9s Operating instructions, version a0020806 21
specified. Factory settings are number of days 7, starting time 8 pm, temperature is 60 °C, the
legionella program is "Off".
This enables the heat-pump and the immersion heating element remains in "excess" operation.
Relay thresholds
As switching threshold for a heat-pump, any output between 0 and 9,999 W can be set. Factory
setting is 500 W. An alteration to this output threshold only becomes effective after the end of the
current control cycle or after the AC•THOR is restarted.
Optionally, simultaneous control of the AC•THOR load output can be deactivated on the right of the
screen.
Relay delay
A period in minutes is laid down (t P>), during which the switching threshold above must at least be
exceeded before the heat-pump is enabled. The factory setting suggests 15 minutes. After this, a
minimum operating period (t run) and a minimum pause duration (t wait) can be set for the heat-
pump. Factory settings suggest 30 minutes for both these values
AC•THOR: Hot water + one heating zone
AC•THOR 9s: Hot water + two heating zones
This operating mode is intended for buildings with hot water and space heating by electricity.
Electrical heat sources are supplied with PV surplus one after the other linearly with power. The
immersion heating element for the hot water supply takes priority. As soon as the hot water target
temperature at the respective my-PV temperature sensor is reached, next the electric space heating
is supplied until here too the target value at the my-PV temperature sensor is reached.
Optionally, the AC•THOR can also take over guaranteeing the hot water temperature.
Two my-PV temperature sensors are required for AC•THOR!
Three my-PV temperature sensors are required for AC•THOR 9s!
Note: One temperature sensor is always included with the AC•THOR, other sensors must be
purchased separately.
The first my-PV temperature sensor is in any case to be sited over the heater in the hot water
tank to provide a reliable reading!
Note for AC•THOR 9s as of Ethernet firmware version a0020806
Compared to previous versions, there is now the following advantage: If a minimum
temperature must be ensured with maximum power at room heating 1 (output Out-1), then the
AC•THOR 9s can still control power at outputs Out-2 (room heating 2) or Out-3 (hot water)
during this time, provided the target temperature has not yet been reached at these and there
is still surplus.
From version a0020806 onwards, a 2-pole changeover contact must be provided in the
installation for this purpose, which is actuated by the potential-free contact of the AC•THOR 9s.
For wiring details, please refer to the installation instructions enclosed with the unit. You can
also find the latest information at any time at www.my-pv.com.
Note: A firmware update does not change the previous operating mode of already installed
units that are used in the M5 operating mode.
