Further date and time settings can be made as described in section 5. a) under item 2.
d) Setting the security code, ‘CODE’
As already described, the radio-controlled radiator thermostat system has a two part security code to protect it from
interference from other wireless systems.
Each part has over 100 different possible settings, which means that 10,000 different security codes are available.
To ensure communication between the control centre and the FHT 8V valve operating mechanism/s, the same security code
has to be set for all the devices in a room.
Ö
This is particularly important, if more than one valve operating mechanism is used or no set (control centre
and valve operating mechanism) was purchased.
When you purchase a set, the control centre and the valve operating mechanism have already been assigned
a (random) security code, which means that you do not normally have to carry out any additional settings.
If the code needs to be changed or transmitted again, proceed as follows:
• Keep the ‘PROG’ button pressed until ‘Sond’ (special) appears on the display. Then release the ‘PROG’ button again.
• Use the scroller to select the special ‘CODE’ function.
• Confirm this by briefly pressing the ‘PROG’ button.
• ‘CODE 1’ and a 2-digit number appear on the display.
Ö
This number is the first part of the currently active security code (for instance, ‘12’).
• Set the first part of the code (00 to 99) using the scroller.
• Confirm the code by briefly pressing the ‘PROG’ button.
• ‘CODE 2’ and a 2-digit number appear on the display.
Ö
This number is the second part of the currently active security code (for instance, ‘34’).
