2 About the product
The Comfort+ II RF contains the programmable, wall mounted
control unit Comfort+ II RF for the radio-controlled remote
control and the Key which is implemented in the heat source.
2.1 User interface
The control unit is a room temperature-dependent controller.
The control unit can be used together with an outside
temperature sensor (wireless or tethered) as a weather-
compensated wireless controller. The purpose of the control
unit is to control a heating system via radio remote control and
it is mounted on the wall. The control unit is suitable for central
heating and DHW heating via a heating controller with
modulation. Up to six switching times can be set in the central
heating and DHW program.
The modulation facilitates intelligent communication with the
heat source so the required room temperature is obtained as
efficiently as possible. The burner may stop shortly before the
required room temperature is reached in order to save fuel/
money and minimise the extent to which the required room
temperature is exceeded. This behaviour, together with lower
radiator temperatures, is normal. The required room
temperature must only be set once at the control unit. Open the
thermostatic valves at the radiators in the room in which the
control unit is used completely and set the output of the
radiators as low as possible via adjustable lockshield valves or
set the manual valves as low as possible.
All programming and adjustment can be carried out
conveniently from the living space which means the
Comfort+ II RF is the perfect choice for heat sources that are
difficult to access.
