manifold with regulating flow meters
collector with shut-off valves
mounting brackets
thermostatic valve with thermostatic head and separate immersion temperature sensor for constant temperature control
regulating compression fittings
circulation pump with wiring
safety thermostat
2x automatic air vent valves
thermometer
2x rotary drain valves

Recommended for a radiator-circuit temperature gradient of +75 °C / +65 °C

Fitted with circulation pump: DAB.EVOSTA 2 40-70/130

Switching off the circulation pump is not part of the manifold; it can be handled by a higher-level control system or by the IVAR.AC 614 E control thermostat for circulation pumps.

Pump rotated to front position A = 165, installation depth = 160 mm

Pump rotated to side position A = 220, installation depth = 132 mm

Note:

The thermostatic valve at the set inlet can alternatively be replaced with a thermostatic valve with Vats flow, Kv, type VDS 01, 02.

Attention:

the flow meter is integrated into the regulating compression fitting on the inlet water
the set is NOT intended for use in combination with a condensing boiler or a heat pump
the seller is not liable for functional defects caused by dirt/impurities in the system

Warning:

Before commissioning the , especially when combining underfloor and radiator heating, it is strongly recommended to flush the entire system according to the manufacturer's instructions. We recommend treating the system with GEL.LONG LIFE 100.

Manifolds are installed in cabinets; their recommended lengths are given in the manifold table. Installing the manifolds at the highest point is practically a requirement (watch out for level changes in floor plans). An exception is venting small underfloor heating loops on a higher floor via a bathroom towel radiator/ladder rail. If an underfloor system is installed only in bathrooms, pipe from the return branch of the radiator system with a polyethylene sleeve can be used, or a direct-acting temperature regulator can be fitted at the end of this parallel loop to ensure cooling to a low-temperature level (note! it must be thermally separated from the radiator circuit return so that it is not thermally influenced).
