5.4.6 Pump protection
Pump protection is not activated in the factory. It can, however, be switched on in
the “Service” pump protect menu and then becomes active from 12.00 to 12.01
hrs.
5.4.7 Optimisation
If the optimisation function (1-60 min.) is switched on, the thermostat calculates
the ideal switching time for toggling between lower and comfort mode.
5.4.8 Shock delay
To save energy the thermostat switches off the heating for 4-15 min. by a shock
delay (in the event of a sudden drop in temperature) depending on the height of
the drop in temperature (ventilation etc.). You can switch off shock delay by pres-
sing any key (excluding the Info key) or switching the rotary knob.You can
activate or deactivate the shock delay in the “Service” menu.
The heating error message, for example, will appear if the actual temperature
does not increase after 1 hour.
5.4.9 Reset operating hours
The op hour reset function in the "Service” menu indicates the number of hours
during which the device has been switched on.
The operating hours are requested using the Info key and reset in the "Service”
menu.
5.4.10 Enter password
password appears in the "Service” menu.After confirming with OK, you can
enter the 4-digit code. Confirm each figure with OK.
The password can also be changed or cleared.
Set the rotary switch to Frost and hold down for 5 sec. pressing the OK
and ESC keys at the same time. The password has been cleared.
Once you have entered the password in the "Service” menu, you can select only
the "Display” and "Language” submenus; the entered code is required to access
all other items.
Example 1 (Comfort mode):
The setting is 10 minutes per °C at a room temperature of 17 °C.
However, room temperature should reach 20 °C by 7.00 hrs. The 7.00 hrs switchover
to comfort mode will occur at 6.30 hrs.
➡ 7.00 - 3 x 10 min. = 6.30 hrs.
Example 2 (Lower mode):
The system should be regulated to target temperature (–1 °C) ) during optimisati-
on time and before lower mode.
At 6.00 hrs, we have a room temperature of 15 °C (24 °C). ). At 22.00 hrs, the tem-
perature should be 17 °C.
➡ 24 °C - 17 °C = 7 °C x 10 = 70 minutes
➡ 22 hrs - 70 hrs = 20.50 hrs
From 20.50 hrs onwards, the system is regulated to 23 °C.
