Recommendations:
Room temperature is not correct, especially in mild weather:
Readjust the room temperature with setting knob
a room temperature change of about 2 °C
Room temperature is not correct, especially in cold weather:
Readjust the heating curve slope with setting knob
Room temperature too high: reduce slope by about 0.2
Room temperature too low: increase slope by about 0.2
Room temperature is not correct, especially at night:
Readjust the setback with setting knob
4.1.3

Selection of operating mode

The required operating mode is set with the selector on the front of the controller. Also,
using an external switch connected to terminals A6-MD, the current operating mode
can be overridden from a remote location:
Contact closed: the controller operates in protection mode
Contact open: the controller operates in the mode selected with the slider

Mounting

4.2.1

Mounting location

The controller should be mounted in a dry location, such as the boiler room.
The permissible ambient temperature in operation is 0...50 °C.
The RVP201/211 can be mounted as follows:
In the control panel, on the inner wall or on a top hat rail
On a panel front
In the control panel front
In the sloping front of a control desk
4.2.2

Mounting methods

The RVP201/211 is designed for three different mounting methods:
Wall mounting: the base is secured to a flat wall with the help of three fixing screws
Rail mounting: the base is fitted to the top hat rail
Flush panel mounting: the base is fitted in a panel cutout measuring 138 × 92 mm
4.2.3

Installation

Local regulations for electrical installations must be complied with
The cable lengths should be selected such that the control panel front can be easily
opened
Cable tension relief must be ensured
The cables of the measuring circuits carry extra low voltage
The cables from the controller to the regulating unit and to the pumps carry
AC 24...230 V mains voltage
Sensor cables must never be run parallel to mains carrying cables connecting loads
such as actuators, pumps, burners, etc. (safety class II to EN60730)
Maximum limitation of the boiler temperature is not a safety function; for this pur-
pose, a thermostat or limit thermostat must be used and connected to L–F1/F4
