1 Summary
1.1 Brief description and key features
• RVD110 / RVD130 are multifunctional district heating controllers for flow temperature
control of heating circuits and for the control of d.h.w. heating
• Their exclusive field of use are plants with district heat connection in smaller residen-
tial and nonresidential buildings
• The RVD110 has 3 plant types preprogrammed, the RVD130 has 8. When a certain
type of plant is selected, all functions and settings required for that particular plant
will be activated
• The RVD110 / RVD130 are designed as flow temperature controllers. The following
modes of control are possible:
− Weather-compensated only
− Weather- and room temperature compensated
− Room temperature-compensated only
• The difference between the RVD110 and RVD130 is the kind of d.h.w. heating:
− RVD110: 3 plant types, designed for straightforward d.h.w. heating with storage
tanks
− RVD130: 8 plant types, also suited for the more complex d.h.w. heating systems
that employ instantaneous d.h.w. heating
• In terms of regulating units, the RVD110 / RVD130 is designed for the control of 2-
and 3-port valves as well as diverting valves and pumps
• For the direct setting of the nominal room temperature setpoint, a knob is provided.
All the other parameters are set digitally using the operating line principle
• Key design features: Operating voltage AC 230 V, CE conformity, overall dimensions
to DIN 43700 (96 × 144 mm)

1.3 Equipment combinations
1.3.1 Suitable sensors
• For the flow temperatures:
Suitable are all types of temperature sensors that use a sensing element LG-Ni 1000
Ω at 0 °C. The following types are presently available:
− Strap-on temperature sensor QAD22
− Immersion temperature sensor QAE22...
• For the return temperatures:
The following types are presently available:
− Strap-on temperature sensor QAD22 (sensing element LG-Ni
1000 Ω at 0 °C)
− Immersion temperature sensor QAE22... (sensing element LG-Ni 1000 Ω at 0 °C)
− For the primary return temperature (B7), also commercially available sensors with
a sensing element Pt 500 Ω
• For the outside temperature:
− Outside sensor QAC22 (sensing element LG-Ni 1000 Ω at 0 °C)
