Multibox 4 is used for decentralized control of underfloor heating. Due to the additional supply shut-off heating surfaces can be locked individually.

Multibox 4 K, RTL and K-RTL

Technical description

HEIMEIER Multibox 4 K, Multibox 4 RTL and Multibox 4 K-RTL flush box with frame, cover plate and fixing bars, for controlling, for instance, floor heating systems without auxiliary power.
All Multibox 4 models are equipped with an additional supply shut-off incl. vent valve. Heating surfaces can be shut-off individually.
Multibox 4 K
for the individual room temperature control with thermostatic valve of, for instance, floor heating systems.
Multibox 4 RTL
for maximum limitation of the return temperature with return temperature limiter of, for instance, combined floor/radiator heating systems.
Multibox K-RTL
for the individual room temperature control and maximum limitation of the return temperature with thermostatic valve and return temperature limiter of, for instance, combined floor/radiator heating systems.
All models optionally with cover and visible graduation cap in white RAL 9016 or chrome-plated.
The flush box has an overall depth of 60 mm. Flexible mounting thanks to variable spacing between flush box and cover of up to 30 mm. The cover can compensate for slanted mounting of the flush box of up to 6° on each side.
Thermostatic head K with liquid-filled thermostat. High actuating power, minimum hysterisis, optimum shutting time. Stable control properties even with small design control differences (<1 K). Meets EnEV and/or DIN V 4701-10. Cue number 1-5. Anti-freeze protection. Temperature range 6° C - 28° C.
Return Temperature Limiter (RTL) with expanding substance-filled thermostat. Cue number 0-5. Temperature range 0° C - 50° C.
With Multibox K-RTL Cue number 10-50. Temperature range 10° C - 50° C.
Body made of gunmetal. Thermostatic inserts with stainless steel spindle and double O-ring seal. Outer O-ring can be replaced without system drainage.
All models are equipped with a venting valve.
Pipe-side G 3/4 adaptor with cone suitable for compression fittings for plastic, copper, precision steel and multi-layer pipe.
For HEIMEIER valves, only use the corresponding, designated HEIMEIER compression fittings (designation e.g. 15 THE).

Multibox 4 F

Technical description

HEIMEIER Multibox 4 F flush box with frame including thermostatic head, cover plate and fixing bars for the individual room temperature control with thermostatic valve of, for instance, floor heating systems, without auxiliary power.
Multibox 4 F is equipped with an additional supply shut-off incl. vent valve. Heating surfaces can be shut-off individually.
Through a capillary tube, the temperature sensor liquid of the thermostatic head acts on the bellows in the valve adaptor. There is therefore never any change in the appearance of the cover with thermostatic head – irrespective of the installation depth.
All models with cover and visible graduation cap in white RAL 9016.
The flush box has an overall depth of 60 mm. Adjustable mounting thanks to variable spacing between flush box and cover of up to 30 mm. The cover can compensate for slanted mounting of the flush box up to 6° on each side.
Thermostatic head with liquid-filled thermostat. High actuating power, low level of hysterisis, optimum shutting time. Stable control properties even with small design control differences (<1 K). Meets EnEV and/or DIN V 4701-10. Cue number 1-5. Anti-freeze protection. Zero position (valve opens at approx. 0° C). Temperature range 6° C - 27° C.
Body made of gunmetal. Thermostatic insert with stainless steel spindle and double O-ring seal. Outer O-ring can be replaced without system draining.
Pipe-side G 3/4 adaptor with cone – suitable for compression fittings for plastic, copper, precision steel and multi-layer pipe. For HEIMEIER valves, only use the corresponding, designated HEIMEIER compression fittings (designation e.g. 15 THE).
