How to fit and setup the device

EXAMPLE NO. 3 – ALL 6 LOADS, CONTROL MODE = EACH PHASE INDEPENDENTLY
Loads specified in example No. 2 but more complex connection. Control mode is set for each phase
independently.
Connect the following to L1 phase:
- boiler has 1st priority (triac No. 1).Requirements are the same as in example No. 1.
- pool filtering pump has 2nd priority (relay No. 1).Requirements are the same as in example No. 2.
Connect the following to L2 phase:
- heating pump has 1st priority (relay No. 2).Requirements are the same as in example No. 2.
- 1st heating coil with 2nd priority (SSR 1).
Connect the following to L3 phase:
- auxiliary contact with 1st priority (triac No. 2 operating as a relay), will also turn on the heating pump
connected actually to phase L2 (here, a small amount of power may be drawn from the public grid at phase L2,
but in order to prevent it we would have to use two circulation pumps).
- 2nd heating coil with 2nd priority (SSR 2).
Unfortunately, in this "one-regulator" configuration setup, the 3rd heating coil cannot be connected. We would
have to make sure that the circulation heating pump will be turned on by one output only - using a time
schedule, or completely separately - outside of WATTrouter.
