11.0 Description of VX Solo variants
11.1 VX Solo II (T°C 200u)
Differential pressure controller
(Standard on systems with self-acting thermostatic valve).
The differential pressure controller reduces the fluctuating
pressure in the district heating network to a small and invariable
operating pressure in the substation.
The required room temperature is controlled on your radiator ther-
mostats.
Differential pressure controller AVPL
AVPL is a self-acting differential pressure controller for PN 16 with
adjustable differential pressure setting and the differential pressure
controller can be set at any differential pressure between 5 kPa and
25 kPa (0.05 bar and 0.25 bar).
The preset factory setting of the controller is 10 kPa (0.1 bar).
The differential pressure can be set by means of an Allen key NV 3. 1
turn corresponds with 1 kPa (0.01 bar).
The controller settings can be changed in accordance with the en-
closed producer instructions:
Differential pressure controller (PN 16) AVPL
Return mounting, adjustable setting
Alternative differential pressure controller TD200
Alternatively a diffferential pressure controller type TD200 can be
mounted in the substation.
This type of differential pressure controller is preset from factory and
should not be adjusted afterwards.
Substation for indirect heating for single-family, semi-detatched and
terraced houses as well as flats. With one heating circuit for radiator
or floor heating. For wall-mounting.
The temperature for the heating circuit is controlled by a self-acting
thermostatic valve T°C 200u.
Please note:
Your substation may look different than the substation shown, as
variants with other components may be supplied.
Instructions for the fitted components will always be supplied to-
gether with the substation.
