Thermostatic Radiator

Valve Head

RT86.2

with remote adjuster

• Individual room temperature control

• Designed for use with radiator valves where there is no accessibility for set-

point adjustments (e.g. behind radiator panels)

• Suited for single- or two-pipe heating systems with weather-compensated flow

temperature control

Function

• Maintains the room temperature at the required level

• Infinite actuation of the radiator valve by means of a liquid-filled temperature sensing

element (regulation of the volumetric flow)

• Acquires and compensates heat gains from solar radiation, people, lighting, etc.

• Proportional control

Equipment combinations The RT86.2 can be combined with radiator valves type VD1...,VE1..., VD2..., VE2..., VU2... or VUC515... (refer to data sheet CE1N2150E under «Type summary»). The temperature sensing element is accommodated in the remote adjuster. If required, the RT86.2 can be equipped with the RT56.15 thermostatic head (with frost protection function) or with a manual knob (in place of the 56.05 thermostatic head).
