Service Menu
In the service menu, you can manually control the relay outputs R1 – R5.
In the state, the output will remain continuously on; in the state, it will remain continuously off. In the state, the output is controlled by the regulator according to current requirements.
After turning any of the outputs on or off in the service menu, the output status on the main menu page will change to red (off) or green (on). In the Auto mode, the relay status appears white when the output is activated by the regulator, or gray when it is off.
Changing the state of an output in the service menu has the highest priority. Therefore, care must be taken, for example, not to leave output R2 (the electric heating spiral for space heating) on without the circulation pump being activated. This could lead to overheating of the heating element and damage to the heating system.
