deviations still occur after the time set in 'Activate priority in the event of a system deviation' has elapsed, the set point of the heat- ing circuit with the control valve is gradually reduced each minute until the flow temperature set point has reached 5 °C at the minimum.

Page 152: On/Off Control
Appendix A (configuration instructions) 16.4.7 On/off control The flow temperature can be controlled, for example by activating and deactivating a boiler. The controller switches on the boiler when the flow temperature falls below the set point by T = 0.5 x 'Hysteresis'. When the set point is exceeded by T = 0.5 x 'Hysteresis', the boiler is switched off again. The greater the value you choose for 'Hysteresis', the less frequent switch- ing on and off will be. By setting the 'Minimum ON time', an activated boiler remains switched on during this period regardless of the flow temperature fluctuations. Similarly, a deactivated boiler will remain switched off regardless of the flow temperature fluctuations if the Min. OFF time has been specified.

Appendix A (configuration instructions) 16.4.18 External demand for heat due to insufficient heat supply An external heat source can be demanded using the 0 to 10 V output. The function block for a request for external demand CO1 -> F18 - 1 is automatically set. The function block pa- rameters allow the transmission range to be determined. When a system deviation in Rk1 greater than 10 °C lasts longer than 30 minutes, a voltage signal corresponding to the actual demand is issued. At the same time, the Rk1 valve is forced to close. The Rk1 valve icon blinks to indicate that the operating situation has changed as long as the external heat source is released. After 30 minutes, the external demand for heat is canceled (0 V issued) and the control signal output in Rk1 is enabled again.
