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.
