T6101, T6102 Underfloor Heating Controllers

CONTROL OF UNDERFLOOR HEATING LOOPS

PRODUCT DATA

Design

The sets constist of:

•Underwall case with lid

•Protective render lid for use during building phase

•Thera-RTL or Thera-3 thermostat

•Thermostatic valve PN10, DN15, double or horizontal angle body, with external threads to ISO 228 (Eurocone). Connections for copper, plastic or composite tube - see 'Accessories'

•Air vent

Materials

•Handwheel and socket made of plastic, white to RAL9016

•Lid made of sheet steel, white to RAL9016

•Underwall box and render lid made of dark grey plastic

Application

The underfloor heating sets are used to control underfloor heating loops with or without additional radiator.

The RTL-Set limits the return temperature of an underfloor heating loop in combined underfloor/radiator heating systems. The thermostat is set between 20 and 50°C (68 and 122°F) depending on the desired return temperature. It is available with visible or concealed thermostat. The RTL-Set with the concealed thermostat is set only once whereas the setting of the visible thermostat can easily be changed anytime.

The Room Control-Set controls the flow of the medium through the underfloor heating loop depending on the ambient room temperature.

As the return temperature is controlled, the system designer has to make sure that the supply temperature is suitable for the floor design of the underfloor heating system. A too high supply temperature may result in damage to the floor and to the floor construction.

Features

•Easy readability of set temperature from every angle

•Equipped with concealed limiting and blocking tabs

•Valve inserts follow AT-Concept

T6101, T6102 - UNDERFLOOR HEATING CONTROLLERS

Function

Return temperature limiter are installed in the return of a radiator or underfloor heating loop. When the return flow temperature rises the valve closes and the flow through the heating loop is throttled. When the return flow temperature decreases the valve opens and the flow increases.

The function of the Room Control-Set is identical except for the control mode. The thermostat senses the ambient room temperature and controls the flow of the medium through the heating loop accordingly.

Please Note:

•To avoid stone deposit and corrosion the composition of the medium should conform with VDI-Guideline 2035

•Additives have to be suitable for EPDM sealings

•System has to be flushed thoroughly before initial operation with all valves fully open

•Any complaints or costs resulting from non-compliance with above rules will not be accepted by Honeywell

•Please contact us if you should have any special requirements or needs
