Jupiter Dynamic S1 manifold with dynamic flow control
The Jupiter Dynamic S1 manifold adjusts the flow rate in the individual heating circuits directly in litres/hour. This means that hydraulic balancing is achieved in one simple operation. The set flow rate is constantly adapted i.e. if the rate becomes too high due to adjacent closing circuits, the Jupiter Dynamic S1 manifold automatically controls the flow to the set value.
Traditional underfloor heating manifolds are balanced with all circuits opened. During operation it is likely that not all circuits are open simultaneously. This increases pressure through open circuits which affects output. The Dynamic S1 manifold ensures constant flow through all circuits.
Key features:
Guarantees constant room temperatures
Automatic hydraulic balancing due to integrated flow control inside each thermostatic insert
Flow indicator to check individual circuit operation
Contributes to lower running costs
Time and cost saving commissioning solution
German AISI 304 stainless steel manifold
Function:
A regulating part is set to the calculated control rate by turning the digit cap with the setting key or an 11 mm end wrench. If the flow rate increases at the valve the rising pressure moves the sleeve, thus constantly limiting the flow to the set value. The set flow rate is therefore never exceeded.
If the flow rate drops below the set value a spring presses the sleeve back to its original position.

Sample calculation
Target:
Set value of Jupiter Dynamic S1 manifold flow controller
Given:
Heat flow, heating circuit Q = 1120 W
Temperature spread Δt = 8 K (44/36°C)
Solution:
Mass flow m = Q / (c · Δt) = 1120 / (1.163 · 8) = 120 kg/h
Flow regulator setting at manifold: = 12
Q = Heating performance
Δt = System differential temperature
Δp = Differential pressure
Sample:
Q = 1000 W, Δt = 15 K
Setting value: 6 (≈ 60 l/h)
Δp min. 30 - 150 l/h = 17 kPa
Δp min. 150 - 300 l/h = 25 kPa
