1. Operating instructions for the user and the qualified installer
The installation and use of electrical appliances
must be carried out with due caution in
order to avoid the risk of fire, electric shock
or injury. The equipment must only be used as
described in these instructions. Any use out-
side of the manufacturer recommendations
could lead to damage, fire, shock or injury.
Before using the appliance the instructions
should be read in their entirety and all
appropriate handling of the equipment must
be observed.
These instructions should be kept
safely and passed on to any future
owner.
In the event of any repair work, hand them
to the qualified installer for his attention.
Unit description
The RTF-Z digital controller enables individu-
al control of the heating mats. There are four
operating programmes.
When connected to the mains electrical supply
the controller switches on and regulates the
floor heating to a preset temperature. The
„heating operating symbol “ is displayed.
After setting the time the controller auto-
matically switches to the timer programme.
By means of the self learning function of the
RTF Z, the start-time will be set directly into
the timer-program, from which the comfort
temperature will be achieved. Due to this, the
start of the heating-time will be before the
adjusted starting time.
The self-learning-function is activated by the
factory, if wished it can be deactivated within
the adjustment mode.
Switching ON & OFF
To switch off, press the
M button and hold
for 3 seconds, the display will then show OFF.
1 Mode - select an operating mode or
function by repeated pressing
2 Reset - restore the factory setting.
Briefly depress the flush-fitting push-
button with a non-conductive blunt object.

Prior to fitting the top covering of the floor, the
temperature probe is to be let into an empty
tube flush with the surface in the foundation
flooring (for example the screed flooring);
see operating and installation instructions for
temperature controlled floor mat.
In the case of a fault live electricity
can be present in the controller or
sensor lead.
2.2 Installing the thermostat
The thermostat is to be inserted into a
standard commercial UP switch box for unit
diameters of 55 mm.
The thermostat is to be inserted as follows:
– Pull off the complete changeable frame (7,
8), to do this grasp the switch frame at the
top and bottom;
– Carry out the electrical connection in
accordance with the connection diagram
and as follows:
t The sensor probes are connected to
the 2 terminals marked „F“.
t The incoming mains electricity should
be connected as follows:
• Live to „L“
• Neutral to „N“
• Earth to Earth terminal on backbox
t The heating mat/s connections should
be as follows:
• Live to „L“
• Neutral to „N“
