1 Application
The HEIMEIER Radio control F radio frequency system
for individual temperature control of underfloor heating
systems consists of a microprocessor-controlled receiver,
with or without digital timer, and a number of room
transmitters. No wiring is required between the bat-
tery-driven transmitters and the receiver. The transmitter
is an electronic fuzzy controller with an integrated sensor.
The setpoint value range can be set to between 5 °C and
30 °C.

3 Functional description
The transmitter detects an actuating signal based on a
variable set temperature. This signal is transferred to a
receiver by radio transmission. The final control elements
for heating and cooling applications are switched via the
receiver.
The transmitting frequency is used throughout Europe
for this purpose. The transmitting power is very low. It is
much lower than that of a mobile telephone. Moreover,
the transmitter is only activated every 10 min.
The transmission quality is enhanced by using special
test procedures and repeating transmissions. Transmitter
and receiver are aligned to each other via the "learning
mode".
3.1 Control mode
The controller supports two control modes which can
be selected via jumper BR 3.
Fuzzy mode with PWM:
This mode is very similar to a continuous-action control.
It is particularly suitable for electrothermal actuators and
pumps.
The controlled variable calculated from the difference be-
tween set and actual temperature is displayed as a vari-
able pulse-pause-ratio (pulse width modulation =PWM).

The sum of pulse and pause times is always 10 minutes.
In the case of larger temperature differentials, the con-
troller switches permanently on or off, e.g. in the case of
a temperature setback
The control algorithm attempts to keep the room tem-
perature constant without switching temperature dif-
ference. For that purpose it is necessary that heat be
requested (however, to a lesser extent) even if the set
temperature has already been reached.
ON-OFF mode:
The heating system works at 100% capacity until the
set temperature is reached. Above this temperature, the
heating system is switched off.

Temperature
This mode is used where frequent switching is to
be avoided,say,in the case of burner control or if
a rise in temperature above or a fall in temperature
below a predetermined limit is to be signalled.
In the case of inexplicable malfunctions, the "Reset"
button should be pressed.
3.2 Mode selector switch ( è ê ë í )
The following modes of operation can be set by means
of this switch:
è Automatic mode
ê Permanent normal temperature
ë Permanent setback temperature
í Off
è Automatic operation:
In automatic mode, time-dependent setback of the
room temperature is activated through the timer in-
tegrated in the receiver. The receiver without timer will
permanently control the normal temperature.
ê Permanent normal temperature:
The normal temperature selected on the adjustment
knob is permanently maintained. There is no change
in the time setting.
ë Permanent setback temperature:
The temperature selected on the adjustment knob is
permanently reduced. There is no change in the time
setting.
The setback value (-2 K, -4 K) can be selected in the
thermostat via jumper BR 2.
í Off:
There is no control action. The radio transmission to
the receiver, however, remains active.
Function 3.4 ... timer... is possible.
Notes:
If the batteries are removed for more than one hour,
the receiver changes to alarm mode, the heating sys-
tem operates at 30 % capacity.
3.3 Heating / cooling switch-over
The switch for changeover is located under the flap.
Thus, the controller can be switched from summer to
winter mode.
For cooling, the energy-saving setback level is +2/+4 K
above the comfort temperature.
U Heating as temperature rises, energy consump-
Temperature
tion is reduced
P Cooling: as temperature rises, energy con-
sumption is increased
3.4 Energy-saving/timer/party mode
For activating the normal temperature for a
limited period of time.
The switch-on time can be selected freely from 1 up
to 15 hours (in one-hour steps).
After this period of time has elapsed, the controller
switches again to the state selected on the mode se-
lector switch (è,Ñ or í).
è Automatic mode (= party function):
The normal temperature is activated for the timer dur-
ation.
è Normal operation
The timer has no effect (no flashing of the indicator
lamp)
ë Setback temperature (= energy-saving mode):
The timer causes temperature to be switched between
the normal and the selected setback temperature.
í OFF (= energy-saving mode):
The timer causes temperature to be switched between
the normal temperature and OFF.
Activating the timer:
• Every time the ì button is pressed, the timer operating
time is increased by one hour. Pressing once = 1 hour,
pressing twice = 2 hours ... Pressing 15 times = 15
hours, pressing 16 times = 15 hours
Each time the push-button is pressed, the indicator lamp
will light up briefly. If it is pressed more than 15 times,
the time setting will remain unchanged at 15 hours. The
lamp will no longer light up.
The button should be pressed in rapid succession. If not
pressed for more than approx. 15 sec., setting will start
again at one hour.
If the push-button is pressed again during the timer
operating time, time will start again at 1 hour.
Termination:
• Pressing the reset button or
• Toggling the mode selector switch
will switch the timer off.
3.5 Valve protection
This function prevents valve sticking e.g. during summer
time (inclusion of particles). This protective function is
activated every day for approx. 10 min. It is repeated
every 24 hours, calculated from the last use of the reset
button.
This function can be switched on with jumper BR 1.
3.6 Function of indicator lamp
The following functions are indicated by means of this
lamp:

push-button

3.8 Battery change
If the indicator lamp lights up briefly every 15 sec., the
batteries must be changed within the next few days
(under the hinged lid).
Observe correct polarity.
Please use the type of battery specified under section 6.
"Technical data". The quality of the battery determines
its life.
Following a replacement of batteries, the controller will
continue to operate in its previously selected function.
If the timer is operating it will be cancelled.
4 Installation
The temperature sensor can be arranged within the room
where it is considered best by the user. However, for per-
fect temperature control it is reasonable to arrange the
sensor at a position which:
– is easily accessible for operation
– is free from curtains, cupboards, shelves etc.
– enables free air circulation
– is free from direct sun radiation
– is free from draughts (e.g. opening of windows and
doors)
– is not affected directly by the source of heat
– is not located on an external wall
– is located approx. 1.5 m above floor level
– permits safe radio transmission
– is not in the vicinity of e.g. a radio receiver, a television
set or a radio transmitter
– is not in the vicinity of metal parts e. g. metal doors,
metal cupboards, mirrors or steel reinforced concrete
– if unsure, check radio transmission before installation
(see receiver instructions, section "Radio range test"),
look for suitable position if necessary.
