4 IMI HEIMEIER / Floor Heating Control / Dynalux Application Dynalux adjusts the flow rate with flow meters in the individual heating circuits directly in l/min. This means hydraulic balancing is achieved in simple operations. This makes Dynalux heating circuit manifolds a time and costsaving solution. The quantities of water distributed in this way correspond to maximum requirements. This ensures optimum temperature distribution, saves energy and increases comfort. 1. STAP differential pressure controller. STAD balancing valve. Globo P pump ball valve. Room thermostat. Thermostat P with switch clock Thermal fluid To stop any damage and scale in hot water heating systems, the composition of the thermal fluid is to conform to VDI Directive 0. For industrial and longdistance energy systems, see applicable codes VdTÜV and 1/AGFW FW 10. Mineral oil in the thermal fluid and/or all kinds of lubricants containing mineral oil lead to considerable swelling and, in most cases, to the failure of EPDM seals. When using nitrite-free antifreeze and anti-corrosive based on ethylene glycol, technical advice especially on additive concentration is to be taken from the anti-freeze/anti-corrosive manufacturer s documentation. Filling, flushing and venting Each heating circuit must be individually filled, flushed and vented. Product lifetime and system performance strongly depend on proper commissioning. We refer to technical standards EN 1, VDI0 and ON H19-1 to be carefully attended. Functional heating Carry out functional heating of heating screed conforming to standards in keeping with EN 1-. Earliest start for functional heating: Cement screed: 1 days after laying Anhydrite screed 7 days after laying Begin 0 C - C flow temperature and maintain for days. Then set maximum design temperature and maintain for days. Flow temperature can be regulated by controlling the heat generator. Do not exceed maximum floor temperature at the heating pipes: Cement and anhydrite screed: C Poured asphalt screed: C according to screed manufacturer s technical advice! Refer to the screed manufacturer s information!

Sample calculation 1 Target: Pressure loss in the least efficient heating circuit Given: Heat flow, incl. floor loss Q = 190 W Temperature spread Δt = 8 K (/ C) Heating pipe ø = 17 x mm Pipe length incl. feed I = 90 m Solution: Mass flow m / (c Δt) = 190 / (1,1 8) = 10 kg/h (,7 l/min) Pressure loss flow meter (fully open) Δpv = 19 mbar Pressure loss thermostatic valve Δp TRV =, mbar Pressure gradient in heating pipe R = 1. mbar/m Pressure loss in the heating pipe Δp R = R I = = 108 mbar Total pressure loss in the heating circuit 1 Δp HK1 = Δp V + Δp TRV + Δp R = 10, mbar Sample calculation Target: Set value of further heating circuits with Dynalux flow meter Given: Heat flow, heating circuit Q = 110 W Temperature spread Δt = 8 K (/ C) Solution: Mass flow m = Q / (c Δt) = 110 / (1.1 8) = 10 kg/h Flow meter setting at Dynalux manifold: 10 kg/h / 0 kg/min l/min To preset the system, all the manual and thermostatic valves in the entire circuit must be opened completely. Once the entire system has been preset, check the initial settings again and make further adjustments where necessary. Once the definitive settings have been made, the locking cap must be used to secure the flow indicator so that no unauthorised or accidental adjustments can be made.
