1. Specifications This chapter explains how the clock thermostat and some of its functions work. • • • • • • • • • • No batteries. Loss of voltage Manual mode Central heating’s clock program. Self-learning switch-on optimization: Comfortably warm on time. Additional savings in Economy setting. On-screen device information. Modulating central heating control. Weather dependent control. Timer function. No batteries For its functioning the clock thermostat receives its energy from the connected boiler.
Self-learning: Comfortably warm on time (only in automatic mode) The self-learning switch-on optimization ensures that the required temperature is reached at the time programmed. Since outside temperatures vary daily, the thermostat re-determines every day at what time the boiler has to start up in the morning to ensure it being warm on time. If that temperature has not been reached at the time set, it will start heating up earlier the next morning. The same applies the other way round.
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 consumption possible. Weather dependent control The WiZe clock thermostat can also be used as a weather dependent control.
2. Mounting and initial operation 2.1 Mounting 2.2 Initial operation 9 11 2.1 Mounting A .Choose a suitable location for mounting the thermostat. Suitable mounting location: At a height of approx. 1.5 m, away from windows and doors; on an internal wall without obstacles around the room thermostat. Wrong mounting places: • In a place where the sun can shine directly on the thermostat. • On a cold outside wall (maybe fitting insulation material behind the thermostat).
B. Remove the rear panel C. Mount the rear panel on the wall (A refers) Use the rear panel as a template to mark the holes! Seal the hole where the wiring originates to prevent likely draught. Use the screws and plugs supplied. D. Fit wiring to rear panel Make sure that the boiler plug has been removed from its socket! Only connect the wiring to the Z-ready/bus thermostat connection of the boiler.

The correct pressure has to be between 1.4 and 1.7 bar. Also have a look at the boiler to read the water pressure allowing you a proper check and top up if required. You may also refer to the boiler’s manual. 3. Central heating’s input temperature inside the boiler 4.
5.5 Adjusting DHW and CH set point All ATAG boilers allow for adjustment of the hot water temperature setting (= tapwater setpoint) and maximum central heating temperature (= central heating setpoint). When the WiZe thermostat is connected to the boiler, these adjustments may be set on both the boiler and thermostat. The last setting is always the current setting, regardless of where (boiler or thermostat) the setting has been activated. Please refer also to the boiler’s manual.
You can adjust the tapwater setpoint as follows: Press ; Press (»); Press (SET); Press a number of times on (») until you see DHW SETP. DHW SETP = DHW-setpoint (= control value for hot water temperature). Recommendation: Do not change the setpoint if it is not urgently required. ATTENTION!

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. Consult your installer for further information.
Prevent freezing of your central heating installation When the thermostat has been switched off for both the Comfort 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. However, it is advisable not to set the thermostat lower than approx. 12°C.
The boiler comes on earlier than the time set on the central 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 earlier, this is the so-called self-learning switch-on optimization (chapter 1 refers). The boiler’s starting time may be different every day, because the moment the thermostat has to come on to reach the required temperature on time is being recalculated every day. This is a normal situation.
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 regarding the boiler fault. If it reads “Err” instead of the temperature then there is something wrong with the boiler’s thermostat.
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. The central heating’s pressure is too low. Top up the central heating system. Refer to the boiler’s manual for additional explanations in this respect. This fault implies that the thermostat is not working. Consult your installer.
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). • The thermostat hinges at the top and is clamped at the bottom (in the middle).
