Page 7: Brief Description And Features
Summary Brief description and features RVP201 and RVP211 are heating controllers designed for use in smaller plants. The only difference between the two types of controllers is the d.h.w. heating function: RVP201: without d.h.w. heating RVP211: with d.h.w. heating The RVP201/211 controller is designed for use in smaller residential and non- residential buildings that have their own heat generating plant The RVP201/211 is a flow temperature controller. -

Page 13: Acquisition Of Actual Values
In the case of serious faults that do not allow the RVP201/211 to ensure control, a fault message will be generated. This is indicated on the controller front by the LED which starts flashing when the current operating mode is overridden. -
Page 14: Temperature
"6 Mechanical design". 3.3.3 Compensating variables Outside temperature The RVP201/211 differentiates between three types of outside temperatures: The actual outside temperature (T The attenuated outside temperature (T ). It is generated by filtering the actual out- side temperature by the building time constant. This means that compared to the ac- tual outside temperature, the attenuated outside temperature is significantly damp- ened, thereby representing the long-term development of the outside temperature. - Page 15 In the case of short-time variations of the outside temperature, the composite outside temperature (T ) prevents the control from responding too quickly. With weather-compensated control, the RVP201/211 only uses the composite outside temperature. (B9) Generation of composite and attenuated outside temperature...

Page 16: Heating Curve Chart
The heating curve slope is set with a setting knob on the front of the controller. 16/46 Siemens Heating controllers RVP201 and RVP211 CE1P2464en Building Technologies 3 Technical design 2017-07-21... - Page 17 The basic setting is to be made in agreement with the planning documentation or ac- cording to local practices. The heating curve is based on a room temperature setpoint of 20 °C. 17/46 Siemens Heating controllers RVP201 and RVP211 CE1P2464en Building Technologies 3 Technical design 2017-07-21...

Page 21: Limitations
The burner's switch-off point cannot be higher than the maximum limit value. In that boiler temperature case, the switch-on point will be lower by the amount of the set switching differential. This function can be disabled. 21/46 Siemens Heating controllers RVP201 and RVP211 CE1P2464en Building Technologies 3 Technical design 2017-07-21... -

Interactions with room units 3.9.1 General Room units can act on the RVP201/211 only if the controller works in one of the two automatic modes The room temperature acquired by a room unit is adopted by the RVP201/211 at terminal A6. If the room temperature acquired by the room unit shall not be consid- ered by the control functions, the room authority must be set to 0 %. -

If the controller is used without a time switch (RVP201.0 or RVP211.0), the space for the time switch is covered up with a hinged cover. If a time switch is fitted at a later time, the appropriate hole in the cover must be cut out with a knife. -

6.2.1 General The RVP201/211 has an opening for fitting a plug-in type time switch. If desired, the time switch fitted can be replaced by another type (refer to "1.2 Type summary"). The time switch is simply plugged in. The electrical connections to the con- troller are established via a terminal strip so that no wiring is required. - Page 41 The resolution is thus one hour. However, since – for mechanical reasons – at least two tappets need to be tilted together to set one heating period, the shortest possible heat- ing period is two hours. 41/46 Siemens Heating controllers RVP201 and RVP211 CE1P2464en Building Technologies 6 Mechanical design 2017-07-21...
