RC35 programming unit

The RC35 programming unit (
the Logamatic EMS control system and supplied with
power via a 2-core BUS cable. The RC35 programming
unit can either be clipped into the Logamatic BC10 base
controller on the boiler, or fitted on a wall mounting
bracket inside the living space. Installed in the living
space, the programming unit RC35 is also suitable as a
convenient room temperature controller.

With the RC35 programming unit in its standard version,
one heating circuit without mixer can be controlled in the
operating modes room temperature-dependent,
weather-compensated or weather-compensated with
room temperature hook-up. For room
temperature-dependent control or for room temperature
hook-up, install the RC35 programming unit in the
reference room. If the reference room is not the location
where the RC35 programming unit is installed, an external
room temperature sensor can be connected at the wall
mounting base.
The RC35 programming unit is equipped with a
programmable 6-channel digital time switch with eight
standard programs for the graphic display of the
3
switching cycles and the outside temperature (with
integral "Weather station"). Individual programs can also

be created for each heating circuit in conjunction with the
Logamatic EMS control system and/or the WM10 and
5
MM10 modules. An individual time channel is available for
DHW heating incl. control of a DHW circulation pump.

The standard functions also include thermal disinfection,
which can be adjusted as required, and once only DHW
heating. All important information regarding the heating
system, including fault messages, room temperature, time
and days of the week can be captured with the RC35
programming unit and displayed "in plain text" on the
backlit LCD with graphic capabilities (
Selector keys (
selection of the heating modes "Automatic, Constant
heating "and" Constant setback". The integral LED
signals the current operating mode.
The RC35 programming unit regulates the low loss
header and one heating circuit without mixer directly
downstream, in conjunction with the WM10 low loss
header module, three further heating circuits in
conjunction with the MM10 mixer modules, plus the solar
DHW heating in conjunction with the SM10 solar module
(system example
The RC35 programming unit also includes some special
functions, e.g. a "Holiday function" for the entire system
or, in conjunction with the WM10 and MM10 modules, for
each individual heating circuit.
In addition, extensive service functions can be utilised,
e.g. "Monitor function", "Function test", "LCD test", "Fault
monitoring", "Fault message" "Scanning the heating
curve".
The functions of the RC35 programming unit are
accessible at several levels that are called up in
accordance with the simple and proven "Push & Turn"
concept. For the end user, two control levels are available,
divided into standard functions and extended functions.
At the service level, contractors can make adjustments,
e.g. for the heating circuits or DHW heating.
