E18: Number of hours
Setting of number of hours for continuous run at fan speed mode 3 before automatically switching
back to mode 2.
This option is used by the menu item
E17=1 .
Options: 1-10 hours
Factory setting: 3 hours
E19: Extra function
This function controls relay R9: Solar collector, additional heat sources, heat sink, or damper
control.
Value of 0: This feature is disabled, and the relay is switched off.
Value of 1 (requires a tank with heating coil): The solar collector function which activates an
external solar pump (relay R9). If the T8 temperature (water tank) is lower than the set point in
menu point
E46 (max. water tank temperature), the solar pump function is activated.
The pump will run if the T9 temperature (solar collector) is higher than the T8 temperature (wa-
ter tank) + menu item
E20 (solar collector hysteresis).
The pump stops again when the T9 temperature (solar collector) becomes lower than the T8
temperature (water tank).
This feature is independent of the heat pump running status.
Value of 2 (
requires a tank with heating coil): The floor heating function which activates an
external circulation pump (relay R9). If the T8 temperature (water tank) is higher than the setting
at menu point E13 (floor heating temperature), the floor heating function is activated. The pump
will run, if the T9 temperature (external sensor) is lower than the set point in menu point E2. The
pump (relay R9) stops again when the T9 temperature (external sensor) is higher than the set-
ting at menu point
E2 .
This feature is independent of the heat pump running status.
Value of 3 (requires a tank with heating coil): The solar collector function which activates the
solar pump (relay R9). The solar collector function has an overall safety feature that can turn off
the solar pump.
If the T9 temperature (solar collector) is higher than 89 °C, the pump is turned off. The pump
starts again if the T9 temperature (solar collector) is less than 87 °C.
If the T8 temperature (water tank) is less than the set point in menu point
E46
(max. water tank
temperature), the solar pump function is activated.
The pump (relay R9) stops again when the T9 temperature (solar collector) becomes lower than
the T8 temperature (water tank).
The pump will run if the T9 temperature (solar collector) is higher than the T8 temperature
