Stainless Steel Manifold

With a ¾” port and air vent on each manifold arm, flushing, filling and removing air from systems during commissioning is simple. Each flow arm is fitted with a thermo-manometer, making pressure testing quick and reliable, with 0-5 l/min Taconova flow gauges providing precise, confident and efficient system balancing.

Manifold Key Benefits

N

Reliable performance

Rigorous tests conducted at the manufacturing stage ensure that the system is reliable and performs as required
N

Constructed in single piece

The laser etched, brushed Type 304 austenitic stainless steel manifolds will perform well and look good doing so for years to come
N

A choice of circuits

Available in 2-12 ports to match your requirements
N

Taconova flow meters

Incorporates the precise and proven performance of the flow meter technology only available from Taconova
N

No expensive extras

The S3 manifold is fully equipped as standard making commissioning easy and operation efficient
N

Acoustic damping

The manifold brackets come with acoustic inserts to keep operational noise to a minimum

Manifold S3 Mixing Unit

The Warmup S3 Mixing Unit is added to the manifold whenever local water temperature regulation or hydraulic separation of the primary circuit is required.

The system’s temperature can be limited to any value between 20°C to 60°C, enabling screeds to be commissioned at 25°C in line with British Standards and set to the most efficient temperature thereafter, with an anti-tamper device ensuring it continues to operate efficiently.

The unique mixing unit is designed to complement all heat sources, not just gas condensing boilers, including heat pumps, biomass and solar thermal.  Without the inclusion of the Warmup Mixing Unit overheated water due to sterilisation cycles or peak solar gain could otherwise pass overheated water into the floor causing damage.

Mixing Unit Key Benefits

N

3-Way mixing

The unique mixing unit provides full 3-way mixing control making it compatible with all heat sources
N

Adjustable bypasses

Featuring integral primary and secondary circuit bypasses, the mixing unit makes commissioning easy without needing to purchase expensive extras
N

Grundfos UPM3 circulator

When set to operate in its constant pressure mode, this 70kPa circulator makes setting flow meters simple, with flow rates remaining constant whatever the manifold load is
N

Robust construction

The nickel plated brass construction is both robust and corrosion resistant, complementing the aesthetics of the Warmup S3 manifold
N

Circulator isolation

The inline isolation valve located above the circulator prevents water bypassing circuits during filling and allows the circulator to be easily replaced when necessary
N

Low-noise operation

Advanced mixing unit design minimises both mechanical and hydraulic noise

Manifold S3 Actuator

The WHS-M-S3-ACT230 actuators are used in combination with the Warmup S3 Manifolds to control the circuit valves. While operational, the actuator consumes less that 1W of power, making it the most efficient actuator in its class.

The actuators are supplied ‘latched open’ so they can be easily mounted and commissioned. In this condition the indicator disc is only marginally raised, with no blue visible.
Upon completing their first full power cycle the actuator then operates in a normally closed manner, open the valve when power is supplied based on heating demand.

For multi-zone manifold control, Warmup S3 Actuators are added to each circuit. Using less than 1W each while active, this 5th generation actuator is water resistant to class IP54, extremely reliable and environmentally friendly.

They are supplied ‘latched open’ for easy ‘click’ mounting out of the box.  During operation the clear 360° indicator shows the current valve position, from its off, normally closed, position to being fully open.  Providing a 100N actuating force on the valve, it prevents any unintentional flow through the valve during operation or pressure testing.

Actuator Key Benefits

N

360° Status indicator

The clear, blue disc on top of the actuator provides visibility at any angle and tactile indication in hard to see locations
N

Easy mounting

With a separate mounting collar and actuator, it is easy to screw the collar on before simply clipping the actuator in place
N

Energy Efficient

At just 1W operating power, this 5th generation actuator is extremely energy efficient

Manifold S3 Isolation Valves

The WHS-M-S3-VALVES kit allow for the manifold on your underfloor heating system to easily be isolated from the primary circuit. The kit has been specified to fit the WHS-M-S3-XX manifold range when equipped either with or with out the WHS-MS3-MIX mixing unit. With the WHS-M-S3-VALVES isolated, the manifold can be filled, drained, pressure tested etc, without affting the primary circuit.
