Mounting
Selecting the mounting site
► When selecting the mounting site take into consideration that the
temperature measurement is influenced if the operating unit is
mounted on an outer wall or near heat sources.
Mounting the drive unit
► Turn the radiator on before mounting. The radiator valve must be
open.
HINT: The correct setting of the valve is best checked with the central
heating switched on. If the valve is correctly mounted, the
radiator will become warm.
Separating the drive unit from the valve lantern
► Remove the old radiator
controller, if necessary.
► To open the retainer brack-
et, turn the control knob (1)
so the tip points upwards.
