This Basic Documentation covers two types of heating controllers, the RVL470 and the
RVL469. The RVL470 is described in every detail, not so the RVL469.
The RVL469 contains functions of the RVL470 and is therefore integrated in the present
Basic Documentation. But only the section "RVL469" refers to the specific functionality
of the RVL469 (functions that differ from those of the RVL470). In all the other chapters
and sections, the RVL469 will not be specifically mentioned.
• The RVL470 is a multi-functional heating controller for use in residential and non-
residential buildings. It is suited for weather-compensated flow temperature control of
heating zones with or without room temperature influence or for demand-compen-
sated control of heat generating equipment (pre-control)
• It is used in plants with own heat generating equipment or with a district heat connec-
tion
• The RVL470 is capable of communicating with other units via LPB (Local Process
Bus)
• The RVL470 has 6 types of plants pre-programmed. When a certain plant type is se-
lected, all functions and settings required for that particular plant will be activated
• For the direct setting of the heating curve, the proven bar is used, but digital adjust-
ment of the heating curve is also possible. For readjustment of the room temperature,
a setting knob is used (L&S standard)
• All other parameters are set digitally using the operating line principle (L&S standard)
• Operating voltage AC 230 V, CE conformity, overall dimensions to DIN 43700
(144 144 mm)
*
The RVL470 is a compact controller requiring no plug-in modules or cards.

For water 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:
–
Clamp-on temperature sensor QAD22
–
Immersion temperature sensor QAE22...
–
Immersion temperature sensor QAP21.3 with integrated connecting cable
• For the room temperature:
Suitable are all types of temperature sensors that use a sensing element LG-
Ni 1000 Ω at 0 °C. The following type is presently available:
–
Room temperature sensor QAA24
• For the outside temperature:
Outside sensor QAC22 (sensing element LG-Ni 1000 Ω at 0 °C)
–
– Outside sensor QAC32 (sensing element NTC 575 Ω at 20 °C)
