  • Page 8 Modulating central heating control The WiZe clock thermostat measures the room temperature and uses it to determine the area’s heat demand. Depending on room temperature the thermostat determines the water temperature required by the boiler. As a result the boiler also determines the capacity required resulting in optimum heat input to the house combined with the lowest energy consump- tion possible.

  • Page 36: User Recommendations / Holidays

    5.8 User recommendations / holidays Keep radiators placed in the area with the room thermostat always open. The actual temperature and room temperature measured by the thermostat may differ slightly depending on the installation and position of the room thermostat . This may be the case, for instance, when the thermostat is mounted on an outside wall.
  • Page 37 Prevent freezing of your central heating installation When the thermostat has been switched off for both the Com- fort setting and the central heating (the (!) symbol is visible), the thermostat will keep room temperature at a minimum of 5°C (Frost prevention). This is the case when ‘UIT’ (OFF) has been selected in the central heating menu and the tapwater menu.
  • Page 38 The boiler comes on earlier than the time set on the cen- tral heating’s clock program. • The thermostat will want to reach the required temperature at the time set. As a result the boiler will start heating up ear- lier, this is the so-called self-learning switch-on optimization (chapter 1 refers).
  • Page 39 Display faults on the thermostat’s screen The thermostat can also relay boiler faults. Therefore, first check whether the fault is not caused by the connected boiler. Refer to the boiler’s manual for additional explanation regar- ding the boiler fault. If it reads “Err” instead of the temperature then there is so- mething wrong with the boiler’s thermostat.
  • Page 40 Press (»); You can see the boiler’s error-history. When you press (») you will see a list of errors that occurred in the past. Press the menu key ( ) and you will return to the standard screen. Refer to the boiler’s manual to see a description of the codes.

  • Page 41: Dismantling And Loss Of Voltage

    Dismantling and loss of voltage Loss of voltage The thermostat works without batteries and obtains its required energy via the boiler. When the thermostat is removed from its mounting plate, all settings are stored in the memory. Only after an interruption of approximately 4 hours do you have to reset the day and time. Dismantling Disconnect the boiler from the mains (pull the plug from its socket or use the on/off button).
