AC•THOR: Hot water with a single-phase immersion heater
AC•THOR 9s: Hot water with a three-phase immersion heater
When controlling via Modbus RTU, the operating mode M7 cannot be used!
In this operating mode, an electric heating element is supplied linearly with excess PV energy. In
addition, the AC•THOR can send out a temperature-dependent PWM signal. This can control the
speed of a pump.
This function was tested by my-PV with the pump types Wilo Para PWM1 and PWM2 and Wilo
Varios PICO-STG. For PWM2, the setting command xxx.xxx.xxx.xxx.xxx/setup.jsn?pwmt=2 must
be entered in the URL of the webinterface. For other pumps, the function cannot be certified.
In this operating mode, two my-PV temperature sensors are required!
The output of the PWM signal starts when the target temperature + hysteresis is reached at sensor
2. The signal becomes stronger the further the target temperature + hysteresis is exceeded.
Optionally, the AC•THOR can also take over guaranteeing the hot water temperature. For this, a
third my-PV temperature sensor is to be used.
Note: A temperature sensor is always included with the AC•THOR, other sensors must be purchased
separately.
