AC•THOR 9s – Operation with 3 single-phase heating elements
Our "Support" section offers many practical tips that will help you with the installation and commissioning of our devices.
The load control of 3 single-phase heating elements is a special form of operating mode M1 for hot water.
CAUTION:
This is to be clearly distinguished from operating mode M2 "Layer Charging," where load control is switched to another 3-phase consumer using an external opener and a closer!

Solution
The regular operation for 3 single-phase heating elements can be set with a single adjustment. Simply switch the "Load Priority" accordingly under "Settings" (gear symbol).
Good to know
Tip: Connect the topmost heating element to the control output OUT-3 of the AC•THOR 9s. If you accidentally did not follow the order, simply switch the consumption plugs. This saves rewiring!
