Fitting notes
• To ensure optimum room temperature control, it should be made certain that ther-
mostatic heads with built-in sensor are always mounted horizontally so that the
room air can freely circulate around the sensor. This means that the head must not
be covered by panels, furniture and the like.
• Also, the head must not be exposed to direct solar radiation and draughts of cold
air.
• In locations where these requirements cannot be met, the version with a remote
sensor, type RT76.052, must be used.
• The head can also be fitted while the plant is in operation. A robust metal nut facili-
tates direct fitting to the VD…, VE…, VU…, VPC…, VPD…, VPE… valves without
the use of tools.

• Thermostatic heads with built-in sensor should be fitted horizontally.
