What is the EvoFlat system solution?
3.5.3 Additional flat station components
3. Differential pressure controller
(0.1 bar)
This component ensures a constant
differential pressure within the entire
apartment installation (heating 5-25
kPa), and optimum functioning of the
radiator thermostats. Every radiator
is therefore optimally supplied with
heat – reliably and quietly.
4. Heat meter
All EvoFlat flat stations are prepared
for the installation of water and heat
meters. The use of direct immersion
sensors is secured.
Heat meter, installed in flat station,
is an ultrasonic device for measuring
the consumption of thermal energy.
It consists of:
-calculator with integral hardware
and software for measuring flow rate,
temperature and energy consumption,
-ultrasonic flow sensor,
-two temperature sensors.
Dynamic range measurement is
1:250. Minimum flow rate for which
is guaranteed measurement accuracy,
according to EN1434, is 6 l/h. If
equipped with one of the communication
modules enables easy data
collection and transfer.
5/6. Strainer
Stations can be fitted with strainers:
heating supply (primary) and heating
return (secondary), and with a filter
in the cold water input for the hot
water controller.
7. Heat insulation
The Neopolen heat insulation
complies with the requirements of
energy conservation regulations.
8. Room thermostat - together with
electro-thermal actuator with
zone valve
Installed in the flat station’s return
side, enables hydronic balancing and
the central control of room temperature,
timer and night set-back. This
gives maximum heating comfort and
additional energy savings to end users.
Room thermostat can be manual
or programmable.
Manually adjustable room thermostat
type RMT-230 with:
– adjustable temperature: 8-30 °C,
– power: 230 V AC,
– switching differential (on/off): 0.6 K
is supplied as standard.

What is the EvoFlat system solution
For users with higher demands for
comfort it is possible to use programmable
thermostats TP5001 with a
weekly program (5/2) and TP7000 with
a daily program (6 intervals), and with
the possibility of lowering the night
temperature.
Piping and connections
All elements built into flat station are
connected by pipes made of stainless
steel. Extremely low roughness of pipe
and special way of bending ensures
silent operation and small dimensions
of the stations. Connection elements
used are made from brass (connection
fittings, elbows and T-pieces). All elements
in the flat stations are connected
with detachable fittings to allow easy
replacement of parts and easy maintenance.
Rated nominal pressure of flat
stations is PN 10 (16) as standard.
Options
All flat stations can be equipped with
domestic hot water circulation set on
request. It consists of the pump with
timer, thermostat or both and the required
connection lines.
