When the average of the outdoor temperatures over the past 24 hours reaches 18°C, the regulator switches off the
heating (as an economy measure).

If the installation is tted with an room sensor:
This function enables you to choose the ambient temperature's inuence on the setting.
If no value is entered, the setting is made based on the outdoor temperature.
If the parameter is set at 100%, the setting is only based on the ambient temperature.
74 I Mean outside temperature -50... 50 °C -
Reset : Press the button (+/OK) 2 times.
This is the average of the outdoor temperature over a 24-hour period. This value is used for automatic Summer / Winter
switchover (line 69).

(0) 24h/day : The temperature of the DHW is constantly maintained at the DHW nominal setting.
(1) Time programs HCs : The DHW is produced according to the programming for the ambient temperature
(with 1 hour in advance when switched on).
(2) Time program /DHW : The DHW programme is separate form the heating circuit programme.
(3) Low-tariff * : The electrical backup heating is only authorised to operate during the off-peak period.
(4) T'prog /DHW or low-tariff * : The electrical backup heating is authorised to operate during the nominal period or off-peak.
* - Connect the "Power Provider" contact to input EX2 (E5). (see gure 33, page 28). In the case of a day /night contract,
the electric back-ups for the DHW tank are subject to the power supplier's tariffs. Switching on the electric back-up for
the DHW tank is only authorised during off-peak hours.
