Thera Design Edition - TRV Body
WITH HIGH QUALITY SURFACE FOR DESIGN RADIATORS
PRODUCT DATA
Application
The Thera Design Edition is particularly styled for use with design radiators. With their high class appearance they perfectly
fit to all kinds of ambients.
Thermostatic radiator valve bodies (TRV bodies) are fitted on
the supply or return of radiators or heat exchangers. Together

with a radiator thermostat, for example the Thera-4, they control the room temperature by regulating the flow of hot water
into the radiator or heat exchanger. The temperature of different rooms is controlled individually and energy is saved.
TRV bodies of this type have quiet operation and are fitted to
the supply or return of radiators on two-pipe systems with medium flow rates.
The valve insert can be replaced while the system is running
and without draining using the service tool (see ‘Accessories’).
TRV bodies of this type are suitable for
• Honeywell radiator thermostats with M30 x 1.5 connection
and from an optical aspect especially the Thera-4 Design
series

THERA DESIGN EDITION - TRV BODY
Function
Thermostatic radiator valves enable individual control of room
temperature and thus save energy.
The TRV body is controlled by the radiator thermostat. Air from
the room passing over the sensor of the radiator thermostat
causes the sensor to expand when the temperature rises. The
sensor acts onto the valve spindle and this causes the TRV
body to close. When the temperature falls the sensor contracts
and the spring-loaded valve spindle is opened. The TRV opens
in proportion to the temperature of the sensor. Only the amount
of water required to maintain the room temperature set on the
radiator thermostat can flow into the radiator.
Application Examples
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
Pre-setting
The TRV is open by factory setting. Pre-setting is done by first
closing the valve insert (head black with pre-setting-figure 0-9)
on top of the valve body 2 turns right and then opening to the
pre-setting-figure derived from the flow diagram.
NOTE: One complete turn refers to pre-setting-figure 10,
2 complete turns to pre-setting-figure 20 and so on.
