9s Operating instructions, version a0020000 17
M5: Hot water + Space heating
AC•THOR: Hot water + one heating zone
AC•THOR 9s: Hot water + two heating zones
Explanation
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!
For controlling the space heating, the respective my-PV temperature sensor is to be installed
in a suitable place to provide a reliable reading!
With electric underfloor heating for instance in a probe-tube in the floor.
If measuring the air in the room, avoid direct sunlight.
TIP: When specifying room temperatures, to avoid using power from the public grid
the minimum values for day and night should be set correspondingly low. See
explanation "SH 1 temperatures".
